From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

(-23) On September 21, 2008 at 1901 hours local a 1973 sorrel amateur built Skybolt, serial number 22001 crashed unoccupied in an open field in Williamstown, Kentucky. The pleasure flight of one pilot and one passenger originated from the gene snyder airport (K62). Due to the nature of his injuries the pilot has not responded to request for interview. According to the passenger the flight lasted approximately 15-20 minutes before the engine stopped operating. The passenger stated there was a puff of black smoke a violent shake, and the engine stopped. After a failed attempt to restart the engine the pilot and passenger made the decision to jump from the aircraft and utilize parachutes rather than attempting a forced landing in the field below. Both the pilot and passenger sustained serious injuries when they impacted the ground. The aircraft crashed in a nose down attitude. There was no post crash fire. A tear down investigaton of the engine revealed failure of the nr 2 connectiong rod. The rod cap separated allowing a disconnect between the crank shaft and connecting rod, seizing the engine. At the direction of the NTSB the FAA retains custody of the subject engine for further investigation.
