Airworthiness Directives; Airbus Industrie Model A300, A300-600, and A310 Series Airplanes

Streszczenie

This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Industrie Model A300, A300-600, and A310 series airplanes, that requires inspections to detect cracks in the lower spar axis of the pylon between ribs 9 and 10, and repair, if necessary. This amendment is prompted by a report indicating that fatigue cracks have been found on the lower spar of the pylon. The actions specified by this AD are intended to prevent such fatigue cracking, which could result in reduced structural integrity of the lower spar of the pylon.
