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 PILOT ALLOWED THE RIGHT OUTBOARD ENGINE POD TO DRAG ON THE RUNWAY WHILE LANDING. THE INTERNATIONAL FLIGHT EXECUTED A ILS APPROACH TO RUNWAY 14 AND WHEN THEY WERE HANDED OVER TO THE TOWER, THEY REQUESTED A VISUAL APPROACH TO RUNWAY 8. THE TOWER CLEARED THE FLIGHT FOR THE SIDE STEP MANEUVER. THE CAPTAIN DELAYED INITIATING THE SIDE STEP MANEUVER UNTIL HE WAS 350 FEET AGL, AND BANKED THE AIRPLANE TO THE LEFT, ATTAINING A BANK OF 32.6 DEGREES, FOLLOWED BY 20.8 DEGREES BANK TO THE RIGHT AT 18 FEET AGL. FINAL APPROACH ALIGNMENT WAS NOT OBTAINED CAUSING THE ENGINE TO DRAG ON THE RUNWAY. A FIRE ERUPTED IN THE BOTTOM AFT SECTION OF THE ENGINE COWLING AS A RESULT OF A BROKEN FUEL FILTER DRAIN LINE. THE FIRE WAS EXTINGUISHED WITH ONBOARD FIRE SUPPRESSANTS.

NTSB Probable Cause

THE PILOT'S FAILURE TO ATTAIN PROPER RUNWAY ALIGNMENT PRIOR TO TOUCHDOWN AND HIS FAILURE TO INITIATE A GO AROUND TO REMEDY THE SITUATION. A FACTOR WAS THE LOW ALTITUDE AT WHICH HE INITIATED THE SIDE STEP MANEUVER FOR WHICH HE WAS CLEARED.
