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.

DURING TAKEOFF, THE AIRPLANE WAS HEARD TO REDUCE POWER AT MID-FIELD, THEN FULL POWER WAS APPLIED. IT CLIMBED TO ABOUT 6 FT, SETTLED BACK ONTO THE RWY, CLIMBED AGAIN TO 6 FT, SETTLED AGAIN, THEN CONTINUED ITS TAKEOFF ROLL USING MOST OF THE 5,850-FT RWY UNTIL REACHING THE ARPT PERIMETER FENCE. IT CLIMBED TO ABOUT 20 FT AGL, THEN SETTLED INTO A HOUSE. THE DENSITY ALTITUDE WAS 7,800 FT. ENGINE EXAMINATION REVEALED THAT THE MAGNETO-TO-ENGINE TIMING WAS OFF, THE MAGNETO INTERNAL TIMING WAS OFF ON BOTH SETS OF POINTS, AND BOTH POINT GAPS WERE OFF. IN ADDITION, 5 OF THE 12 SPARK PLUGS WERE FOUND TO HAVE WORN ELECTRODES. ONE SPARK PLUG WAS NOT APPROVED FOR THE ENGINE. A 100-HR INSPECTION HAD BEEN COMPLETED ON 2/2/93, ABOUT 17 FLIGHT-HOURS BEFORE THE ACCIDENT.

NTSB Probable Cause

A PARTIAL LOSS OF TAKEOFF POWER DUE TO INADEQUATE MAINTENANCE AND INSPECTION WHICH FAILED TO DETECT MAGNETO AND SPARK PLUG DEFICIENCIES. IN ADDITION, THE PILOT FAILED TO ABORT THE TAKEOFF AFTER TWO UNSUCCESSFUL ATTEMPTS TO GET AIRBORNE. FACTORS WHICH CONTRIBUTED TO THE ACCIDENT WERE: THE HIGH DENSITY ALTITUDE AND THE PILOT'S LACK OF PILOTING EXPERIENCE.
