Unsafe Condition
defects on the piston hole associated with the O<NF>2<INF> saver function that may prevent efficient deactivation of the O<NF>2<INF> saver function and a determination that the airplane flight manual (AFM) amendment required by AD 2021-19-20 may not be sufficient to mitigate the risk of failed deactivation of the O<NF>2<INF> saver function.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
amend the existing AFM to incorporate a specific check to ensure that the O<NF>2<INF> saver function is not activated and an operating limitation to prevent use of the O<NF>2<INF> saver function; and for mechanically deactivating the O<NF>2<INF> saver function of the affected parts (Safran flightcrew oxygen masks having part number MLD40-45-005 and serial number B150451 through B172005 inclusive without the letter ``R'' after the serial number).
