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 commercial pilot was on a passenger flight to an off-airport site when, during final approach to land, he allowed the airspeed to get too low and the airplane started to stall. He said that he initiated a stall recovery, but that the airplane landed hard and the main landing gear collapsed. The pilot said that there were no known mechanical problems with the airplane prior to the accident. The left wing spar was damaged in the accident.

NTSB Probable Cause

The pilot's failure to maintain adequate airspeed on final approach, which resulted in an aerodynamic stall and hard landing.
