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.

DURING A PRE-CHECKRIDE REVIEW FLIGHT, THE STUDENT PILOT WAS INSTRUCTED TO DEMONSTRATE A SHORT FIELD TAKEOFF ON A 1,640' X 100' SOD AIRSTRIP. THE STUDENT PILOT STARTED TO ROTATE WHEN THE AIRCRAFT REACHED 55 MPH AND AN ESTIMATED 3/4 WAY DOWN THE RUNWAY, AND WAS ADVISED BY THE CFI TO WAIT UNTIL 60 MPH WAS ATTAINED BEFORE ROTATION. THE STUDENT PILOT RESPONDED BY ABORTING THE TAKEOFF, REDUCING POWER AND APPLYING BRAKES. THE CFI TOOK OVER THE CONTROLS AND APPLIED 'HARD' BRAKES, HOWEVER NEITHER PILOT WAS ABLE TO STOP THE AIRCRAFT BEFORE IT RAN OFF THE DEPARTURE END OF THE RUNWAY. THE AIRCRAFT STRUCK A DITCH AND NOSED OVER.

NTSB Probable Cause

STUDENT PILOT'S IMPROPER AIRCRAFT CONTROL DURING THE TAKEOFF ROLL, AND THE SUBSEQUENT ABORTED TAKEOFF WAS PERFORMED WITH INSUFFICIENT RUNWAY REMAINING TO SUCCESSFULLY STOP THE AIRCRAFT BEFORE THE DEPARTURE END OF THE RUNWAY.
