Airworthiness Directives; The Boeing Company Airplanes
Abstract
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 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 AD requires a one-time inspection of the affected PSU oxygen panel assemblies and applicable on-condition actions. This AD also prohibits the installation of affected parts. The FAA is issuing this AD to address the unsafe condition on these products.
Applicability
Aircraft makes and models this AD applies to, sorted by US-registered fleet size.
