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 Probable Cause

THE PILOT'S PREMATURE LIFTOFF AND THE RESULTANT STALL DURING TAKEOFF. A FACTOR WAS THE DENSITY ALTITUDE.

Full Narrative

On August 22, 1994, at 1400 central daylight time, an Air Tractor AT-301, N4360S, was substantially damaged during takeoff near Lazbuddie, Texas. The commercial pilot was not injured. Visual meteorological conditions prevailed for the local aerial application flight. The flight had departed the airstrip earlier that day with the same load. On this flight the temperature was up to 93 degrees Fahrenheit with a calculated density altitude of 6,500 feet. According to the pilot, the wind was gusty, almost a direct crosswind, as the aircraft lifted off, climbed approximately 6 feet above the ground and then settled back onto the runway. The pilot "shut the engine down" and the airplane rolled into a fence at the departure end of the runway and came to rest inverted in a field adjacent to the runway. The FAA Inspector reported damage to the engine, engine mount, firewall, and wings. According to the pilot's enclosed report, there were no mechanical malfunctions.
