Subject
- It was found the occurrence of an engine in-flight shutdown caused by the LPCV P/N 1001447-3 failing to close due to excessive wear, which leads to the concern that such fault may be present in both engines of a given aircraft. It has been also found cracks in the LPCV P/N 1001447-4 due
to low cycle fatigue. These cracks may be present in both LPCV of the same aircraft and may cause an in flight shut down (IFSD) in both engines of the aircraft.
Since this condition may occur in other airplanes of the same type and affects flight safety, a corrective action is required. Thus, sufficient reason exists to request compliance with this AD in the indicated time limit.
