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 stated that he recently installed a newly rebuilt engine in his unregistered experimental amateur-built airplane and completed a 1-hour break-in procedure the day prior to the accident. He was departing from a soft field and he believed that the engine got wet or that the propeller was damaged by mud or rocks during the takeoff, reducing thrust. The airplane gained only 40 to 50 feet of altitude before it impacted trees. The airplane incurred substantial damage to the empennage. The reason for loss of engine power was not determined. The pilot stated he should have taken the airplane back to his home base and not attempted the takeoff from the soft field.
