Engine Overview
The LEAP family powers Airbus A320neo, Boeing 737 MAX and COMAC C919 aircraft.
| Engine Family | LEAP |
|---|---|
| Variants | LEAP-1A / -1B / -1C |
| Applications | A320neo / 737 MAX / C919 |
| Technology | Advanced high-bypass turbofan |
| Market | Current-generation narrowbody |
| Support Focus | Engines, modules, LLPs, rotables |
Variants & Aircraft Applications
Commercial application and configuration vary by engine rating and aircraft model.
| Engine Variant | Primary Application |
|---|---|
| LEAP-1A | Airbus A320neo family |
| LEAP-1B | Boeing 737 MAX family |
| LEAP-1C | COMAC C919 |
Final applicability must be verified against current approved aircraft and engine documentation.
Global Fleet Footprint
As of April 2026, CFM reports 155 LEAP operators overall, with more than 104 million engine flight hours. LEAP-1A had 92 operators, LEAP-1B 77 and LEAP-1C 3.
Fleet/operator counts evolve; use current OEM and operator records for transaction-level verification.
Representative LEAP LLP P/Ns
| Module | P/N | Description |
|---|---|---|
| Fan | 362-040-010-0 | Fan Disk |
| Fan | 362-040-011-0 | Fan Disk |
Reference only. LLP applicability and certified life are configuration/revision specific and must be verified against current approved records.
Maintenance & Shop-Visit Planning
| Performance | Trend EGT margin, vibration, oil-system health and digital engine data. |
|---|---|
| Environment | Hot-and-harsh and dusty operations can materially affect maintenance planning. |
| Supply chain | New-generation material availability and shop capacity can drive turnaround time. |
| Workscope | Early-life fleets often focus on targeted module repair, hardware upgrades and restoration strategy. |
There is no single universal overhaul interval applicable to every engine in this family.
Indicative Shop-Visit Cost Context
Public LEAP shop-visit pricing remains highly event-specific and is changing rapidly with fleet maturity, parts availability and workscope. For budgeting, module condition, hardware standard, LLP status and MRO slot availability are more useful than a single generic overhaul figure.
| Main drivers | Workscope, LLP status, hot-section material, repairability, USM availability, labor, shop capacity and engine configuration. |
|---|---|
| Commercial check | Compare planned shop-visit investment with current engine and green-time replacement value. |

Commonly Sourced LEAP Material
Typical LEAP sourcing demand includes fan and compressor hardware, fuel and oil accessories, pumps, valves, actuators, sensors, bearings, module material and traceable serviceable components. Exact applicability must be verified by engine model and configuration.
CFM Gate's RFQ/OFFER database is not yet reliably tagged by engine family, so this page does not publish an artificial “top P/N” ranking.
