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
CEN25LA403
The pilot reported that there was a total loss of engine power while 1,200 feet above ground level and about 6 nautical miles short of his destination. He performed an off-airport landing, in a pasture, with cows at the far end. During short final, the pilot had to maneuver to avoid rough terrain and a fence and then flared the airplane too high and yawed to one side which resulted in a hard landing. The tailwheel collapsed and there was substantial damage to the rudder. The pilot reported that there were no preaccident mechanical malfunctions or failures that would have precluded normal operation. He stated that a miscalculation of fuel quantity and fuel burn led to the fuel exhaustion.
NTSB Probable Cause
The pilot’s inadequate preflight fuel planning, which resulted in a total loss of engine power due to fuel exhaustion and the pilot’s improper landing flare which resulted in a hard landing.
