Airworthiness Directives; The Boeing Company Airplanes

FAA / Federal Register · 2024-22802

The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 777-200, 777-200LR, 777-300ER, and 777F series airplanes. This AD was prompted by a report of potential latent failures of the lightning protection features for the engine fuel feed system. This AD requires repetitive inspections and bond resistance measurement of the bonding jumpers on the first fuel feed tube installed immediately forward of the wing front spar at each of the two engine locations, and applicable corrective actions. The FAA is issuing this AD to address the unsafe condition on these products.
