Airworthiness Directives; The Boeing Company Airplanes

FAA / Federal Register · 2023-28153

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 indicating that the oxygen supply tubing can become kinked when certain passenger service unit (PSU) oxygen panel assemblies are installed in the forward-most position of a center stow bin. This proposed AD would require a one- time inspection of the affected PSU oxygen panel assemblies and applicable on-condition actions. This proposed AD would also prohibit the installation of affected parts. The FAA is proposing this AD to address the unsafe condition on these products.
