Abstract
The FAA is adopting a new airworthiness directive (AD) for certain Aerospace & Defense Oxygen Systems SaS portable breathing equipment (PBE). This AD was prompted by reports of occurrences of PBE not delivering oxygen once donned. This AD requires replacing affected PBE and prohibits the installation of affected PBE. The FAA is issuing this AD to address the unsafe condition on these products.
