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 COMMERCIAL PILOT REPORTED THAT HE LOST DIRECTIONAL CONTROL DURING LANDING ROLL WITH A GUSTING CROSSWIND. THE HOMEBUILT BIPLANE DRAGGED ONE WING ON THE RUNWAY, THEN NOSED OVER. THE PLANE CAME TO REST INVERTED. THE VERTICAL AND HORIZONTAL STABILIZERS WERE BENT AND DAMAGED, AND BOTH WINGS WERE DAMAGED ON THE UPPER SURFACES. THE LOWER WINGS WERE FRAYED FROM FRICTION WITH THE RUNWAY. A SELF LOCKING NUT WAS MISSING FROM THE TAIL WHEEL LOCKING CABLE ATTACHMENT, ALLOWING THE TAIL WHEEL TO CASTER FREELY. THE BOLT (TO BE HELD IN PLACE WITH A LOCKING NUT) WAS FOUND ON THE RUNWAY.

NTSB Probable Cause

THE FAILURE OF THE PILOT IN COMMAND TO ADEQUATELY COMPENSATE FOR THE WIND CONDITIONS AND TO MAINTAIN DIRECTIONAL CONTROL DURING LANDING ROLL. A CONTRIBUTING FACTOR WAS THE FAILURE OF THE TAILWHEEL LOCKING ASSEMBLY.
