Summary

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS Model A318-112 airplanes; Model A319-115, -132, - 133, -151N, -153N, and -171N airplanes; Model A320-211, -212, -214, - 231, -232, -251N, -252N, -253N, -271N, -272N, and -273N airplanes; and Model A321-112 airplanes. This proposed AD was prompted by a report that the fatigue life limit of the motoreductor installed on the on- board entrance stairs, is not demonstrated for the complete airplane design service goal (DSG). This proposed AD would require repetitive replacement of the motoreductor for on-board entrance stairs, and limit the installation of affected parts under certain conditions, 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.

The agency’s own summary, as published.
