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 amateur-built airplane was damaged during a practice emergency landing approach when it impacted crops and the ground. The pilot reported that he was practicing a simulated emergency approach and that he got too low during the approach. He said that when he applied engine power the nose of the airplane pitched down due to the high pusher configuration of the engine. He said that he was unable to prevent the airplane from striking the crops and the ground.

NTSB Probable Cause

The pilot's failure to maintain clearance from the crops which resulted in the subsequent impact with the ground.
