Airworthiness Directive · Amendment 39-21533 · Powerplant
Airbus SAS Airplanes
This AD applies to all Airbus SAS Model A319-171N airplanes, Model A320-271N, -272N, and -273N airplanes, and Model A321-271N, -272N, -271NX, and -272NX airplanes, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A319-171N airplanes, Model A320-271N, -272N, and -273N airplanes, and Model A321-271N, -272N, -271NX, and -272NX airplanes. This AD was prompted by a report indicating that during a full scale fatigue test of the forward engine mounts, premature wear was identified on the forward engine mount shackle assemblies; in addition, during bearing replacement, the bearing lock washer was found broken. This AD requires replacing any forward engine mount shackle assemblies having a certain part number with a serviceable part, and re- identifying the engine mount, or replacing any forward engine mount assemblies having a certain part number, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, European Union Aviation Safety Agency (EASA) AD 2020-0250, dated November 11, 2020 (EASA AD 2020-0250).
(1) Where EASA AD 2020-0250 refers to its effective date, this AD requires using the effective date of this AD.
(2) The “Remarks” section of EASA AD 2020-0250 does not apply to this AD.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
