Narrative:About 14 minutes after takeoff, at approximately 08:40, the co-pilot called Bartlesville Radio and stated that the flight was having engine trouble, with an oil temperature over 100 degrees, and requested that the IFR flight plan be cancelled as they might return. At 08:45, the co-pilot again stated that they could not unfeather the propeller. Bartlesville's single 4,600-foot runway had patches of snow and ice while all runways at Tulsa Airport were clear, so the pilot decided to continue to Tulsa. Heading for Tulsa, the aircraft was seen to plunge to earth in a spin. Impact with the rolling terrain was on a heading of about 240 degrees, while the wings were about level, and while the nose-down angle was close to vertical. An explosion and intense fire ensued.
PROBABLE CAUSE: "The Board determines that the probable cause of this accident was loss of flying speed during single-engine flight for reasons undetermined. resulting in a spin to the ground."
