Willis Lease and CFM Launch CFM56 Life-Extension Program With Initial Engines Inducted
The collaboration uses OEM-supplied material with in-shop core restoration to keep CFM56-5B/7B units on wing longer at controlled cost.
Overview
- Willis Lease Finance Corporation introduced an industry-first program with CFM International focused on extending service life for CFM56-5B and CFM56-7B engines.
- The approach restores core components instead of fully disassembling engines, targeting longer time on wing and lower lifecycle expense.
- WLFC says it is the first commercial engine lessor to partner with the OEM on this type of initiative for these engine models.
- The company has already inducted an initial group of engines and plans to expand participation across additional assets over time.
- CFM said WLFC will receive OEM material support to maintain reliability, and WLFC separately scheduled its Q4 and full-year 2025 results and call for March 10, 2026.
