Airworthiness Directive · Amendment 39-18942 · Landing gear
Airbus Airplanes
Superseded. A later AD replaced this one: AD 2017-18-21. Comply with the one in force.
This AD applies to the airplanes identified in paragraphs (c)(1), (c)(2), (c)(3), and (c)(4) of this AD, certificated in any category, all manufacturer serial numbers.
(1) Airbus Model A318-111, -112, -121, and -122 airplanes.
(2) Airbus Model A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes.
(3) Airbus Model A320-211, -212, -214, -231, -232, and -233 airplanes.
(4) Airbus Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes.
We are adopting a new airworthiness directive (AD) for all Airbus Model A318 and A319 series airplanes; Model A320-211, -212, - 214, -231, -232, and -233 airplanes; and Model A321-111, -112, -131, - 211, -212, -213, -231, and -232 airplanes. This AD was prompted by an evaluation by the design approval holder (DAH), which indicates that the main landing gear (MLG) does not comply with certification specifications, which could result in a locking failure of the MLG side stay. This AD requires modification or replacement of certain MLG side stay assemblies. We are issuing this AD to address the unsafe condition on these products.
Within 120 months after the effective date of this AD, accomplish the action specified in paragraph (g)(1) or (g)(2) of this AD.
(1) Modify each MLG side stay assembly having a part number listed in figure 1 to paragraphs (g), (h), and (i) of this AD, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A320-32-1429, Revision 01, dated February 29, 2016, and the service information specified in paragraph (g)(1)(i) or (g)(1)(ii) of this AD, as applicable. The modification may be done “off wing,” provided the modified MLG is reinstalled on the airplane.
(i) For Model A318 series airplanes; Model A319 series airplanes; and Model A320-211, -212, -214, -231, -232, and -233 airplanes: Messier-Bugatti-Dowty Service Bulletin 200-32-315, dated April 24, 2015.
(ii) For Model A321 series airplanes: Messier-Bugatti-Dowty Service Bulletin 201-32-63, dated April 24, 2015.
(2) Replace the MLG side stay assembly with a side stay assembly that has been modified in accordance with paragraph (g)(1) of this AD. Do the replacement using a method approved by 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).
Note 1 to paragraph (g)(2) of this AD: Additional guidance for the replacement can be found in Chapter 32 of the Airbus A318/A319/A320/A321 Aircraft Maintenance Manual.

An airplane on which Airbus Modification (Mod) 156646, Airbus Mod 161202, or Airbus Mod 161346 has been embodied in production is not affected by the requirements of paragraph (g) of this AD, provided it is determined that no part having a part number identified in figure 1 to paragraphs (g), (h), and (i) of this AD, has been installed on that airplane since the date of issuance of the original certificate of airworthiness or the original export certificate of airworthiness. A review of the airplane maintenance records is acceptable to make this determination, provided that these records are accurate and can be relied upon to conclusively make that determination.
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.
