FAA Proposes Requiring Fuel Pump Replacement on GE Engines for Boeing 787s

The Federal Aviation Administration has published a proposed safety rule that would require airlines to remove and replace specific main fuel pumps on General Electric GEnx engines. These engines power the Boeing 787 Dreamliner. The proposal follows a report of a Boeing 787 experiencing a fuel imbalance from a leak in the pump’s inlet housing. Investigators traced the leak to worn thrust bearing screws, which were caused by improper torque control during engine overhaul.

Why it matters: This is a standard aviation maintenance proposal, but it matters because fuel leaks in jet engines can lead to uncontrolled fires. The rule would force airlines to proactively replace vulnerable pumps before a failure occurs. If adopted, it would add a predictable maintenance step to engine overhaul schedules and shift repair costs to carriers and parts suppliers.

Who it affects

• Airlines operating Boeing 787 aircraft equipped with affected GE GEnx engines
