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 CFI PULLED THE THROTTLE TO IDLE TO SIMULATE AN ENG FAILURE BUT DURING THE EMERGENCY PROCEDURES, THE STUDENT PULLED THE MIXTURE TO THE IDLE CUTOFF POSITION. THE CFI DID NOT NOTICE THIS UNTIL THE ENG DID NOT RESPOND WHEN THE STUDENT APPLIED THE THROTTLE TO GO-AROUND. AT THAT TIME THE ACFT WAS JUST ABOVE SAWGRASS & THE CFI PUSHED THE MIXTURE TO THE FULL RICH POSITION & THE ENG DID START BUT NOT BEFORE THE MAIN LANDING GEAR CONTACTED THE SAWGRASS.
NTSB Probable Cause
TOTAL LOSS OF ENGINE POWER DUE TO INADVERTENT USE OF THE MIXTURE CONTROL BY THE STUDENT, INADEQUATE SUPERVISION BY THE CFI, AND DELAYED REMEDIAL ACTION BY THE CFI RESULTING IN THE OFF AIRPORT LANDING.
