Description

The FAA proposes a new airworthiness directive (AD) for certain Airbus SAS Model A350-941 airplanes due to a missing main landing gear (MLG) brake rod center pin nut sub-assembly found during inspection. The AD would require inspections of the MLG brake rod center pin nut, lock ring, end plate, and applicable corrective actions depending on airplane configuration. Additional work may be required for certain airplanes to address this unsafe condition and prevent potential damage or injury.
