Circumstances:
The commercial pilot and copilot reported that, after a normal start and taxi, the airplane was cleared for takeoff. The pilot reported that he began the takeoff roll and, once the airplane reached 100 knots, he rotated the airplane. He added that the airplane immediately experienced an uncommanded right yaw and that the right rudder pedal was "at the floor." Both pilots applied pressure to the left rudder pedal; however, the pedal barely moved. The pilot then tried to manipulate the rudder trim; however, the airplane continued to yaw right. He then manipulated the throttle controls and landed the airplane on the left side of the runway. The airplane remained difficult to control, and subsequently, the left landing gear collapsed, and the airplane slid to a stop on its left side. Postaccident examination of the cockpit revealed that the rudder trim was fully trimmed to the nose right position. Examination of the rudder and rudder trim assembly revealed no anomalies that would have precluded normal operation. The reason for the unmanageable right yaw could not be determined.
Probable cause:
The airplane's unmanageable right yaw during takeoff for reasons that could not be determined because postaccident examination of the rudder and rudder assembly did not reveal any anomalies that would have precluded normal operation.
