Accident Investigation Report: Western Air Lines, Inc, North Hollywood, California, April 24, 1946

NC-33621, owned and operated by Western Air Lines, crashed two miles northwest of Lockheed Air Terminal, Burbank, California, at 0157, April 24, 1946, during an emergency single-engine approach to that airport, following an engineering test flight. The crew of three were fatally injured and the Douglas DC-3A was demolished by impact and subsequent fire. The Civil Aeronautics Board determines that the probable cause of this accident was the action of the pilot in descending to an excessively low altitude in an attempt to remain in contact after encountering ground fog during an approach for an emergency landing. A contributing factor was failure of the left engine due to excessive oil accumulation in the No. 8 cylinder prior to starting the engine. A further contributing factor was the failure of maintenance personnel to take proper precaution for drainage of oil accumulation prior to starting the engine.
