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.

ERA09CA320
The pilot described entering the traffic pattern to land on the grass adjacent to runway 26. The pilot reported that wind was out of the northwest at about 15 knots gusting to about 20 knots. The pilot said that “There was moderate turbulence on downwind which increased on base and final. The glider stalled about 8 feet above touchdown due to insufficient speed for the conditions and landed hard, breaking the tail boom… My speed on base and final was insufficient for the conditions.” The pilot reported no mechanical deficiencies or mechanical problems with the glider.
NTSB Probable Cause
The pilot's failure to maintain control of the airplane while landing in gusty winds, which resulted in a loss of adequate airspeed and a subsequent aerodynamic stall.
