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 pilot reported that, before takeoff he noticed a visible layer of frost covering the airplane’s wings. He removed the frost with a towel and proceeded with the engine warm up and preflight checks which lasted about 20 minutes. During the initial climb, the airplane felt “mushy” and failed to gain altitude. The pilot elected to conduct an off-airport landing to a brush covered field. During the landing the airplane sustained substantial damage to the wings and fuselage. The pilot reported that the frost must have reformed before takeoff and that there were no pre-accident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
