The pilot reported that at the time of rotation, the airplane encountered a microburst or strong crosswind that rolled the airplane aggressively to the right, causing the wingtip to drag on the runway. The airplane exited the runway and struck a ditch, where it cartwheeled and sustained substantial damage to the right wing and the tail section. The pilot reported that there were no preimpact mechanical malfunctions or failures with the airframe or engine that would have precluded normal operation. At the time of the accident, the pilot was taking off on runway 17. The pilot stated that at the time of takeoff, the wind was from 140° to 150° at 5 to 10 miles per hour, with a thunderstorm about 20 miles east.
