What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
The aircraft departed kelk, elk city Oklahoma for a part 91 personnel night VFR local flight. The pilot was properly rated and the aircraft was in annual. The flight progressed normally, cruising at 3000 MSL for the first 1 hour and 40 minutes. After departing from overhead of kclf, Clinton regional airport, Clinton ok, the aircraft traveled south until south of interstate 40. The aircraft then turned approximately 255 heading toward kcsm, Clinton Sherman Airport, Burns Flat, OK. The aircraft made an approximately 10 mile straight in approach to 17R, at 4 miles and pattern altitude, the pilot noticed a gradual engine power loss.
The pilot switched fuel tanks, turned on the fuel boost pump, pushed the throttle full in, pushed the mixture full in and pushed the prop full in. The engine was running but there was no throttle control and the engine was not producing significant power to maintain level flight. The aircraft landed is a grass field and rolled about 300 feet.
The pilot and passengers exited the aircraft and no injuries were reported.
The next day I inspected the aircraft. During landing roll, the aircraft rolled over three terraces. The aircraft came to rest next to a dirt road. The aircraft received substantial damage. Both main landing gears where broken at the pivot points and both wings had a large cress from the leading edge to the trailing edge. The aircraft either hard landed or bounced over the terraces to cause the main landing gear damage. The nose gear was not damaged and the prop did not impact the ground.
The engine cowling was removed the engine cowling to inspect the engine and engine controls. The throttle control cable was found disconnected from the engine fuel servo. A search of the engine compartment was completed and there were no throttle cable bolt, nut or washer found. No other anomalies were noted.
