THE DTSB
The DTSB determines the Probable Cause of this accident to be Pilot Error, in that the accident pilot took off to the south from airport 39OK and encountered engine problems of some type during the climb. Numerous witness reports indicate a ROTOT, and a resultant struggling climb, then a pronounced left turn, losing all final energy in the turn. The aircraft impacted slightly right wing low and almost flat, on a heading of around 080 degrees, 3307 feet east of the departure runway centerline. The aircraft did not stall or spin, but ended up trying to land with insufficient airflow to flare or turn, and impacted very hard, and then impacted trees. The occupants were trapped in the fuselage and a fire erupted immediately. The impossible turn was impossible in this accident.
