Direct Answer

> TL;DR: Aviation MRO sales in 2027 lives or dies on nine numbers: contract win rate (22-30% on engine LTSAs, 35-45% on airframe checks), average contract value ($8M-$45M for engine LTSAs, $180K-$2.4M per airframe check), pipeline coverage (4.5-6x on rolling 18-month book), AOG response time (under 4 hours commitment, 90%+ SLA hit rate), turnaround time variance (-/+ 3 days against contract TAT), parts attach rate (28-42% of labor revenue), contract renewal rate (78-88% on multi-year LTSAs), gross margin by line (engine 18-24%, components 32-40%, line maintenance 12-16%), and customer concentration (top-5 under 55% of book). Quotes take 90-180 days. Buyers are VP Maintenance, Fleet Directors, and Military Program Managers — they care about dispatch reliability, regulatory exposure, and total cost per flight hour.

Why Aviation MRO Sells Differently

Aviation MRO is not a typical industrial services sale. Four mechanics shape every deal.

1. Regulatory gravity controls the buyer. FAA Part 145, EASA Part-145, Transport Canada AMO, and military airworthiness directives sit in every conversation. Your buyer cannot move work to an unapproved station, no matter how good your price is. Capability lists, OEM authorizations (CFM, Pratt, GE, Rolls-Royce, Honeywell), and DER/DOA authority gate the entire pipeline. A 30-minute "are you approved on -7B27A?" call kills more deals than price ever does. Sales reps who cannot answer capability questions in real time lose the slot before the RFP arrives.

2. The asset, not the customer, drives the cycle. Engine shop visits are forecasted by cycles since last shop visit (CSLSV), LLP life remaining, and EGT margin trends. Airframe C-checks and D-checks are scheduled by flight hours and calendar months. This means you are not selling against a buying window the customer invents — you are selling against a tail number's maintenance program. Win or lose, the slot exists. Customer relationship management built around opportunity stages misses this: the better record is tail-number by tail-number, with planned induction date, scope, and competitor incumbent.

3. AOG (Aircraft on Ground) economics warp pricing. A grounded narrowbody costs an airline $10K-$25K per hour in lost revenue. A grounded widebody runs $40K-$90K per hour. When a customer calls with an AOG, price elasticity disappears for 24-72 hours. Sales teams that build dedicated AOG desks, pre-positioned exchange pools, and 2-hour quote SLAs convert AOG events into multi-year contracts. Teams that route AOG through standard quote workflows lose the relationship within two events.

4. Long-Term Service Agreements lock revenue for a decade. Engine LTSAs (Rolls-Royce TotalCare, GE OnPoint, Pratt EngineWise, CFM RPFH) and component pool agreements run 8-15 years. Win one and you have an annuity. Lose one and you wait a decade for re-bid. This makes pipeline coverage on LTSAs the most strategic metric in the entire book — a thin LTSA pipeline three years out predicts a revenue cliff that no transactional work can backfill.

The 9 KPIs, In Depth

1. Contract Win Rate by Product Line. Track separately for engine LTSAs, engine T&M shop visits, airframe heavy checks, line maintenance contracts, component repair, and parts/exchange pools. Benchmark: engine LTSAs 22-30%, engine T&M 38-48%, airframe heavy checks 35-45%, line maintenance 28-36%, components 42-52%. Anything under 20% on LTSAs means you are being used as a stalking horse against the OEM incumbent. Measure by quote count and by ACV-weighted win rate — the gap between the two reveals whether you are winning small and losing big.

2. Average Contract Value (ACV). Engine LTSAs: $8M-$45M per tail over 10-12 years for narrowbody (CFM56, LEAP-1A/B, V2500), $35M-$120M for widebody (GEnx, Trent XWB, GE9X). Airframe heavy checks: $180K-$650K for A-check, $850K-$2.4M for C-check, $3M-$8M for D-check. Line maintenance per-station contracts: $1.2M-$4.5M annually. Components: $40K-$280K per shop visit. Track ACV trajectory by year — flat ACV in a market where labor rates rose 6-9% annually means you are losing scope, not holding pricing.

