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 INSTRUCTOR & PRIVATE RATED STUDENT WERE PRACTICING TOUCH & GO LANDINGS. ON THE THIRD APPROACH, ABEAM THE NUMBERS ON DOWNWIND LEG, THE ENGINE QUIT. THE STUDENT WAS TOLD TO FLY TOWARD THE RUNWAY WHILE THE INSTRUCTOR TRIED TO RESTART THE ENGINE, BUT WITHOUT SUCCESS. A FORCED LANDING WAS MADE IN A FIELD. THE NOSE LANDING GEAR COLLAPSED & ONE MAIN LANDING GEAR WAS TORN AWAY DURING THE LANDING ROLL. AN FAA INSPECTOR EXAMINED THE ENGINE LATER. HE REPORTED THAT THE SPARK PLUG ELECTRODES WERE WHITE IN COLOR. THE ENGINE WAS THEN OPERATED WITH A VERY LEAN MIXTURE SETTING. AFTERWARDS THE SPARK PLUG ELECTRODES HAD THE SAME WHITE COLORATION.

NTSB Probable Cause

THE FAILURE OF THE INSTRUCTOR TO PLACE THE ENGINE MIXTURE CONTROL IN THE RICH POSITION PRIOR TO BEGINNING TRAFFIC PATTERN MANEUVERS. AS A RESULT, THE ENGINE QUIT BECAUSE OF THE LEAN FUEL MIXTURE AT THE HIGH POWER SETTING REQUIRED FOR THE GO-AROUND AND DOWNWIND LEG.
