Event Details
During the takeoff roll, the pilot reported that the airplane encountered a significant wind gust from the right. The gust forced the airplane to exit the left side of the runway. Subsequently, the landing gear collapsed and the airplane collided with metal pylons which surrounded the wind sock. The airplane sustained substantial damage to both wings, fuselage, horizontal stabilizer, and elevator. The pilot reported no mechanical failures or anomalies prior to or during the flight that would have prevented normal flight operation.
Weather Conditions
The pilot checked the winds via his onboard weather reporting device during the run-up. He stated that the 25 knot wind sock was about ¾ full just moments before the takeoff roll. According to the Airport/Facility Directory, the Airport Remarks state that the airport is located in mountainous terrain with occasional strong winds and turbulence. A lighted windsock is available at runway ends and centerfield. With southerly crosswinds in excess of 15 knots, turbulence and possible windshear along the first 3000 feet of Runway 27 can be expected. The reported wind at the airport during the time of the accident was from 200 degrees true at 22 knots, with gusts at 33 knots. The departure runway heading was 27. The crosswind component during the time of the accident was 26 knots.
Aircraft Information
According to the pilot operating handbook, the maximum demonstrated crosswind component for this airplane is 17 knots. The crosswind component of 26 knots exceeded this limit.
Probable Cause
The probable cause as determined by the official investigation is the pilot's decision to takeoff in high crosswind conditions resulting in the inability to maintain an adequate crosswind correction, consequently failing to maintain directional control and departing the runway, and subsequently colliding with fixed airfield equipment.