3. Pipeline Coverage on Rolling 18-Month Forecast. Target 4.5-6x of period quota. MRO sales cycles run 90-180 days for shop visits and 12-36 months for LTSAs, so a thin pipeline today is a revenue gap that cannot be closed with hustle. Segment coverage by induction quarter and by aircraft type. If your A320 family coverage is 7x but your 787 coverage is 1.8x, you have a widebody capability problem that no amount of pipeline review will fix.

4. AOG Response Time and SLA Hit Rate. Industry standard for premium contracts: under 4 hours from customer call to dispatched team or parts shipment. Track quote-to-AOG-customer median (target under 90 minutes), parts pick-and-ship (under 2 hours for pool members), and on-site team arrival (under 12 hours domestic, under 24 hours international). SLA hit rate above 92% protects renewals; under 85% triggers contract penalties of 8-15% of annual contract value and almost always loses the next bid.

5. Turnaround Time (TAT) Variance. Contract TAT for a narrowbody C-check sits at 18-28 days; engine shop visit TAT runs 65-95 days depending on scope (performance restoration vs. full overhaul). Variance against contract TAT is the single number airline VPs watch. Hitting TAT -/+ 3 days at 90%+ frequency commands a 7-12% pricing premium. Slipping TAT by more than 5 days on more than 15% of inductions triggers a re-bid within 18 months.

6. Parts Attach Rate. Parts, exchange, and rotables revenue as a percentage of labor revenue per shop visit. Benchmark: 28-42% on engine shop visits, 18-26% on airframe heavy checks, 35-48% on component repairs. Higher attach correlates with engineering quality (catching latent defects), parts inventory positioning, and customer trust to accept your findings. Attach below 22% on engines usually means the customer is splitting work to their own parts pool — a renewal risk signal.

7. Contract Renewal Rate. LTSAs: 78-88%; airframe heavy maintenance multi-year deals: 72-82%; line maintenance: 68-78%. Track 36 months before contract expiry — renewal motions started inside 18 months lose to incumbent OEMs and to lower-cost MROs in Asia. Renewal rate under 70% means you are winning new logos to replace churn, which is 3-4x more expensive than retention and rarely scales.

8. Gross Margin by Line of Business. Engine MRO: 18-24% gross margin (lower on LTSA early years, higher mid-contract). Airframe heavy: 12-18%. Line maintenance: 12-16%. Components and accessories: 32-40%. Parts trading and pool revenue: 22-30%. Margin compression of more than 200 basis points year-over-year usually signals either scope creep accepted without re-quote or labor productivity slippage — both fixable with disciplined ops review.

9. Customer Concentration. Top-5 customers under 55% of total book; top-10 under 75%. Above these thresholds, a single airline fleet decision (retirement, sale-leaseback, MRO consolidation) can wipe 15-25% of revenue in one announcement. Track concentration by airline parent, by aircraft platform, and by engine type — a book that looks diversified by customer name can still be 80% concentrated on a single engine variant.

Real Operators

GE Aerospace Services runs OnPoint LTSAs on GE90, GEnx, GE9X, CF6, and CFM (joint venture with Safran) engine families. Their TrueChoice portfolio offers transactional, material-only, and full LTSA pricing — sales teams quote off configurator tools tied directly to engine fleet data they pull from customer dispatch systems. Renewal rates on widebody LTSAs sit in the high 80s.

Pratt & Whitney EngineWise services PW1000G geared turbofan, PW4000, V2500 (with IAE partners), and PW800 business aviation engines. EngineWise contracts bundle health monitoring (EHM data feeds), shop visit management, and LLP planning. Their global network of 30+ MRO facilities (including JV partners) lets them commit to AOG response under 6 hours in major regions.

Rolls-Royce TotalCare is the original LTSA model — power-by-the-hour on Trent 700, Trent 800, Trent 900, Trent 1000, Trent XWB, and Trent 7000. TotalCare covers over 95% of widebody Trent fleet hours. Sales motion is fleet-level with airline CFOs and treasury teams, not just maintenance directors, because TotalCare converts CapEx volatility into predictable cost-per-flight-hour.

Lufthansa Technik is the largest independent MRO, covering airframe, engine (CFM56, V2500, GE90, Trent, PW1000G), components, and VIP completions. Their Total Component Support (TCS) and Total Engine Support (TES) bundle reliability guarantees with pool access. AMOS, the MRO software platform owned by Lufthansa subsidiary Swiss-AS, runs at more than 220 airlines and MROs — Lufthansa Technik's data position is a structural sales advantage.

