Airworthiness Directives; The Boeing Company Airplanes

FAA / Federal Register · 2024-07562

The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 747-400F series airplanes. This proposed AD was prompted by a report that cap seals were not applied to certain fasteners in the fuel tanks during production. This proposed AD would require applying cap seals to certain fastener collars inside the fuel tanks. The FAA is proposing this AD to address the unsafe condition on these products.
