Narrative:

Approximately 25 miles from our destination we canceled IFR and preceded VFR for landing. AWOS was reporting clear skies and winds of 310/19g27. We entered an extended right base for landing on runway 36; the only runway suitable based on the reported winds. I set the aircraft up on 5 mile final; called for 'full flaps'; which completed our before landing checklist; and adjusted the approach reference speed to 110 KTS; which included plus 5 KTS to accommodate the gust spread.the approach began using the VASI system; speeds were constant; as noted on both airspeed and angle of attack indicators. We experienced light turbulence on the approach. There were no indications of wind shear down to approximately 30 ft AGL. Below approximately 30 to 10 ft AGL; the wind intensity increased and wind direction changed rapidly from approximately 310 degrees through a range of 200 degrees. The aircraft was landed on the runway.with the main gear on the runway; throttles were brought to idle and forward pressure was applied to the yoke in an attempt to establish ground contact for nose wheel steering. As the nose of the aircraft started down a violent gust of wind from the forward left quadrant lifted the left wing and rapidly forced the aircraft right requiring me to apply left aileron. With the nose of the aircraft still off the runway and the left wing lowering to a wings level position; the aircraft lifted off the runway and was rapidly pushed to the right and off the runway. My major concern at that point was to keep the wings level and allow the aircraft to settle into the dirt. There were no injuries.

Title: A Falcon 10 pilot lost control of the aircraft while landing in gusty crosswinds and possible windshear. The aircraft bounced and settled off the downwind side of the runway with no injuries to the SOBs.
