Aircraft Accident/Incident Report

Albuquerque, New Mexico 87109
Sunday, June 17, 1990 14:30 MDT

NTSB Narrative Summary Released at Completion of Accident

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 Narrative

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.
