CANCELLATION / REVISION: Not applicable. REASON: This AD results from reports that the pylon internal s hear pin was found cracked during a regular check. Further investigation revealed that the failure occurred due to hydrogen embrittlement. The ANAC is issuing this AD to prevent insufficient strength of the pylon to wing attachment, which in combination wi th an engine imbalance caused by a fan blade out could cause pylon to wing attachment failure and consequent engine separation.

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.
