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 was returning to the airport after releasing some skydivers. He was following a training airplane in the traffic pattern and was gaining on it, so he decided to extend his downwind leg. On final approach to runway 08, his airplane was still gaining on the other airplane. The pilot reduced power and raised the nose to reduce airspeed to 85 mph. The airplane was "low and slow" as he passed over a lake, so he added power but not soon enough. The airplane touched down on the sandy shore of the lake short of the runway. The nose gear was torn off and the airplane nosed over.

NTSB Probable Cause

The pilot's misjudgment of altitude. Contributing factors in this accident were the pilot's intentional low airspeed, his failure to execute a go-around, and the soft terrain.

Full Narrative

According to the pilot, he was returning to 1V5 after releasing some skydivers. He was following a training airplane in the traffic pattern and was gaining on it, so he decided to extend his downwind leg. On final approach to runway 08, his airplane was still gaining on the other airplane. The pilot reduced power and raised the nose to reduce airspeed to 85 mph. The airplane was "low and slow" as he passed over a lake, so he added power but not soon enough. The airplane touched down on the sandy shore of the lake short of the runway. The nose gear was torn off and the airplane nosed over. Both wings and wing struts were bent, the aft portion of the fuselage was buckled, and the vertical stabilizer were crushed.
