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, while climbing at 500 ft per minute, over mountainous terrain, he made a right turn into the wrong canyon from the flight the day before. Realizing his mistake, and unable to make a course reversal, the terrain was rising faster than the airplane could climb. He attempted a left-hand turn to try for lower terrain, however the airplane stalled and entered a spin. The pilot regained control and put the airplane in level flight just before colliding with trees. Both wings were substantially damaged. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane or engine that would have precluded normal operation.
NTSB Probable Cause
The pilot's failure to maintain terrain clearance after flying into the wrong canyon in mountainous terrain which resulted in a collision with trees and terrain.
