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.

While on approach for landing at the initial airport, the pilot reported encountering gusty wind conditions. The airplane landed hard and bounced back into the air, and the pilot initiated a go-around. During the go-around the airplane struck brush, a runway end identifier light box, and a taxiway light. The pilot did a flyby of the tower, and tower personnel indicated that the landing gear did not appear to be down, and that he should divert to an alternate airport for the emergency landing. The pilot diverted to an alternate airport, and performed a flyby of the tower. Tower personnel reported that the landing gear appeared down. After the airplane touched down, the right main landing gear collapsed, followed by the left main and nose landing gear. The airplane skidded down the runway, coming to rest upright. The fuselage, both wings, and the horizontal stabilizer were substantially damaged. The pilot reported no mechanical problems with the airplane during the initial landing attempt.

NTSB Probable Cause

The pilot's improper landing flare in gusting wind conditions resulting in a collision with an airport sign.

Full Narrative

On June 20, 2009, about 1318 Pacific daylight time, a Mooney M20TN, N411JL, experienced a landing gear collapse after touch down at the Norman Y.
