Airworthiness Directive · Amendment 39-10544 · Airbus Model A310 and A300-600 Series Airplanes
Airbus Model A310 and A300-600 Series Airplanes
Model A310 and A300-600 series airplanes, equipped with Pratt & Whitney Model JT9D-7R4D1, JT9D-7R4E1, JT9D- 7R4H1, PW4151, PW4156A, or PW4158 engines; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A310 and A300-600 series airplanes, that requires a visual inspection to detect cracks in the aft mount beam assembly of the engine; and replacement of any cracked beam with a new beam or beam assembly. This amendment also requires a fluorescent penetrant inspection to detect cracks in the aft mount beam assembly of the engine, and various follow-on actions. This amendment is prompted by reports indicating that, apparently due to manufacturing defects during the forging process, cracking was found in two engine aft mount beams. The actions specified by this AD are intended to detect and correct such cracking, which could result in reduced structural integrity of the aft mount beam assembly of the engine.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
