Summary
The FAA proposes to supersede Airworthiness Directive (AD) 2019-05-09, which applies to certain Airbus SAS Model A320-251N and - 271N airplanes, and Model A321-253N airplanes. AD 2019-05-09 requires repetitive detailed inspections of certain electrical harnesses for discrepancies and corrective actions, if necessary. AD 2019-05-09 also provides an optional terminating modification for the repetitive detailed inspections. Since we issued AD 2019-05-09, the FAA has determined that it is necessary to require the terminating modification. This proposed AD would retain the actions of AD 2019-05- 09 and add a requirement for a terminating modification for the repetitive inspections, as specified in an European Aviation Safety Agency (EASA) AD, which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.
