FAA directive requires inspection of Boeing oxygen generators on certain planes

The Federal Aviation Administration , or FAA, is adopting a new airworthiness directive, or AD, for all The Boeing Company Model 737-8, 737-9, and 737-8200 airplanes and Model 737-700, -800, and -900ER series airplanes, the agency stated in a notice posted in the Federal Register. “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,” the notice stated.
