Probable cause

The pilot’s decision to take off in a crosswind that exceeded the airplane’s maximum demonstrated crosswind capability and his subsequent inability to maintain directional control.

NTSB narrative

According to the pilot, he made a precautionary landing on a road to investigate a possible airplane malfunction. During the landing, he noted that the wind was out of the north and about 25 to 35 mph. After troubleshooting, the pilot attempted to take off from the road to the east. According to the airplane manufacturer, the airplane's maximum demonstrated crosswind is 20 knots at 90 degrees. During the takeoff roll, the pilot lost directional control of the airplane, and the airplane departed the road. Subsequently the right main landing gear collapsed, and the right wing impacted the ground. The pilot reported no preimpact mechanical malfunctions or failures with the airplane or engine that would have precluded normal operation.
