Southwest Airlines flight WN438, a Boeing 737-300, experienced a failure of the No. 2 engine, a CFM CFM56-3B1 while climbing through FL250 to FL330. The flight crew reported feeling severe vibration, pulled both throttles back to idle, declared an emergency, and started an air turn back to Love Field (DAL), Dallas, TX. While heading back to DAL, the pilot reported seeing the following cockpit warnings: a No. 2 constant speed drive (CSD) low oil pressure, No. 2 engine low oil pressure, No. 2 generator bus OFF, No. 2 pack trip OFF lights, and No. 2 engine vibration meter at 5 units. The pilot also reported that while heading back to DAL, the start lever on the No. 2 engine was CLOSED. An uneventful single engine landing was performed and no injuries were reported to any of the occupants.
Probable Cause and Findings
A total loss of engine power due to the No. 2 engine experiencing a release of its fan spinner through the fan cowl as a result of an unidentified object striking the spinner, separating it from the fan disk and causing the spinner to be ingested into the fan blades.
