Aircraft Engines Intelligence
Commercial and business aircraft engine market analysis, technology comparisons, MRO constraints, lease pricing, and future propulsion signals.
Widebody propulsion
Widebody engine comparison
High-thrust engine availability, life-limited part status, shop visit timing, and OEM support materially influence aircraft acquisition, lease, and charter economics.
| Engine | Thrust | Applications | Market position |
|---|---|---|---|
| GE90-115B | 115,540 lbf | Boeing 777-300ER | Dominant engine on type with rising used pricing |
| GE9X | 134,300 lbf | Boeing 777X | Exclusive new-generation 777X engine |
| Rolls-Royce Trent XWB | 97,000 lbf | Airbus A350 | Exclusive A350 engine family |
| Engine Alliance GP7000 | 81,500 lbf | Airbus A380 | A380 fleet support and part-out economics |
Narrowbody economics
CFM56, V2500, LEAP, and geared turbofan intelligence
| Engine | Thrust | Applications | Efficiency note |
|---|---|---|---|
| CFM56-7B | 27,300 lbf | Boeing 737NG | Proven baseline with strong aftermarket depth |
| IAE V2500 | 33,000 lbf | A320ceo family | Competitive with CFM56 on mature fleets |
| LEAP-1A | 35,000 lbf | Airbus A320neo | Approx. 15% improvement versus CFM56-era technology |
| LEAP-1B | 29,300 lbf | Boeing 737 MAX | Approx. 14% improvement versus CFM56-era technology |
Engine deep dives
Market signals for acquisition and operations teams
GE90 engine family
Used pricing, LLP cycles, heavy shop visit exposure, and 777-300ER freight conversion demand influence acquisition timing.
CFM56 vs V2500
Narrowbody engine choice affects lease return conditions, shop slot risk, and residual market depth.
PT6 turboprop
King Air, Caravan, PC-12, and utility operators rely on PT6 supportability in remote and high-cycle operations.
MRO capacity remains a strategic constraint
Shop visit slots, parts availability, and OEM service bulletins are now central to aircraft transaction diligence. Engine condition can outweigh headline aircraft age in both commercial and business aviation markets.
