(1) Airbus Model A318-111 and -112 airplanes.
(2) Airbus Model A319-111, -112, -113, -114, and -115 airplanes.
(3) Airbus Model A320-211, -212, and -214 airplanes.

We are adopting a new airworthiness directive (AD) for all Airbus Model A318-111, and -112 airplanes; Model A319-111, -112, -113, -114, and -115 airplanes; Model A320-211, -212 and -214 airplanes; and Model A321-111, -112, -211, -212, and -213 airplanes. This AD was prompted by a report of a production quality deficiency on the inner retainer installed on link assemblies of the aft engine mount, which could result in failure of the retainer. This AD requires an inspection for, and replacement of, all non-conforming aft engine mount retainers. We are issuing this AD to address the unsafe condition on these products.
Within 2 months after the effective date of this AD, do an inspection to determine if any non-compliant aft engine mount inner retainer is installed; and within 2 months after the effective date of this AD, replace each part that meets any of the criteria specified in paragraph (g)(1), (g)(2), or (g)(3) of this AD. Do the inspection in accordance with the service information specified in paragraph (h)(1) of this AD. Do the replacement in accordance with the service information specified in paragraph (h)(1), (h)(2), or (h)(3) of this AD. A review of airplane maintenance records is acceptable in lieu of the inspection required by this paragraph, if it can be conclusively determined that there are no non-compliant aft engine mount inner retainers installed on the airplane.
(1) An aft engine mount inner retainer from an aft engine mount having a serial number listed in table 1 of Airbus Alert Operators Transmission (AOT) A71N011-15, Rev 01, dated February 1, 2016.
(2) An aft engine mount inner retainer installed on an airplane between the first flight of the airplane or March 1, 2015 (whichever occurs later), and the effective date of this AD, and that can be identified by a purchase order (PO) listed in table 2 of Airbus AOT A71N011-15, Rev 01, dated February 1, 2016.
(3) An aft engine mount inner retainer installed on an airplane between the first flight of the airplane or March 1, 2015 (whichever occurs later), and the effective date of this AD, and that cannot be identified by a PO.
Accomplish the replacement required by paragraph (g) of this AD in accordance with the service information specified in paragraph (h)(1), (h)(2), or (h)(3) of this AD.
(1) The Accomplishment Instructions of Airbus Service Bulletin A320-71-1070, dated November 23, 2015.
(2) Paragraph 4.2.2, “Requirements,” of Airbus AOT A71N011-15, Revision 01, dated February 1, 2016.
(3) The Accomplishment Instructions of Goodrich Service Bulletin RA32071-165, dated October 9, 2015.
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.
