The part number introduced in error is not certificated for the
IAE V2500-A5 engine installation and, if installed, may fail in
service.
Failure of the rear engine mount barrel nut could result in reduced
structural integrity of the rear engine mount and possible separation
of the engine from the airplane, and a consequent hazard to the
airplane and persons and property on the ground.
If I’m not too confused, the mentioned dates are also of interest :
October 17
Airbus has issued All Operator Telex A320-71A1045
October 20
The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Emergency Airworthiness Directive
November 26 (the day before Perpignan)
FAA AD issued
December 26
This AD becomes effective
An unsafe condition exists that requires the immediate adoption of
this AD.
These incorrect barrel nuts cannot withstand the engine loads
and must be replaced as soon as possible.
