ACTION: Final rule. SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. This 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 AD also prohibits the installation of engine inlets under certain conditions. The FAA is issuing this AD to address the unsafe condition on these products. DATES: This AD is effective September 24, 2024. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of September 24, 2024.

SUPPLEMENTARY INFORMATION: Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all The Boeing Company (Boeing) Model 787-8, 787-9, and 787-10 airplanes. The NPRM published in the Federal Register on February 20, 2024 (89 FR 12785). The NPRM was prompted by a report of heat damage on multiple engine inlets around the EAI duct within the inlet aft compartment. A subsequent investigation found that the seals between the inner and outer ducts and between the outer duct and the aft compartment were degraded or missing, which led to EAI air leaking into the aft compartment, exposing inle…
