Unsafe Condition

Occurrences of main landing gear (MLG) trailing arm pins broken due to a fatigue mechanism induced by excessive torque applied during the assemblage of auxiliary door support attachment and consequent deformation of the MLG trailing arm axle. A broken pin can lead to loss of the MLG trailing arm axle, disconnecting the trailing arm from the main strut, which affects the airplane controllability on ground.

Required Actions

Inspect for cracks in the MLG trailing arm pin. Replace the MLG trailing arm pin with a serviceable pin if necessary. Modify the MLG auxiliary door mounting support.
