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 landing the airplane at an airport that was located on a lake peninsula. He reported that during the landing approach, he misjudged his altitude over the water, and the airplane struck the water short of the runway threshold. The airplane sustained substantial damage to both wings and the lower fuselage. The pilot stated that there were no preimpact mechanical malfunctions or failures with the airframe or engine that would have precluded normal operation. The pilot did not submit a Pilot/Operator Aircraft Accident Report (NTSB Form 6120.1/2), nor did he respond to a follow up request for an interview. His account of the accident was provided directly to law enforcement personnel shortly after accident.
NTSB Probable Cause
The pilot’s loss of visual reference during the landing approach which resulted in a collision with water.