AAR Corp runs airframe heavy maintenance at Indianapolis, Miami, Oklahoma City, Rockford, and Trois-Rivieres, plus government services and parts distribution. AAR's parts trading and supply chain business pulls airframe customers into multi-line contracts. They publicly report quarterly MRO revenue, segment margins, and book-to-bill — useful comp data for any operator setting their own pricing.

StandardAero services regional, business aviation, military, and energy turbines (CFE738, PT6, PW100, AE3007, T56, RB211 industrial). Their position in business aviation engines (Honeywell HTF7000, Rolls-Royce AE3007, BR710) makes them dominant in that segment with manufacturer authorizations. Acquired by Carlyle and now publicly traded, they disclose detailed MRO segment economics.

ST Engineering Aerospace runs airframe heavy maintenance across Singapore, China, US (Mobile, San Antonio, Pensacola), and Europe. Strong on narrowbody (A320, 737) and growing on widebody. Their nacelles, components, and engine MRO segments diversify the book away from pure airframe cyclicality.

MTU Maintenance is the largest independent engine MRO, with shops in Germany, Canada, China, Poland, Malaysia, and the US (Dallas via JV with Pratt). MTU covers V2500, CF6, CF34, CFM56, GEnx, GP7000, PW1000G, and PW2000. Their MTUPlus engine leasing pool gives airlines green-time engine access during shop visits — a structural pricing lever.

HAECO Group runs airframe (Hong Kong, Xiamen, USA via HAECO Americas), engine (Singapore via SAESL JV with Rolls-Royce on Trent 700/800/900), and components. HAECO's regional position in Asia-Pacific narrowbody is dominant; their cabin solutions and inflight services pull adjacent revenue.

Delta TechOps is the largest airline-affiliated MRO, servicing third parties as well as Delta's own fleet. They cover CFM56, CF6, PW2000, PW4000, V2500, GEnx, Trent XWB engines, plus airframe and components. Their internal Delta dispatch reliability data is a powerful sales asset when pitching other carriers.

Failure Modes

1. Quoting by Catalog Instead of by Tail. Teams that quote off engine model and generic workscope without pulling actual ECM trend data, LLP status, and operator dispatch history lose to MROs who walk in with tail-specific findings. The fix is tying CRM opportunity records to tail number, last shop visit summary, current EGT margin, and LLP cycles remaining — then quoting against actual asset condition, not catalog.

2. AOG Routed Through Standard Quote Workflow. When an AOG call hits a sales rep who has to "circle back tomorrow with pricing," the customer is gone. AOG events demand a dedicated desk staffed 24/7, pre-approved pricing matrices for parts exchanges, and authority for the on-call rep to commit to dispatch without escalation. Operators without this lose 60-70% of AOG opportunities and the multi-year contracts that follow them.

3. Treating Heavy Maintenance Like Hangar Bookings. Heavy maintenance is not "fill the dock" — it is multi-year capacity planning against airline maintenance program forecasts. Sales teams that chase quarterly bookings miss the 24-36 month strategic conversation with airline VP Tech Ops. The result is a hangar full of one-off C-checks at spot pricing, no LTSAs, and margins compressing every renewal cycle.

4. Ignoring the Parts and Pool Adjacency. Customers who buy parts from your distribution business renew shop visits at 12-18 percentage points higher than parts-only customers. Sales teams structured in silos (engine sales, parts sales, component pool sales reporting to different VPs) miss the cross-sell motion entirely. The operators with the strongest renewal rates run integrated account teams that quote labor, parts, exchange, and pool access as a single offer.

Reporting Cadence

Daily. AOG board: open events, response time clock, parts pick status. Quote backlog: count by line of business, aged over 48 hours flagged. Hangar slot utilization vs. plan — every empty slot inside 30 days is a margin event.

Weekly. Win/loss by line of business with reason coded (capability, price, TAT, relationship, OEM exclusive). Pipeline movement: dollars added, dollars closed, dollars slipped, by induction quarter. TAT variance against contract for inductions completed in the prior week, segmented by aircraft type.

