THE PILOT FAILED TO ADEQUATELY COMPENSATE FOR THE PREVAILING WIND CONDITIONS AND HIS FAILURE TO MAINTAIN DIRECTIONAL CONTROL. A CONTRIBUTING FACTOR WAS THE STRONG CROSSWIND COMPONENT.

Read the full NTSB narrative

THE PILOT REPORTED DIRECTIONAL CONTROL PROBLEMS WHILE LANDING IN A CROSSWIND OF 70-80 DEGREES AT 15 KNOTS OR GREATER. THE AIRPLANE TOUCHED DOWN IN THE CENTER OF THE RUNWAY, BUT QUICKLY VEERED TO THE LEFT AND WENT OFF THE RUNWAY. AN AIR TRAFFIC CONTROLLER WHO WITNESSED THE ACCIDENT SAID THAT IT APPEARED THAT A GUST OF WIND CAUSED THE RIGHT WING TO RISE SHORTLY AFTER LANDING, AND THAT THE AIRPLANE THEN VEERED TO THE LEFT. AN EXAMINATION OF THE LEFT MAIN LANDING GEAR, TIRE, AND BRAKE ASSEMBLY DISCLOSED NO ANOMALIES WITH ANY OF THE SYSTEMS OR STRUCTURE.
