Executive Summary:At 1308 PST, December 25, 1965, Japan Air Lines Flight 813, a Douglas DC-8-33, JA-8006, departed the San Francisco, California International Airport for Tokyo, Japan. About 1311 at 4,500 feet in a scattered cloud condition there was an explosion in the No. 1 engine and fire broke out in the engine area. The fire was subsequently extinguished and the aircraft was landed safely at the Oakland, California International Airport. There were no injuries to the crew of 10 and 31 passengers; the aircraft was substantially damaged by the engine explosion and fire that followed.

The Board determines that the probable cause of this accident was a disintegrating engine failure and inflight fire caused by the failure of maintenance personnel to properly secure the low pressure compressor section torque ring during engine overhaul.
