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.

NTSB Number
WPR11CA486
While participating in a soaring contest, the glider pilot entered an area where atmospheric lift was not sufficient. Instead of reversing his course toward better outlanding fields, he continued with the contest course and task. He ultimately ended up in a location where he was forced to attempt an off-airport landing on unsuitable terrain. Immediately upon touchdown, the glider encountered several small boulders that were hidden in the grass, and the left wing tip became snagged in some tall grass, resulting in a loss of directional control. During the resulting ground loop, both wings sustained substantial damage and the empennage tail boom separated from the main part of the fuselage.
NTSB Probable Cause
The glider pilot did not take timely action to locate a safe outlanding area after entering an area where atmospheric lift was not sufficient to maintain soaring flight.
Full Narrative
While participating in a soaring contest, the glider pilot entered an area where atmospheric lift was not sufficient. Instead of jettisoning the glider's water ballast to reduce its sink rate and reversing his course toward better outlanding fields, he continued on with the contest course and task. He therefore ultimately ended up in a location where he was forced to attempt an off-airport landing on unsuitable terrain. Immediately upon touchdown, the glider encountered several small boulders that were hidden in the grass, and the left wing tip became snagged in some tall grass, resulting in a loss of directional control. During the resulting ground loop, both wings sustained substantial damage and the empennage tail boom separated from the main part of the fuselage.
