Airworthiness Directive · Amendment 39-10742 · Airbus Model A320 Series Airplanes
Airbus Model A320 Series Airplanes
Superseded. A later AD replaced this one: AD 2016-01-11. Comply with the one in force.
Model A320 series airplanes on which Airbus Modification 21290 (reference Airbus Service Bulletin A320-57-1017, Revision 01, dated March 17, 1997) has not been installed, 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 front spar vertical stringers on the wings; and repair, if necessary. This amendment also provides for an optional 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 detect and correct fatigue cracking of the front spar vertical stringers on the wings, which could result in reduced structural integrity of the airframe.
