Airworthiness Directives; Airbus SAS Airplanes
The FAA is superseding Airworthiness Directive (AD) 2019-05- 09, which applied to certain Airbus SAS Model A320-251N and -271N airplanes, and Model A321-253N airplanes. AD 2019-05-09 required repetitive detailed inspections of certain electrical harnesses for discrepancies, and corrective actions if necessary. AD 2019-05-09 also provided an optional terminating modification for the repetitive detailed inspections. This AD retains the actions of AD 2019-05-09, and adds a requirement for a terminating modification for the repetitive detailed inspections, as specified in a European Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD was prompted by reports of low clearance between the electrical harness and nearby hydraulic pipes in the inboard trailing edge of the wing. The FAA is issuing this AD to address the unsafe condition on these products.
