Models named: A350-941. Read the applicability below — it usually turns on serial or part numbers too.

Applicability*9

This AD applies to Airbus Model A350-941 airplanes, certificated in any category, manufacturer serial numbers (MSN) 0006 to 0040 inclusive, except MSN 0025, 0032, 0033, 0036, 0038, and 0039.

Compliance

Comply with this AD within the compliance times specified, unless already done.

Required actions

Before exceeding 1,880 flight cycles since first flight of the airplane, accomplish a detailed inspection for nonconformance (incorrect retaining pins, i.e., those having a gap between the retaining pin and the forward surface of the trunnion block) of the four retaining pins installed in the MLGSS trunnion block, left- and right-hand sides and related investigative actions, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A350-57-P011, dated May 17, 2017.

Unsafe condition

This AD was prompted by a determination that short retaining pins may have been installed at the incorrect location of the main landing gear support structure (MLGSS) forward pintle. We are issuing this AD to address incorrect retaining pin installations, which could lead to premature failure of the retaining pin and subsequent fuse pin migration and disconnection, and could ultimately lead to main landing gear collapse and possible damage to the airplane.

Affected ADs

None.
