NTSB narrative
While in cruise flight, the pilot detected a change in engine sound, followed by a muffled explosion and a total loss of engine power. He declared an emergency and received vectors to the nearest airport. When he realized he was not going to be able to glide to the airport, he deployed the ballistic parachute. The parachute opened properly and the airplane landed in a field. According to downloaded data from the Primary and Multi-Function Displays, about 1 minute after departure the current from alternator 1 began fluctuating, and 10 minutes later the current began to fluctuate again but at a slower rate. Approximately 45 minutes after departure, there was a sharp reduction in exhaust gas temperature and rpms, fuel flow decreased, and the airplane began descending at a rate between 1000 and 2000 feet per minute and at an airspeed between 100 and 130 knots. About 7 minutes later, the airplane experienced a sharp negative longitudinal acceleration at 800 feet pressure altitude. The engine was functionally tested after the accident and operated at various power settings, including full power, and no anomalies were noted.
Probable cause
A loss of engine power for undetermined reasons.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status, coordinates. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
