Airworthiness Directive · Amendment 39-9274 · Airbus Airplanes
Airbus Airplanes
This AD applies to Airbus A340-211, A340-212, A340-311, A340-312.
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 A340 series airplanes. This action requires installation of a reinforcement modification on the structure of the left- and right-hand cowls of the thrust reversers. This amendment is prompted by the results of a full-scale fatigue test, conducted by the manufacturer, which indicated that fatigue cracks can occur between the 3 and 9 o'clock thrust reverser beams and the forward frame/"J"-ring. The actions specified in this AD are intended to prevent loss of the use of the thrust reversers as a result of the problems associated with fatigue cracking in their cowling structure.