Monthly. Bookings vs. quota by region and product line. Gross margin by program (every LTSA reviewed against year-of-contract margin curve — early years should run leaner; flat margin year five means scope drift). Renewal pipeline 36 months out, with motion status on every contract over $5M ACV.

Quarterly. Customer concentration by parent airline, by aircraft platform, by engine type. Capability gap analysis: aircraft types entering service in your customer base where you do not yet hold approvals (787-10, A321XLR, A350F, COMAC C919 in selected geographies). LTSA re-bid forecast — every LTSA expiring in the next 60 months mapped against incumbent strength and your competitive position.

30/60/90 Day Plan

Days 1-30: Foundation and Truth. Pull every active contract into one register: tail number list, contract type, ACV, TAT commitment, renewal date, account owner. Audit CRM data integrity — most MRO sales orgs have opportunity records that do not tie to actual tail numbers. Fix that first. Sit through three AOG events end-to-end (from customer call to redelivery) to understand handoff failures. Read the last six months of post-shop-visit reports for the top-10 accounts; find the latent defect callouts that did not turn into follow-up opportunities. Set up the nine KPI dashboards inside Salesforce, AMOS, Trax, or Ramco — pick one source of truth per metric and freeze the definitions.

Days 31-60: Tighten the Quote and AOG Engines. Build a tail-specific quote template that pulls ECM trend, LLP status, and last-visit findings before pricing. Stand up (or refine) a dedicated AOG desk with pricing authority — including pre-approved exchange unit pricing for the top 30 part numbers driving your AOG volume. Run a win-loss review on every quote lost in the prior 12 months over $250K; categorize by capability, price, TAT, relationship, or OEM exclusivity. Start the LTSA renewal motion on every contract expiring inside 36 months — incumbent loses the deal more often when the conversation starts inside 18 months. Set up a weekly capability gap review tied to your customer fleet roadmap (every 787-10 induction in your customer base where you lack approval is a forecasted loss).

Days 61-90: Renewal, Cross-Sell, and Forward Coverage. Push parts and pool cross-sell into every airframe and engine account team — integrated account plans, not siloed quotas. Build the 36-month LTSA renewal forecast with motion status and competitive read on each deal. Re-cut customer concentration with the new clean data and decide which segments need a deliberate diversification push (regional carriers, cargo, business aviation, military) versus which are healthy. Lock in quarterly business reviews with the top-10 customers — formal QBRs with operations data, not just relationship lunches. Confirm the next 18 months of induction slot coverage is at 4.5x or better; if not, you have a pipeline emergency that no late-quarter discounting will fix.

FAQ

Q1: Should we sell engine MRO as power-by-the-hour or transactional? A: Both — but the mix decides your margin profile and your sales motion. Power-by-the-hour (LTSA, TotalCare, OnPoint, EngineWise) gives you 10-15 year revenue visibility and 78-88% renewal rates, but margins are thin in early contract years and you absorb shop-visit variance risk. Transactional T&M shop visits give you 38-48% win rates and higher per-event margins, but no revenue annuity. Most strong MRO operators target 55-70% of engine revenue under LTSA-style contracts, with the balance T&M to keep pricing discipline and capacity flex.

Q2: How do we sell against the OEM on engine LTSAs? A: You will not win on the engine OEM's own approved data — they have it first and they price it tighter. You win on response time (independent MROs commit faster AOG support in regions where the OEM is thin), workscope flexibility (OEM LTSAs often mandate full performance restoration when the customer would accept a lighter scope), parts strategy (independents accept used serviceable material and PMA parts where OEMs do not), and customer service (dedicated account team vs. OEM call center). Quantify the cost-per-flight-hour delta in writing — typically 8-14% lower than OEM equivalent — and back it with mean-time-between-removal data from comparable fleets.

Q3: What MRO software do customers expect us to integrate with? A: AMOS (Swiss-AS, owned by Lufthansa Systems group), Trax, and Ramco Aviation cover the bulk of airline maintenance systems. CAMP and Aerotrac handle business aviation. Military programs run on GOLDesp, NTCSS, or program-specific maintenance management systems. Your CRM (typically Salesforce in MRO sales) needs API connections into the customer's system of record to pull tail number, flight hours, cycle counts, and induction forecasts. Operators without these integrations quote slower and lose to MROs who walk in with current asset data.

