Airworthiness Directive · Amendment 39-9699 · Airbus Airplanes
Airbus Airplanes
This AD applies to Airbus A320-111, A320-211, A320-231.
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A320-111, -211, and -231 series airplanes, that requires repetitive high frequency eddy current inspections to detect cracks around the fasteners of the lower forward corners of the sliding window frames, and repair, if necessary. This amendment also requires the installation of a modification for each affected fastener hole, which terminates the repetitive inspections. This amendment is prompted by the results of full-scale fatigue tests which indicated that fatigue cracking occurred on the lower forward corner of the sliding window frames at frame 4. The actions specified by this AD are intended to prevent such fatigue cracking, which could result in rapid depressurization of the airplane.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
