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 stated that during cruise flight in the glider he encountered significant sinking air that prevented him from being able to make his destination glider port. He elected to make an off-field landing into a field. During the landing roll, the left wing contacted the ground and turned the glider to the left. During the turn, the glider's tail assembly separated from the fuselage. There was substantial damage to the tail structure.
NTSB Probable Cause
The pilot's encounter with an area of degraded lift during cruise flight, resulting in a forced off-airport landing.
