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 student pilot was returning from the practice area on a supervised solo. He was on the downwind leg for landing at 1,500 feet when he saw a crow rising from below on the airplane's left side. He heard a large thud and felt the airplane buffet. The student pilot looked to verify that no other airplanes were in the vicinity. He checked the elevator and rudder visually and by "crabbing" the airplane using the rudder and adding power; he determined that the airplane was controllable and could be landed safely. Three outboard ribs of the left wing and the spar sustained substantial damage; the top and bottom skins were wrinkled from the leading edge to the spar.
