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.

IT WAS A COLD DAY, AND AS THE AIRPLANE HAD BEEN FLOWN ABOUT 45 MINUTES TO AN HOUR EARLIER, THE INSTRUCTOR DID NOT PRE-HEAT THE ENGINE. HIS THREE ATTEMPTS TO START THE ENGINE WERE UNSUCCESSFUL, SO HE DECIDED TO PRE-HEAT. HE PRIMED THE ENGINE, BUT THIS ATTEMPT WAS ALSO UNSUCCESSFUL, SO TWO ADDITIONAL SHOTS OF PRIME WERE APPLIED. BY THIS TIME, THE BATTERY WAS INEFFECTIVE, SO THE INSTRUCTOR DECIDED THAT AN EXTERNAL START WAS REQUIRED. WHILE EXITING THE AIRPLANE, THE INSTRUCTOR NOTICED SMOKE COMING FROM THE COWLING. HE ADVISED THE STUDENT TO VACATE THE AREA, AND HE SHUT OFF THE FUEL SELECTOR BEFORE LEAVING THE AREA TO GET A FIRE EXTINGUISHER. BY THE TIME HE HAD RETURNED WITH AN EXTINGUISHER, THE FIRE HAD SPREAD THROUGHOUT THE ENGINE.
NTSB Probable Cause
A FIRE IN THE ENGINE COMPARTMENT DUE TO OVER-PRIMING.
