## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus SAS Model A350-941 and -1041 airplanes. This proposed AD was prompted by a report of incorrectly engaged lock washer tabs of the main landing gear (MLG) forward pintle bearing (FPB) at the forward face of the trunnion block. This proposed AD would require detailed inspections of the left-hand (LH) and right-hand (RH) side MLG FPB nuts and lock washer tabs, and depending on findings, accomplishment of repetitive detailed inspections or corrective actions, as specified in a European Union Aviation Safety Agency (EASA) AD, which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.
