ACTION: Final rule; request for comments.

SUMMARY: This AD was prompted by a report of the fracture of a main landing gear (MLG) sliding tube axle, and an investigation that determined the cause to be an incorrect repair.

This AD requires 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.

DATES: This AD becomes effective August 23, 2019. Comments must be received by September 23, 2019.

COST: The FAA estimates that this AD affects 1 airplane of U.S. registry. Operators may incur the following costs in order to comply with this AD:

• Labor: Up to 14 work-hours × $85 per hour = Up to $1,190 per aircraft
