Summary
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS Model A321-251NX, -252NX, -253NX, -271NX, and -272NX airplanes. This proposed AD was prompted by discovery of two bushes that had migrated on the latch shaft of an emergency overwing exit door (OWED) during accomplishment of an inspection on an in-service airplane. This proposed AD would require repetitive detailed inspections (DETs) of the affected parts and, in case of discrepancies, modification of the affected parts, and would prohibit the installation of affected parts, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.