Q4: How do we handle pricing escalation in multi-year contracts? A: Tie escalation to a published index, not internal cost. Common formulas: 40-50% labor (BLS aerospace labor index or local equivalent), 30-40% materials (CPI aerospace materials or PPI), 10-20% fixed. Cap annual escalation at 4-6% to keep customer comfort, and include a re-opener clause if the index moves more than 8% in any 24-month window. Avoid "cost-plus" language — airline procurement teams reject it on sight. The strongest contracts have transparent escalation that the customer's procurement can model independently.

Q5: What does dispatch reliability have to do with sales? A: Everything. Airlines tie maintenance vendor performance to fleet dispatch reliability targets (typically 99.0-99.5% schedule completion). If your shop visits, line maintenance, or component repairs correlate with delays or cancellations, you become a quantified problem in the next QBR. The best sales teams pull dispatch reliability data from customers monthly, segment it by aircraft type and by MRO vendor, and walk into renewal meetings with proof of dispatch contribution. Vendors who cannot speak the dispatch reliability language are speaking a different language than the customer.

Q6: How early do LTSA renewals need to start? A: 36 months minimum, 48 months ideal. LTSA decisions go through airline tech ops, finance, treasury, and often board approval. Incumbent advantage compresses inside 24 months because the customer's switching cost (data migration, parts pool transfer, approval re-validation) becomes a deterrent. If you are the incumbent, start renewal conversations 48 months out with fleet evolution discussions. If you are the challenger, start at 36 months with a benchmark study quantifying current contract performance against your offer.

**1. Contract Win Rate by Product Line.** Track separately for engine LTSAs, engine T&M shop visits, airframe heavy checks, line maintenance contracts, component repair, and parts/exchange pools. Benchmark: engine LTSAs 22-30%, engine T&M 38-48%, airframe heavy checks 35-45%, line maintenance 28-36%, components 42-52%. Anything under 20% on LTSAs means you are being used as a stalking horse against the OEM incumbent. Measure by quote count and by ACV-weighted win rate — the gap between the two reveals whether you are winning small and losing big.

**2. Average Contract Value (ACV).** Engine LTSAs: $8M-$45M per tail over 10-12 years for narrowbody (CFM56, LEAP-1A/B, V2500), $35M-$120M for widebody (GEnx, Trent XWB, GE9X). Airframe heavy checks: $180K-$650K for A-check, $850K-$2.4M for C-check, $3M-$8M for D-check. Line maintenance per-station contracts: $1.2M-$4.5M annually. Components: $40K-$280K per shop visit. Track ACV trajectory by year — flat ACV in a market where labor rates rose 6-9% annually means you are losing scope, not holding pricing.

Track quote-to-AOG-customer median (target under 90 minutes), parts pick-and-ship (under 2 hours for pool members), and on-site team arrival (under 12 hours domestic, under 24 hours international). SLA hit rate above 92% protects renewals; under 85% triggers contract penalties of 8-15% of annual contract value and almost always loses the next bid.

**5. Turnaround Time (TAT) Variance.** Contract TAT for a narrowbody C-check sits at 18-28 days; engine shop visit TAT runs 65-95 days depending on scope (performance restoration vs. full overhaul). Variance against contract TAT is the single number airline VPs watch. Hitting TAT -/+ 3 days at 90%+ frequency commands a 7-12% pricing premium. Slipping TAT by more than 5 days on more than 15% of inductions triggers a re-bid within 18 months.

**6. Parts Attach Rate.** Parts, exchange, and rotables revenue as a percentage of labor revenue per shop visit. Benchmark: 28-42% on engine shop visits, 18-26% on airframe heavy checks, 35-48% on component repairs. Higher attach correlates with engineering quality (catching latent defects), parts inventory positioning, and customer trust to accept your findings. Attach below 22% on engines usually means the customer is splitting work to their own parts pool — a renewal risk signal.

