Airworthiness Directive · Amendment 39-18434 · Power plant
Airbus Airplanes
This AD applies to the Airbus airplanes, certificated in any category, identified in paragraphs (c)(1), (c)(2), and (c)(3) of this AD, all manufacturer serial numbers.
(1) Model A319-131, -132, and -133 airplanes.
(2) Model A320-232 and -233 airplanes.
(3) Model A321-131, -231, and -232 airplanes.
We are adopting a new airworthiness directive (AD) for all Airbus Model A319-131, -132, and -133 airplanes; Model A320-232 and - 233 airplanes; and Model A321-131, -231, and -232 airplanes. This AD was prompted by reports of forward engine mount attachment pins that were manufactured from discrepant raw material. This AD requires identification and replacement of affected forward engine mount attachment pins. We are issuing this AD to prevent failure of a forward engine mount attachment pin, possible loss of an engine in-flight, and consequent reduced controllability of the airplane.
Except as provided by paragraph (i) of this AD, at the earliest of the times specified in paragraphs (g)(1) through (g)(4) of this AD: For each engine, identify the part number of the forward engine mount, and the part number and serial number of the attachment pin for that forward engine mount, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A320-71-1064, Revision 01, dated April 1, 2015; and Goodrich Aerostructures Service Bulletin V2500-NAC-71-0323, Revision 01, dated January 28, 2015. A review of airplane maintenance records is acceptable in lieu of this identification if the part number of the forward engine mount, and the part number and serial number of the attachment pin for that forward engine mount, can be conclusively determined from that review. If any part number of the forward engine mount, or part number or serial number of the attachment pins for the forward engine mount, cannot be identified: At the earliest of the times specified in paragraphs (g)(1) through (g)(4) of this AD, contact the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA; or the European Aviation Safety Agency (EASA); or Airbus's EASA Design Organization Approval (DOA), for identification information.
(1) Within 24 months after the effective date of this AD.
(2) At the next engine removal after the effective date of this AD.
(3) Within 7,500 flight hours after the effective date of this AD.
(4) Within 5,000 flight cycles after the effective date of this AD.
If, during any identification required by paragraph (g) of this AD, a forward engine mount having part number (P/N) 745-2010-503 is found, and the attachment pin has P/N 740-2022-501 with any serial number that is included in figure 1 to paragraphs (h) and (j) of this AD: At the earliest of the times specified in paragraphs (g)(1) through (g)(4) of this AD, replace the affected attachment pin with a serviceable part having a part number other than P/N 740-2022-501, and having a serial number that is not identified in figure 1 to paragraphs (h) and (j) of this AD, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A320-71-1064, Revision 01, dated April 1, 2015; and Goodrich Aerostructures Service Bulletin V2500-NAC-71-0323, Revision 01, dated January 28, 2015.
