Airworthiness Directive · Amendment 39-9975 · Airbus Model A300 Series Airplanes
Airbus Model A300 Series Airplanes
Model A300 airplanes having serial numbers 001 through 0156, inclusive, certificated in any category.
This amendment adopts a new airworthiness directive (AD) that is applicable to certain Airbus Model A300 series airplanes. It requires a one-time template inspection of the rear pressure bulkhead to detect dents; repetitive eddy current inspections of dents greater than a certain depth to detect cracking; and repair, if necessary. This amendment is prompted by a report indicating that cracking has been found in the vicinity of a dent in the rear pressure bulkhead of one airplane. The actions specified by this amendment are intended to prevent fatigue cracking resulting from a dent in the rear pressure bulkhead; that condition, if not corrected, could reduce the structural integrity of the bulkhead and, consequently, lead to rapid depressurization of the airplane.
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.
