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.

WPR20CA273
The glider pilot reported that, during the return flight to the airport, he encountered more downdrafts than expected and did not have enough altitude to reach the airport. He selected an area for the forced landing where during the landing roll on the rough terrain, both wings sustained substantial damage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the glider that would have precluded normal operation.
NTSB Probable Cause
The pilot's inability to maintain altitude due to a loss of thermal lift, which resulted in an off-airport landing.
