Airworthiness Directive · Amendment 39-10586 · Airbus Model A320 Series Airplanes
Airbus Model A320 Series Airplanes
Model A320 series airplanes, on which Airbus Modification 20941 (reference Airbus Service Bulletin A320-53-1011, dated December 9, 1994) 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 on the connecting angle between frame 56 and the right-hand frame support at stringer 38; and replacement of the connecting angle, 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 on the connecting angle, which could result in reduced structural integrity of the airplane.
