Abstract
This amendment adopts a new airworthiness directive (AD) that applies to any aircraft equipped with Puritan-Bennett Aero Systems Company (Puritan-Bennett) C351-2000 series passenger oxygen masks and portable oxygen masks. This AD requires inspecting the passenger and portable oxygen masks for tears around the face cushion adjacent to the inner mask housing, and replacing or repairing any torn passenger or portable oxygen mask. This AD is the result of reports received from three airplane manufacturers of defective oxygen masks. The actions specified by this AD are intended to prevent reduced oxygen consumption when passengers are required to use defective oxygen masks, which could result in passenger injury.
