Airworthiness Directives; The Boeing Company Airplanes

FAA / Federal Register · 2024-03254

The FAA proposes to adopt a new airworthiness directive (AD) for all The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. This proposed AD was prompted by a report of heat damage on multiple engine inlets around the engine anti-ice (EAI) duct within the inlet aft compartment. This proposed AD would require doing a records check and updating the operator's existing minimum equipment list (MEL), inspecting the left and right engine inlet cowl assembly for signs of heat damage around the EAI duct, installing or replacing the EAI duct seals, repairing any damage, and replacing the engine inlet if necessary. This proposed AD would also prohibit the installation of engine inlets under certain conditions. The FAA is proposing this AD to address the unsafe condition on these products.
