## Summary

We propose to adopt a new airworthiness directive (AD) for all Airbus Model A318, A319, A320, and A321 series airplanes. This proposed AD was prompted by a determination that certain special washers used in the retraction jack anchorage fitting bearing installation in the main landing gear (MLG) were incorrectly manufactured. This proposed AD would require an inspection of the left-hand (LH) and right-hand (RH) MLG retraction jack anchorage fitting bearing assemblies to verify that the special washer is seated correctly, and related investigative and corrective actions if necessary. We are proposing this AD to detect and correct installation of incorrectly manufactured special washers, which could lead to a local stress concentration resulting in possible reduction of the fatigue life of the jack fitting, and consequent reduction of the structural integrity of the affected MLG.
