Aviation safety reports, made easier to study
NTSB Reports is an independent research and search tool for public aviation accident and incident records. It brings NTSB aviation reports, structured fields, docket files, extracted figures, photos, videos, and update history into one searchable interface.
The goal is practical safety education: make it faster to find relevant investigations, compare similar events, review factual records, and understand the evidence behind probable-cause and preliminary reports.
The investigative work and source records belong to the National Transportation Safety Board and the published investigation record. This site is not affiliated with or endorsed by the NTSB.

The pilot was performing an aerial application run when he observed smoke emanating from the engine. Immediately following the smoke, the engine experienced a partial loss of power. The pilot attempted to return to the airfield, but the airplane would not maintain altitude/airspeed. The pilot then elected to conduct a forced landing in the rice field. During the landing, the airplane rolled for 50-150 yards and nosed over, coming to rest inverted. A visual inspection of the engine failed to identify the reason for the loss of engine power. At the time of writing, the pilot had not returned a completed NTSB Form 6120.1, (The Pilot/Operator Aircraft Accident/Incident Report), as requested.

Full Narrative
The commercial rated pilot was performing an aerial application run when a “puff” of smoke came from the engine. Immediately after the puff of smoke, the engine lost power, but kept running. The pilot tried to return to the airfield, but the airplane would not maintain altitude/airspeed. The pilot then elected to conduct a forced landing in the rice field. During the landing, the airplane rolled for 50-150 yards before flipping over onto its back. The pilot was not injured; however, the airplane sustained substantial damage in the forced landing. A visual inspection of the engine failed to identify the reason for the loss of engine power. At the time this report was submitted, the pilot had not returned a completed NTSB Form 6120.1, (The Pilot/Operator Aircraft Accident/Incident Report), as requested.
