Airworthiness Directive · Amendment 39-11412 · Airbus Model A330 and A340 Series Airplanes
Airbus Model A330 and A340 Series Airplanes
Superseded. A later AD replaced this one: AD 2018-09-02. Comply with the one in force.
Model A330 and A340 series airplanes; except those airplanes on which Airbus Modification 42605, or Airbus Service Bulletin A330-53-3019 (for Model A330 series airplanes) or A340-53-4028 (for Model A340 series airplanes) has been accomplished; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A330 and A340 series airplanes, that requires repetitive detailed visual inspections to detect cracking of the vertical flange of the inboard Z-stiffeners of the centerline panel of the fuselage belly fairing; and corrective actions, if necessary. This amendment also provides for 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 vertical flange of the inboard Z-stiffeners of the centerline panel of the fuselage belly fairing, which could result in reduced structural integrity of the belly fairing.
