Unsafe condition

This AD was prompted by multiple reports of passenger service unit (PSU) oxygen generators shifting out of position within their associated PSU assemblies because of a retention failure. The FAA is issuing this AD to address PSU oxygen generators that might shift out of position within the PSU assembly and become non-functional. The unsafe condition, if not addressed, could result in an inability to provide supplemental oxygen to passengers during a depressurization event.

Affected ADs

None.
