AD 2021-23-05 Retains The Requirements Of AD 2021-18-08, With Clarified Instructions

The FAA is superseding Airworthiness Directive (AD) 2021-18-08, which applied to all Airbus SAS Model A319-171N airplanes; Model A320-271N, -272N, and -273N airplanes; and Model A321-271N, -272N, -271NX, and -272NX airplanes.

AD 2021-18-08 required repetitive inspections of the pylon/engine interface rods for damage, and applicable corrective actions, as specified in European Union Aviation Safety Agency (EASA) AD 2021-0177. AD 2021-18-08 also provided for limited installation of affected parts under certain conditions. Since the FAA issued AD 2021-18-08, operators reported that the requirements of EASA AD 2021-0177 were unclear. This AD retains the requirements of AD 2021-18-08, with clarified instructions, as specified in an EASA AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products. This AD is effective November 23, 2021.
