AD NUMBER: 2017-13-07

PRODUCT: All Airbus Model A319, A320, and A321 series airplanes.

ACTION: Final Rule.

SUMMARY: This AD was prompted by a report that a main landing gear (MLG) door could not be closed due to rupture of the actuator fitting.

This AD requires repetitive inspections for cracking of the MLG door actuator fitting and its components, and corrective actions if necessary.

This AD also requires eventual replacement of all affected MLG door actuator fittings with new monoblock fittings, which would terminate the repetitive inspections. We are issuing this AD to address the unsafe condition on these products.

The FAA estimates that this AD affects 71 airplanes of U.S. registry. It further estimates that it takes about 136 work-hours per product to comply with the requirements of this AD.

The average labor rate is $85 per work-hour. Required parts will cost about $6,258 per product.

Based on these figures, it is estimated the cost for the actions required by this AD on U.S. operators to be $1,265,078, or $17,818 per product.

DATES: This AD is effective August 9, 2017.
