ALBUQUERQUE, NM, USA
N93DB
BUCHANAN S1-S
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.
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.
