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.

SEA08CA163
After a 15-minute glider flight, the pilot entered the traffic pattern for a planned full-stop landing on a grass airstrip that ran adjacent to the active paved runway. He then extended his downwind leg in order to create a greater clearance between himself and a powered airplane that was landing on the paved runway. After rolling out on base leg, the pilot realized that he had extended his downwind leg too far to reach the grass strip under the gusting wind conditions. He therefore decided to land in a field short of the grass runway. While maneuvering to land in that field, he failed to maintain clearance from a nearby tree. After the wing of the glider hit the tree, it cart-wheeled into the field, and sustained wrinkling and crushing damage to both wings and fuselage.
NTSB Probable Cause
The pilot's failure to maintain clearance from a tree while making an off-field landing in a glider. Contributing to the accident was the pilot's inadequate compensation for the gusting winds.
Full Narrative
After a fifteen minute glider flight, the pilot entered the traffic pattern for a planned full-stop landing on a grass airstrip that ran adjacent to the active paved runway. He then extended his downwind leg in order to create a greater clearance between himself and a powered airplane that was landing on the paved runway. After rolling out on base leg, the pilot realized that he had extended his downwind leg too far to reach the grass strip under the current gusting wind conditions. He therefore decided to land in a field short of the grass runway. While maneuvering to land in that field, he failed to maintain clearance from a nearby tree. After the wing of the glider hit the tree, it cart wheeled into the field, and sustained wrinkling and crushing damage to both its wings and fuselage.
