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 HAD MADE SEVERAL STOP AND GO TAKEOFF AND LANDINGS AT THE PRIVATE GRASS STRIP. DURING TAKEOFF TO THE SOUTH, AT AN ALTITUDE OF APRX 100 FT, THE PILOT STATED THAT THE AIRPLANE STARTED AN UNCONTROLLABLE DESCENT, STRIKING THE GROUND IN A NEAR VERTICAL NOSE DOWN ATTITUDE. HE STATED THAT THE CONTROLS WERE NOT EFFECTIVE DURING THE DESCENT. THE FLIGHT CONTROLS WERE EXAMINED, AND CONTINUITY WAS CONFIRMED. THE PILOT REPORTED THAT A SQUALL LINE WAS APPROACHING FROM THE WEST, AND BELIEVED IT WAS FAR ENOUGH AWAY TO NOT BE A PROBLEM.

NTSB Probable Cause

THE PILOT-IN-COMMAND'S POOR WEATHER EVALUATION WHICH RESULTED IN A TAKEOFF INTO ADVERSE WEATHER CONDITIONS AND A LOSS OF AIRPLANE CONTROL.
