Airworthiness Directive · Amendment 39-12382 · Airbus Model A330 Series Airplanes
Airbus Model A330 Series Airplanes
Superseded. A later AD replaced this one: AD 2020-22-09. Comply with the one in force.
Model A330 airplanes, serial numbers 301, 321, 322, 323, 341, 342, and 343, certificated in any category; except airplanes on which Airbus Industrie Modification 46636 has been accomplished in production or which have been modified in service in accordance with Airbus Service Bulletin A330-53-3090, dated March 9, 1999; Revision 01, dated July 6, 1999; or Revision 02, dated January 9, 2001.
This amendment adopts a new airworthiness directive (AD), applicable to certain Model A330 series airplanes. This action requires a one-time roto-test inspection of fastener holes of certain fuselage joints for cracks and reinforcement of the fuselage between frames 31 and 37.1. If cracks are detected, this action requires a follow-up high frequency eddy current (HFEC) inspection and repair. This action is necessary to prevent fatigue cracking of the fuselage longitudinal buttstrap, which could result in reduced structural integrity of the fuselage. This action is intended to address the identified unsafe condition.