**7. Contract Renewal Rate.** LTSAs: 78-88%; airframe heavy maintenance multi-year deals: 72-82%; line maintenance: 68-78%. Track 36 months before contract expiry — renewal motions started inside 18 months lose to incumbent OEMs and to lower-cost MROs in Asia. Renewal rate under 70% means you are winning new logos to replace churn, which is 3-4x more expensive than retention and rarely scales.

**8. Gross Margin by Line of Business.** Engine MRO: 18-24% gross margin (lower on LTSA early years, higher mid-contract). Airframe heavy: 12-18%. Line maintenance: 12-16%. Components and accessories: 32-40%. Parts trading and pool revenue: 22-30%. Margin compression of more than 200 basis points year-over-year usually signals either scope creep accepted without re-quote or labor productivity slippage — both fixable with disciplined ops review.

**9. Customer Concentration.** Top-5 customers under 55% of total book; top-10 under 75%. Above these thresholds, a single airline fleet decision (retirement, sale-leaseback, MRO consolidation) can wipe 15-25% of revenue in one announcement. Track concentration by airline parent, by aircraft platform, and by engine type — a book that looks diversified by customer name can still be 80% concentrated on a single engine variant.

## Real Operators

**GE Aerospace Services** runs OnPoint LTSAs on GE90, GEnx, GE9X, CF6, and CFM (joint venture with Safran) engine families. Their TrueChoice portfolio offers transactional, material-only, and full LTSA pricing — sales teams quote off configurator tools tied directly to engine fleet data they pull from customer dispatch systems. Renewal rates on widebody LTSAs sit in the high 80s.

**Pratt & Whitney EngineWise** services PW1000G geared turbofan, PW4000, V2500 (with IAE partners), and PW800 business aviation engines. EngineWise contracts bundle health monitoring (EHM data feeds), shop visit management, and LLP planning. Their global network of 30+ MRO facilities (including JV partners) lets them commit to AOG response under 6 hours in major regions.

**Rolls-Royce TotalCare** is the original LTSA model — power-by-the-hour on Trent 700, Trent 800, Trent 900, Trent 1000, Trent XWB, and Trent 7000. TotalCare covers over 95% of widebody Trent fleet hours. Sales motion is fleet-level with airline CFOs and treasury teams, not just maintenance directors, because TotalCare converts CapEx volatility into predictable cost-per-flight-hour.

**Lufthansa Technik** is the largest independent MRO, covering airframe, engine (CFM56, V2500, GE90, Trent, PW1000G), components, and VIP completions. Their Total Component Support (TCS) and Total Engine Support (TES) bundle reliability guarantees with pool access. AMOS, the MRO software platform owned by Lufthansa subsidiary Swiss-AS, runs at more than 220 airlines and MROs — Lufthansa Technik's data position is a structural sales advantage.

**AAR Corp** runs airframe heavy maintenance at Indianapolis, Miami, Oklahoma City, Rockford, and Trois-Rivieres, plus government services and parts distribution. AAR's parts trading and supply chain business pulls airframe customers into multi-line contracts. They publicly report quarterly MRO revenue, segment margins, and book-to-bill — useful comp data for any operator setting their own pricing.

**StandardAero** services regional, business aviation, military, and energy turbines (CFE738, PT6, PW100, AE3007, T56, RB211 industrial). Their position in business aviation engines (Honeywell HTF7000, Rolls-Royce AE3007, BR710) makes them dominant in that segment with manufacturer authorizations. Acquired by Carlyle and now publicly traded, they disclose detailed MRO segment economics.

**ST Engineering Aerospace** runs airframe heavy maintenance across Singapore, China, US (Mobile, San Antonio, Pensacola), and Europe. Strong on narrowbody (A320, 737) and growing on widebody. Their nacelles, components, and engine MRO segments diversify the book away from pure airframe cyclicality.

**MTU Maintenance** is the largest independent engine MRO, with shops in Germany, Canada, China, Poland, Malaysia, and the US (Dallas via JV with Pratt). MTU covers V2500, CF6, CF34, CFM56, GEnx, GP7000, PW1000G, and PW2000. Their MTUPlus engine leasing pool gives airlines green-time engine access during shop visits — a structural pricing lever.

**HAECO Group** runs airframe (Hong Kong, Xiamen, USA via HAECO Americas), engine (Singapore via SAESL JV with Rolls-Royce on Trent 700/800/900), and components. HAECO's regional position in Asia-Pacific narrowbody is dominant; their cabin solutions and inflight services pull adjacent revenue.

