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 private pilot was returning to the airport after a personal local flight made under Title 14, CFR Part 91. He said while on final approach to land, he was advised by the tower of a flock of geese that took off from an adjacent waterway. During touchdown, he said a pilot waiting to takeoff reported sighting the geese, and his attention was diverted for a moment. In that moment he said the airplane started a turn to the right. He indicated he applied left rudder and power, but could not stop the turn. The pilot said the left main landing gear collapsed in the turn, and the left wing struck the ground. He noted there were no known mechanical problems with the airplane prior to the accident. The airplane sustained substantial damage to the landing gear box and the left wing during the accident.

NTSB Probable Cause

The pilot's failure to maintain directional control during the landing roll, which resulted in a ground-loop. A factor contributing to the accident was the pilot's diverted attention during the landing.
