The 725-hour pilot attempted to return to the airport but the airplane collided with the roof of a house located approximately 400 yards from the end of Runway 30. The collision resulted in a fire that consumed the aircraft and the house; however, there were no reported injuries to anyone on the ground. Examination of the engine by an FAA inspector, who responded to the accident site, revealed no anomalies in the engine; however, the engine sustained extensive fire damage. The magnetos and carburetor were completely destroyed by fire. The reason for the reported loss of power could not be determined. ## Factual narrative On October 5, 2003, at 1855 central daylight time, a Stinson 108-1 single-engine airplane, N845, registered to and operated by a private individual was destroyed during a forced landing following a partial loss of engine power during takeoff from the Pauls Valley Municipal Airport (PVJ), near Pauls Valley, Oklahoma. The private pilot and passenger were not injured. Visual meteorological conditions prevailed, and a flight plan was not filed for the 14 Code of Federal Regulations Part 91 personal flight. The local flight was originating at the time of the accident. The 725-hour pilot reported in the Pilot/Operator Aircraft Accident Report (NTSB Form 6120.1/2) that after completing a touch and go landing, the pilot taxied to the run-up pad, completed a run-up and operations check, then departed for a touch and go landing on Runway 35. At approximately 300 feet AGL, the pilot noticed the aircraft was climbing slower than normal and the engine rpm dropped to 2,200 rpm. The pilot stated, "I tried carburetor heat, mixture, and moved the throttle in and out with no better performance." The pilot attempted to return to the airport but collided with the roof of a house located approximately 400 yards from the end of Runway 30. The collision resulted in a fire that consumed the aircraft and the house; however, there were no reported injuries to anyone on the ground.
