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.

A CFI AND HIS RATED STUDENT WERE DEPARTING THEIR HOME BASE ON A LOCAL INSTRUMENT TRAINING AND AIRCRAFT FAMILIARIZATION FLIGHT. AFTER LEVELING AT 1500 FEET, THE ENGINE SUDDENLY, AND WITHOUT WARNING, LOST POWER. THE CFI TOOK OVER THE CONTROLS AND PERFORMED THE EMERGENCY PROCEDURES FOR AN ENGINE RESTART, WHILE SEARCHING FOR A SUITABLE FIELD FOR A FORCED LANDING. THE AIRPLANE FLEW UNDER POWER LINES, TOUCHED DOWN ON A BUSY HIGHWAY, WENT THROUGH A BARBED WIRE FENCE, COLLIDED WITH A DITCH, AND CAME TO REST IN AN OPEN PASTURE. ON SITE INVESTIGATION AND A LIMITED TEARDOWN INSPECTION OF THE ENGINE CONFIRMED THAT THE LOSS OF POWER WAS NOT DUE TO INTERNAL FAILURE OF THE ENGINE. THE NATURE OR CAUSE OF THE POWER LOSS COULD NOT BE DETERMINED OR DUPLICATED.
NTSB Probable Cause
THE TOTAL LOSS OF ENGINE POWER FOR UNDETERMINED REASONS. A FACTOR IN THE ACCIDENT WAS THE UNSUITABLE TERRAIN AT THE PILOT'S DISPOSAL.
