During the takeoff ground run, the pilot lost directional control, causing the airplane to depart the right side of the runway and collide with terrain. The pilot had been advised of wind gusts exceeding 30 knots but chose to attempt a crosswind takeoff instead of using an available intersecting runway.

Incident Overview

During the takeoff ground run, the pilot lost directional control of the airplane. The airplane subsequently departed the right side of the runway and collided with terrain.

Sequence of Events

Prior to taxiing for takeoff, the pilot received a briefing from the airport-based Flight Service Station (FSS). The FSS informed the pilot that wind gusts were in excess of 30 knots. Despite this advisory, the pilot elected to attempt a takeoff with a crosswind component rather than using an intersecting runway that was also available for use at the time. During the takeoff ground roll, directional control was lost, leading to the runway excursion and collision with terrain.

Contributing Information

The pilot was aware of the strong gusty winds through the FSS advisory. An intersecting runway was available that could have provided a more favorable wind direction, but the pilot chose to proceed with the crosswind takeoff. No further details regarding the aircraft, occupants, or injuries are specified in the source.
