Unsafe Condition
An occurrence was reported where, during pushback of an aeroplane, a main landing gear (MLG) sliding tube axle fractured. Investigation results revealed an incorrect accomplishment of a repair at the previous overhaul of the chromium plated axle diameters, which resulted in the overheat damage to the sliding tube axle journal(s). This initiated a crack which, under fatigue effects, led to fracture of the MLG sliding tube axle. A limited number of MLG sliding tubes has been identified that may have been subject to the same incorrect repair.

Required Actions
A repetitive magnetic particle inspection (MPI) of affected MLG sliding tubes for discrepancies; a one-time Barkhausen noise inspection (BNI) or alternative non-destructive test (NDT) inspection, and a detailed visual inspection of affected MLG sliding tube axles for discrepancies; and corrective actions if necessary, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. Accomplishing the BNI and applicable corrective actions, or replacing the affected parts, constitutes terminating action for the repetitive MPI.
