What is the problem with the engine on the 737 Max?

Excessive heat buildup can cause overheat of the engine inlet inner barrel beyond the material design limit, resulting in failure of the engine inlet inner barrel and severe engine inlet cowl damage. There have been no reports of in-service failures of the engine inlet inner barrel to date, the FAA said.



In 2026, the primary unresolved "engine-related" issue for the Boeing 737 MAX involves the Engine Anti-Ice (EAI) system. This system has been under intense scrutiny because, if left on in dry air for more than five minutes, it can potentially cause the engine inlet cowls to overheat and break apart, leading to catastrophic engine damage. While Boeing has committed to a permanent hardware fix, the certification for this modification has pushed the approval of the 737 MAX 7 and MAX 10 variants into 2026. Current operators of the MAX 8 and 9 must follow strict pilot directives to limit EAI usage. Separately, the CFM LEAP-1B engines have faced investigation regarding a Load Reduction Device (LRD) that activates during fan damage; in some cases, its activation caused oil leaks and smoke to enter the cockpit, prompting ongoing software and hardware refinements under FAA and EASA oversight.
