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.

GAA19CA479
The pilot reported that, while returning to the airport, the glider descended faster than expected, so he diverted to a field for landing. The glider encountered a wind gust, and the left wing hit the ground. The glider then ground looped to the left. The glider sustained substantial damage to the fuselage, empennage, and right aileron. The pilot reported that there were no preaccident mechanical failures or malfunctions with the glider that would have precluded normal operation. The pilot reported that the wind was from 140°, between about 10 and 20 knots, and gusting. The pilot landed the glider to the south.
NTSB Probable Cause
The pilot's failure to maintain lateral control of the glider during landing in gusting wind conditions, which resulted in the left wing striking the ground and a subsequent ground loop.
Full Narrative
The pilot of the glider reported that, while returning to the airport, the glider descended faster than expected, so he diverted to an alfalfa field for landing. The glider encountered a gust of wind and the left wing "suddenly" hit the ground. The glider then ground looped to the left. The glider sustained substantial damage to the fuselage, empennage and right aileron. The pilot reported that there were no preaccident mechanical failures or malfunctions with the glider that would have precluded normal operation. The pilot reported that the wind was from 140° at 10 to 20 knots and gusting. The pilot landed the glider to the south.
