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
