Airworthiness Directive · Amendment 39-10851 · Airbus Model A320 Series Airplanes
Airbus Model A320 Series Airplanes
Superseded. A later AD replaced this one: AD 2004-14-09. Comply with the one in force.
Model A320 series airplanes on which Airbus Modification 22418 (reference Airbus Service Bulletin A320-57-1043, Revision 02, dated May 14, 1997) has not been accomplished, certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A320 series airplanes, that requires repetitive inspections to detect fatigue cracking of the lower surface panel on the wing center box; and repair, if necessary. This amendment also requires modification of the lower surface panel on the wing center box, which constitutes terminating action for the repetitive inspections. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent fatigue cracking of the lower surface panel on the wing center box, which could result in reduced structural integrity of the airplane.
