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.

N116SV was descending from 2500 feet to 1600 feet per instructions from daytona approach (dab) and when trying to level off at 1600 feet it was observed that the engine had lost power (running at 800 RPM). Full engine power was applied with no change in RPM. Emergency procedures were preformed but did not restore engine power. Based on the information to the nearest airport versus altitude the pilot decided to land in a nearby field. After landing and during the roll out the nose landing gear struck an object and the aircraft nosed over. This was a part 61 training flight and the instructor was piloting the aircraft during the emergency landing.