**Delta TechOps** is the largest airline-affiliated MRO, servicing third parties as well as Delta's own fleet. They cover CFM56, CF6, PW2000, PW4000, V2500, GEnx, Trent XWB engines, plus airframe and components. Their internal Delta dispatch reliability data is a powerful sales asset when pitching other carriers.

## Failure Modes

**1. Quoting by Catalog Instead of by Tail.** Teams that quote off engine model and generic workscope without pulling actual ECM trend data, LLP status, and operator dispatch history lose to MROs who walk in with tail-specific findings. The fix is tying CRM opportunity records to tail number, last shop visit summary, current EGT margin, and LLP cycles remaining — then quoting against actual asset condition, not catalog.

**2. AOG Routed Through Standard Quote Workflow.** When an AOG call hits a sales rep who has to "circle back tomorrow with pricing," the customer is gone. AOG events demand a dedicated desk staffed 24/7, pre-approved pricing matrices for parts exchanges, and authority for the on-call rep to commit to dispatch without escalation. Operators without this lose 60-70% of AOG opportunities and the multi-year contracts that follow them.

**3. Treating Heavy Maintenance Like Hangar Bookings.** Heavy maintenance is not "fill the dock" — it is multi-year capacity planning against airline maintenance program forecasts. Sales teams that chase quarterly bookings miss the 24-36 month strategic conversation with airline VP Tech Ops. The result is a hangar full of one-off C-checks at spot pricing, no LTSAs, and margins compressing every renewal cycle.

