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 said that he extended the airplane’s landing gear in preparation to land but did not confirm if the gear was down and locked. As such, he was not aware that the landing gear did not extend due to a failure of the system’s hydraulic filter. The pilot landed gear up, resulting in substantial damage to the fuselage. The pilot said that when the airplane was recovered from the runway, recovery personnel were able to lift the airplane and extend the landing gear using the emergency gear hand pump.

NTSB Probable Cause

A failure of a hydraulic filter, which preluded normal extension of the landing gear. Also causal was the pilot’s failure to confirm that he landing gear was extended before landing, which resulted in a gear up landing.
