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 solo student glider pilot reported that, during the return flight to the airport, he was unable to maintain enough lift and did not have enough altitude to cross a section of forest between his location and the airport. After he selected a field for landing, during the base leg turn, he determined that he did not have enough altitude to clear a line of trees at the threshold of the field. He then continued straight ahead, parallel to the line of trees, and impacted the ground in a small clearing. The glider sustained substantial damage to the left wing and empennage. 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 student glider’s inability to maintain altitude due to a loss of thermal lift, which resulted in an off-airport landing.
