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

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

(-23) Pilot stated engine began running rough and eventually quit. A/c diverted to nearest airport which was Georgetown, CA. A/c attempted emergency landing resulting in substantial damage to a/c. pilot and passengers sustained minor injuries. FAA did not visit accident site because NTSB gave permission to owner to move a/c from accident site. However, during engine teardown a fracture was discovered on the crank shaft which was determined the primary cause of the engine failure. (.4) on February 4, 2001, at 1605 hours pacific standard time, an amateur built fish RV6, N1198N, was substantially damaged during an off-airport emergency landing following loss of engine power near Georgetown, California. The private pilot and the sole passenger were not injured. The personal flight departed from silver springs, Nevada, at 1500, and was destined for castle airport at atwater, California. The flight was operated by the owner under 14 CFR part 91, and no flight plan was filed. Visual meteorological conditions prevailed. The pilot reported that the engine lost power while in cruise flight, and, although there was oil pressure, eventually seized before the landing. During the landing in a forest clear cut area, the landing gear impacted a tree trunk and the aircraft nosed over. Post accident disassembly of the engine revealed that the crankshaft separated at the crankshaft cheek between the number 3 and 4 throws. The owner reported he assembled the (experimental) engine himself using Lycoming parts, and that the engine had accumulated 631 flight hours since assembly. The owner was not a certificated powerplant mechanic.
