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 during the downhill takeoff from a remote unimproved airstrip, with a quartering headwind, the wind shifted as the airplane became airborne. The airplane settled "with about 100 yds left on the runway" and he continued "trying to milk the flaps" to become airborne while continuing downhill. The airplane never attained flying speed again and settled into a creek bed. After the impact with terrain, the pilot reported there were "several wind gusts of 15-20 mph coming downhill". The airplane sustained substantial damage to the fuselage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
