The world’s biggest lessor, AerCap, is concerned about the reliability of the latest generation of engines. Powerplants need to be removed from the wing for maintenance, repair, and overhaul much sooner than expected. In the current environment of supply chain problems, this is most unwelcome, AerCap remarked in its HY1 2022 earnings release. AerCap concerned about new-engine reliability.

Reliability issues have been well-reported for various engines in the past few years. They include the Rolls-Royce Trent 1000 and 1000 TEN, the General Electric GEnx, the Pratt & Whitney Geared Turbofan, and the CFM LEAP. The Trent XWB has been less prone to durability problems. It was believed that OEMs had addressed these issues with costly redesigns and updates, but apparently, AerCap is noting something different.
