Airworthiness Directives; Airbus SAS Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD) 2020-06-18, which applies to all Airbus SAS Model A318 series airplanes; A319 series airplanes; A320-211, -212, -214, -216, -231, - 232, -233, -251N, -252N, -253N, -271N, -272N, and -273N airplanes; and A321 series airplanes. AD 2020-06-18 requires replacement of affected trimmable horizontal stabilizer actuators (THSAs) with serviceable THSAs. Since the FAA issued AD 2020-06-18, a new Airbus airplane model (A321-253NY) has been certified, on which affected parts could be installed in service. This proposed AD would continue to require the actions in AD 2020-06-18, would revise the applicability to include Model A321-253NY airplanes, 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.

DATES: The FAA must receive comments on this proposed AD by July 3, 2025.
