Description
The FAA proposes a new airworthiness directive (AD) for certain General Electric Company (GE) engine models due to a reported fuel leak from a worn main fuel pump inlet housing. The AD would require removal from service of the main fuel pump and replacement with an eligible part to prevent an uncontrolled engine fire and damage to the airplane. This proposed rulemaking invites comments until July 20, 2026, and affects engines installed on U.S. registered airplanes.
