FAA Orders Fix for Leaky Jet Engine Pumps
Published Date: 6/3/2026
Proposed Rule
Summary
The FAA wants to fix a fuel leak problem in certain General Electric GEnx engines by making airlines replace the main fuel pump with a safer part. This affects many big airplane engines and aims to keep flights safe and smooth. Comments on this plan are open until July 20, 2026, and swapping parts might cost some money but prevents bigger issues down the runway.
Analyzed Economic Effects
1 provisions identified: 0 benefits, 1 costs, 0 mixed.
Airlines Must Replace Defective Fuel Pumps
Operators of airplanes with the listed GE GEnx engines must remove from service certain main fuel pumps and replace them at the next engine shop visit after the AD's effective date to prevent a fuel leak that could cause an uncontrolled engine fire. The FAA estimates this proposed AD would affect 265 engines on U.S. registry; replacing with an overhauled pump is estimated at $25,337 per engine (8 work‑hours at $85/hour plus $24,657 parts), while a new main fuel pump would cost about $607,255. Comments on the proposal are due by July 20, 2026.
