What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) privacy data omitted distribution: AFS-300, GL-23, AEA-230 #2 engine oil pressure was dropping in cruise. The crew reduced power as per check list and pressure continue to drop. The engine was shut down and the aircraft landed at roc. Engine oil was found on the outside of the #2 engine cowling and right side of the tail. It was determined that the "o" ring on the oil filter cover was nicked during installation and was the cause of the leak.
