During takeoff roll, a wind gust from the right forced an airplane off the left side of the runway, causing landing gear collapse and collision with wind sock pylons. The airplane sustained substantial damage to wings, fuselage, and tail.

Accident Narrative

During the takeoff roll, the airplane encountered a significant wind gust from the right, which forced it to exit the left side of the runway. The landing gear subsequently collapsed, and the airplane collided with metal pylons surrounding the wind sock.

Pilot Report

The pilot reported that he 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. He also reported that there were no mechanical failures or anomalies prior to or during the flight that would have prevented normal flight operation.

Airport Conditions

According to the Airport/Facility Directory, the airport is located in mountainous terrain with occasional strong winds and turbulence. A lighted wind sock is available at runway ends and centerfield. The remarks indicate that with southerly crosswinds in excess of 15 knots, turbulence and possible wind shear may be experienced along the first 3000 feet of Runway 27.

Wind Data

The reported wind at the airport during the time of the accident was from 200 degrees true at 22 knots, with gusts to 33 knots. The departure runway heading was 27.

Crosswind Component

According to the pilot operating handbook, the maximum demonstrated crosswind component for this airplane is 17 knots. The crosswind component during the time of the accident was 26 knots.

Damage

The airplane sustained substantial damage to both wings, the fuselage, the horizontal stabilizer, and the elevator.
