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.

According to the pilot, he was on a one mile final approach to runway 36 at 800 feet with the glider engine stowed. He noted that the wind was changing and extended the flaps. The airspeed was between 55 and 60 knots when the airbrakes were extended to start a descent. The altitude was high and the glider began to descend at a rapid rate. The pilot closed the airbrakes to arrest the descent rate but realized he was to low and unable to land on the intended runway. The glider collided with a tree, and a post-accident examination revealed that the left wing was substantially damaged. The pilot reported no pre-impact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
NTSB Probable Cause
The pilot's improper use of wing spoilers during approach resulting in an altitude loss and collision with a tree.
