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
NYC08CA031
After being towed to an altitude of 1,800 feet, the pilot of the LET L-33 Solo glider released the towline and began "thermaling" to the northwest of the airport. After flying for approximately 11 nautical miles uneventfully, the pilot turned back to the airport. Then while thermaling on the return leg, the glider lost altitude due to the "lift conditions," and the pilot performed an off-field landing. After touching down in a hay field, the glider struck a grass covered culvert and was substantially damaged.
NTSB Probable Cause
The flight's encounter with an area of no thermal lift. Contributing factors to the accident were the pilot's inadvertent selection of unsuitable terrain with a hidden obstruction.
