Aircraft Accident/Incident Report

Hobart, Oklahoma 73651
Friday, March 19, 1999 17:20 CST

NTSB Narrative Summary Released at Completion of Accident

During the takeoff roll, at lift off speed, the engine backfired smoke and flame from the exhaust port. The pilot shut down the engine and braked to a stop; however, the airplane struck a ditch and the main landing gear collapsed. While exiting the aircraft, the pilot noticed black smoke coming from the accessory compartment. The airplane was subsequently destroyed by fire. Fire damage prevented a determination of the cause for a loss of engine power. Two days prior to this accident the pilot had experienced a loss of engine power and landed in a field. He assessed that it was possibly a carburetor float or seat sticking. On the day of the accident, the pilot replaced the carburetor and restarted the engine. There were no discrepancies found during the ground check.

NTSB Probable Cause Narrative

The loss of engine power due to an undetermined reason. A factor was the ditch.
