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 of the tailwheel-equipped airplane reported that after the airplane was loaded with 2,400 – 2,500 lbs of rice seed, he exited the loading area and initiated takeoff on a 2,200-foot long runway. During takeoff roll, about mid-field, the tail lifted up as he expected, and engine instruments showed expected performance. However, acceleration seemed diminished, and he increased power “to the stops.” Subsequently, the airplane struck an embankment at the end of the runway, which resulted in substantial damage to the fuselage and bottom left wing leading edge. At the time of the accident, the pilot was departing runway 34, and wind was from 170° at 5 knots. The pilot reported that there were no preaccident mechanical malfunctions or failures that would have precluded normal operation.
NTSB Probable Cause
The pilot’s decision to take off with a tailwind and their failure to maintain clearance from terrain.