**4. Ignoring the Parts and Pool Adjacency.** Customers who buy parts from your distribution business renew shop visits at 12-18 percentage points higher than parts-only customers. Sales teams structured in silos (engine sales, parts sales, component pool sales reporting to different VPs) miss the cross-sell motion entirely. The operators with the strongest renewal rates run integrated account teams that quote labor, parts, exchange, and pool access as a single offer.

```

**Daily.** AOG board: open events, response time clock, parts pick status. Quote backlog: count by line of business, aged over 48 hours flagged. Hangar slot utilization vs. plan — every empty slot inside 30 days is a margin event.

**Weekly.** Win/loss by line of business with reason coded (capability, price, TAT, relationship, OEM exclusive). Pipeline movement: dollars added, dollars closed, dollars slipped, by induction quarter. TAT variance against contract for inductions completed in the prior week, segmented by aircraft type.

**Monthly.** Bookings vs. quota by region and product line. Gross margin by program (every LTSA reviewed against year-of-contract margin curve — early years should run leaner; flat margin year five means scope drift). Renewal pipeline 36 months out, with motion status on every contract over $5M ACV.

**Quarterly.** Customer concentration by parent airline, by aircraft platform, by engine type. Capability gap analysis: aircraft types entering service in your customer base where you do not yet hold approvals (787-10, A321XLR, A350F, COMAC C919 in selected geographies). LTSA re-bid forecast — every LTSA expiring in the next 60 months mapped against incumbent strength and your competitive position.

## 30/60/90 Day Plan

**Days 1-30: Foundation and Truth.** Pull every active contract into one register: tail number list, contract type, ACV, TAT commitment, renewal date, account owner. Audit CRM data integrity — most MRO sales orgs have opportunity records that do not tie to actual tail numbers. Fix that first. Sit through three AOG events end-to-end (from customer call to redelivery) to understand handoff failures. Read the last six months of post-shop-visit reports for the top-10 accounts; find the latent defect callouts that did not turn into follow-up opportunities. Set up the nine KPI dashboards inside Salesforce, AMOS, Trax, or Ramco — pick one source of truth per metric and freeze the definitions.

**Days 31-60: Tighten the Quote and AOG Engines.** Build a tail-specific quote template that pulls ECM trend, LLP status, and last-visit findings before pricing. Stand up (or refine) a dedicated AOG desk with pricing authority — including pre-approved exchange unit pricing for the top 30 part numbers driving your AOG volume. Run a win-loss review on every quote lost in the prior 12 months over $250K; categorize by capability, price, TAT, relationship, or OEM exclusivity. Start the LTSA renewal motion on every contract expiring inside 36 months — incumbent loses the deal more often when the conversation starts inside 18 months. Set up a weekly capability gap review tied to your customer fleet roadmap (every 787-10 induction in your customer base where you lack approval is a forecasted loss).

**Days 61-90: Renewal, Cross-Sell, and Forward Coverage.** Push parts and pool cross-sell into every airframe and engine account team — integrated account plans, not siloed quotas. Build the 36-month LTSA renewal forecast with motion status and competitive read on each deal. Re-cut customer concentration with the new clean data and decide which segments need a deliberate diversification push (regional carriers, cargo, business aviation, military) versus which are healthy. Lock in quarterly business reviews with the top-10 customers — formal QBRs with operations data, not just relationship lunches. Confirm the next 18 months of induction slot coverage is at 4.5x or better; if not, you have a pipeline emergency that no late-quarter discounting will fix.

## FAQ

**Q1: Should we sell engine MRO as power-by-the-hour or transactional?**
A: Both — but the mix decides your margin profile and your sales motion. Power-by-the-hour (LTSA, TotalCare, OnPoint, EngineWise) gives you 10-15 year revenue visibility and 78-88% renewal rates, but margins are thin in early contract years and you absorb shop-visit variance risk. Transactional T&M shop visits give you 38-48% win rates and higher per-event margins, but no revenue annuity. Most strong MRO operators target 55-70% of engine revenue under LTSA-style contracts, with the balance T&M to keep pricing discipline and capacity flex.

**Q2: How do we sell against the OEM on engine LTSAs?**
A: You will not win on the engine OEM's own approved data — they have it first and they price it tighter. You win on response time (independent MROs commit faster AOG support in regions where the OEM is thin), workscope flexibility (OEM LTSAs often mandate full performance restoration when the customer would accept a lighter scope), parts strategy (independents accept used serviceable material and PMA parts where OEMs do not), and customer service (dedicated account team vs. OEM call center). Quantify the cost-per-flight-hour delta in writing — typically 8-14% lower than OEM equivalent — and back it with mean-time-between-removal data from comparable fleets.

**Q3: What MRO software do customers expect us to integrate with?**
A: AMOS (Swiss-AS, owned by Lufthansa Systems group), Trax, and Ramco Aviation cover the bulk of airline maintenance systems. CAMP and Aerotrac handle business aviation. Military programs run on GOLDesp, NTCSS, or program-specific maintenance management systems. Your CRM (typically Salesforce in MRO sales) needs API connections into the customer's system of record to pull tail number, flight hours, cycle counts, and induction forecasts. Operators without these integrations quote slower and lose to MROs who walk in with current asset data.

**Q4: How do we handle pricing escalation in multi-year contracts?**
A: Tie escalation to a published index, not internal cost. Common formulas: 40-50% labor (BLS aerospace labor index or local equivalent), 30-40% materials (CPI aerospace materials or PPI), 10-20% fixed. Cap annual escalation at 4-6% to keep customer comfort, and include a re-opener clause if the index moves more than 8% in any 24-month window. Avoid "cost-plus" language — airline procurement teams reject it on sight. The strongest contracts have transparent escalation that the customer's procurement can model independently.

**Q5: What does dispatch reliability have to do with sales?**
A: Everything. Airlines tie maintenance vendor performance to fleet dispatch reliability targets (typically 99.0-99.5% schedule completion). If your shop visits, line maintenance, or component repairs correlate with delays or cancellations, you become a quantified problem in the next QBR. The best sales teams pull dispatch reliability data from customers monthly, segment it by aircraft type and by MRO vendor, and walk into renewal meetings with proof of dispatch contribution. Vendors who cannot speak the dispatch reliability language are speaking a different language than the customer.

**Q6: How early do LTSA renewals need to start?**
A: 36 months minimum, 48 months ideal. LTSA decisions go through airline tech ops, finance, treasury, and often board approval. Incumbent advantage compresses inside 24 months because the customer's switching cost (data migration, parts pool transfer, approval re-validation) becomes a deterrent. If you are the incumbent, start renewal conversations 48 months out with fleet evolution discussions. If you are the challenger, start at 36 months with a benchmark study quantifying current contract performance against your offer.
