Airworthiness Directive · Amendment 39-22776 · Oxygen
The Boeing Company Airplanes
This AD applies to all The Boeing Company Model 737-8, 737-9, and 737-8200 airplanes and Model 737-700, -800, and -900ER series airplanes, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 737-8, 737-9, and 737-8200 airplanes and Model 737-700, -800, and -900ER series airplanes. 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. This AD requires a general visual inspection of the PSU oxygen generator installation to determine the configuration of the thermal pads of the retention straps 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.
