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.

According to the captain, while on approach to land, he distracted the crew by pointing out a boat dock. He said that after touchdown, he realized that the landing gear was not extended, and the airplane slid on its belly, sustaining substantial damage to the underside of the fuselage. He said that the crew did not hear the landing gear retracted warning horn, and the accident could have been prevented if he had not distracted the crew. The captain reported that there were no mechanical malfunctions with the airplane that would have precluded normal operation.
NTSB Probable Cause
The flight crew's failure to extend the landing gear, which resulted in an inadvertent wheels up landing. Contributing to the accident was the flight crew's diverted attention.
