Airworthiness Directive · Amendment 39-12208 · Airbus Model A330 Series Airplanes
Airbus Model A330 Series Airplanes
Model A330 series airplanes, certificated in any category; with serial numbers as listed in Airbus Service Bulletin A330-55A3026, dated June 23, 2000, or A330-55A3025, Revision 01, dated September 15, 2000.
This amendment adopts a new airworthiness directive (AD) that is applicable to certain Model A330 series airplanes. This action requires repetitive inspections of the spars, rib, and stringers in the vertical stabilizer spar box for failure of the bonds to the skin, and repair, if necessary. It also requires modification of the vertical stabilizer spar box by installation of fasteners to reinforce the bonds to the skin, which terminates the repetitive inspections. This action is prompted by issuance of mandatory continuing airworthiness information. This action is necessary to prevent failure of the bonds of the vertical stabilizer spar box to the skin, which could lead to reduced structural integrity of the spar box. It is intended to address the identified unsafe condition.
