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 he landed on the unimproved dirt airstrip and came to a full stop. He began taxiing and started to turn around when he encountered a washed out area. The pilot stated that after proceeding about another 30 feet the left main landing gear collapsed through an eroded section of the dirt airstrip, which was not visible to him. The pilot reported that the landing gear fell about 2 feet followed by the airplane going up on its nose and the propeller striking the ground; the airplane subsequently fell back on its tailwheel. The pilot reported substantial damage to the airplane as a result of the left main landing gear strut being bent and damage to the left gear attachment structure.
