Airworthiness Directives; Airbus Model A300-600 Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to all Airbus Model A300-600 series airplanes, that requires an inspection to detect cracks of certain attachment holes; and installation of a new fastener and follow-on inspections or repair, if necessary. This amendment is prompted by reports of fatigue cracking found on the forward fitting of frame 47 at the level of the last fastener of the external angle fitting. The actions specified by this AD are intended to prevent such fatigue cracking, which could result in reduced structural integrity of the airframe.
