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
CHI07CA087
The airplane was substantially damaged when it struck a snowbank during final approach to landing. The certified flight instructor stated that the accident landing approach was normal until the airplane was on about 1/2 mile final where the student pilot extended the flaps to 40 degrees. The instructor stated that he then "fell asleep for 20 to 25 seconds." He stated that he opened his eyes just prior to the wheels hitting the snowbank. He stated that he did not have enough time to react to prevent the impact. The airplane's nose landing gear collapsed and the airplane slid to a stop. The flight instructor stated that his inability to remain awake was due to a lack of sleep the night before.
NTSB Probable Cause
The dual student's failure to maintain the proper glidepath and clearance from terrain and the flight instructor's delayed remedial action. A factor was the flight instructor's fatigue.
