The NTSB's narrative final · quoted from the NTSB record

The pilot reported that during an aerial application flight with an adequate supply of fuel onboard, the engine lost power. The pilot maneuvered the airplane for an off-airport landing and, during the descent, the airplane collided with trees then the ground. Postaccident examination of the engine revealed uncontaminated fuel and no discrepancies that would have precluded normal engine operation. The engine was removed from the airframe and sent to the manufacturer’s facility for an attempted engine run. Impact-damaged components were replaced, and the engine was placed in a test cell with a test club propeller installed. The engine was started; however, impact damage to the crankshaft precluded a full operational run of the engine. The engine had accrued 1.6 hours of operation since being rebuilt by the manufacturer. The reason for the loss of engine power could not be determined.

About this page

Everything above comes from the NTSB's public accident database: the narrative, probable cause and findings are the NTSB's own words, and the coded tables behind its report (pilot, aircraft, flight, weather, injuries, sequence of events) are written out in plain English. Pilots' ages, home towns and medical details are left out on purpose. The documents and photographs are the NTSB's docket, the folder of records gathered during the investigation, shown as the NTSB released them (the NTSB redacts some personal details first) and listed under the NTSB's own titles. This site's own text never names pilots, passengers or anyone else involved. A preliminary report describes what is known soon after the event and can change; the final report, with the probable cause, usually follows one to two years later and this page is refreshed when it does. Case number ERA12LA365.
