Airworthiness Directive · Amendment 39-19306 · Powerplant
Airbus Airplanes
This AD applies to all Airbus Model A318-111 and -112 airplanes; Model A319-111, -112, -113, -114, and -115 airplanes; Model A320-211, -212, -214, and -216 airplanes; and Model A321-111, -112, -211, -212, and -213 airplanes; certificated in any category.
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, -214, and -216 airplanes; and Model A321-111, -112, -211, -212, and -213 airplanes. This AD was prompted by a review of maintenance instructions for a blend repair of the snout diameter of the main beam assembly of the forward engine mount that would create an excessive gap between the bearing mono-ball and the snout. This AD requires modifying the main beam assembly of the forward engine mount. We are issuing this AD to address the unsafe condition on these products.
For the purposes of this AD: An “affected main beam” is any main beam assembly of the forward engine mount, part number (P/N) 642-2006-501 or P/N 642-2006-503, identified in paragraph (g)(1) or (g)(2) of this AD.
(1) Any part for which no maintenance records are available to confirm the part has never been repaired.
(2) Any part that was repaired as specified in Repair 10, of Goodrich Aerospace Component Maintenance Manual (CMM) 71-21-08, Revisions 1 through 46, except for parts identified in paragraphs (g)(2)(i), (g)(2)(ii), and (g)(2)(iii) of this AD.
(i) Any part on which a qualifying inspection identified in paragraph (h) of this AD has been done and there were no findings (the inspection was passed).
(ii) Any part on which a qualifying inspection identified in paragraph (h) of this AD has been done and that part has been repaired as specified in Goodrich Aerospace Service Bulletin RA32071-159.
(iii) Any part that has been repaired in accordance with other instructions approved by the Manager, International Section, Transport Standards Branch, FAA; or the European Aviation Safety Agency (EASA); or Airbus's EASA Design Organization Approval (DOA).
For the purposes of this AD: “A qualifying inspection” is an inspection done as specified in Goodrich Aerospace Service Bulletin RA32071-159; or for CFM56-5B engines, an inspection done as specified in Repair 10 of Goodrich Aerospace CMM 71-21-08, Revision 47; or for CFM56-5A engines, an inspection done as specified in Repair 21 of Goodrich Aerospace CMM 71-21-06, Revision 59.
For the purposes of this AD: “Group 1 airplanes” are airplanes on which an affected main beam has been installed as of the effective date of this AD. “Group 2 airplanes” are airplanes on which an affected main beam has not been installed as of the effective date of this AD; this includes airplanes with an original certificate of airworthiness or original export certificate of airworthiness that was issued after the effective date of this AD.
For Group 1 airplanes as identified in paragraph (i) of this AD: At the earliest of the compliance times specified in paragraphs (j)(1), (j)(2), and (j)(3) of this AD, modify, including doing all applicable inspections and corrective actions, for each affected main beam identified in paragraph (g) of this AD, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A320-71-1065, Revision 01, dated July 28, 2017; or Airbus Service Bulletin A320-71-1066, dated December 1, 2016; as applicable; except as required by paragraph (k) of this AD.
(1) Within 48 months after the effective date of this AD.
(2) Within 10,000 flight cycles after the effective date of this AD.
(3) Within 15,000 flight hours after the effective date of this AD.
Where Airbus Service Bulletin A320-71-1065, Revision 01, dated July 28, 2017, specifies to contact a manufacturer for appropriate action, and specifies that action as “RC” (Required for Compliance): Before further flight, accomplish corrective actions in accordance with the procedures specified in paragraph (n)(2) of 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.
