The NTSB's narrative final · quoted from the NTSB record
The pilot made a "Mayday" call, and reported that he was at 4,000 feet msl and descending without engine power. An approach controller acknowledged the pilot's distress call, and attempted to direct him to a nearby airport. The pilot subsequently elected to perform a forced landing to a field; however, during the landing the airplane impacted a private residence. A witness, located about 4 miles north of the accident site, saw the accident airplane flying normally, then heard a "bang." He then heard about 5 seconds of intermittent engine noise, followed by white smoke, which began trailing behind the airplane as it flew. The propeller was found about 3.4 miles from where the airplane came to rest. Examination of the airframe revealed no mechanical anomalies, and examination of the engine revealed damage consistent with an engine overspeed. Examination of the propeller, propeller flange, and associated hardware revealed signatures consistent with insufficient propeller retention bolt torque.
