AD NUMBER: 2016-19-10

PRODUCT: Certain Airbus Model A300 series airplanes; Model A300 B4-600, B4-600R, F4-600R series airplanes, and Model A300 C4-605R Variant F airplanes (collectively called Model A300-600 series airplanes); and Model A310 series airplanes.

ACTION: Final Rule

SUMMARY:  The FAA is superseding Airworthiness Directive (AD) 2000-10-18 for the aircraft listed above.

AD 2000-10-18 required repetitive inspections to detect cracks in the lower spar of the engine pylons between ribs 6 and 7, and repair if necessary.

This new AD reduces the compliance times for the initial inspection and the repetitive intervals. This AD was prompted by the determination that the compliance times for the initial inspection and the repetitive intervals must be reduced to allow timely detection of cracks in the engine pylon's lower spar between ribs 6 and 7.

The FAA is issuing this AD to detect and correct fatigue cracking, which could result in reduced structural integrity of the engine pylon's lower spar, and possible separation of the engine from the airplane.

DATES: This AD is effective October 31, 2016.
