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.

ACCORDING TO THE PILOT, ABOUT TWENTY MINUTES INTO THE FLIGHT, THE LEFT ENGINE BEGAN TO RUN ROUGH. THE ENGINE ALSO DEVELOPED AN UNUSUAL SMELL AND THE CYLINDER HEAD TEMP WAS HIGH. AFTER EVALUATING THE SITUATION, THE PILOT SHUT DOWN THE LEFT ENGINE, CHANGED HIS DESTINATION AIRPORT AND ELECTED TO CONTINUE THE FLIGHT TO A MORE SUITABLE AIRPORT FOR AN EMERGENCY LANDING. AS THE FLIGHT CONTINUED, ALTITUDE BECAME MORE DIFFICULT TO MAINTAIN. THE AIRPLANE CRASHED SHORT OF THE AIRPORT AND BURST INTO FLAMES; THE PILOT ESCAPED FROM THE WRECKAGE BEFORE THE AIRPLANE WAS COMPLETELY ENGULFED. EXAMINATION OF THE WRECKAGE FAILED TO DISCLOSE A MECHANICAL PROBLEM, BECAUSE THE ENTIRE AIRFRAME WAS CONSUMED BY FIRE.

NTSB Probable Cause

A LOSS OF ENGINE POWER ON ONE ENGINE FOR UNDETERMINED REASONS.
