Primary finding
Probable cause
The pilot's failure to maintain directional control during the takeoff roll.
Investigator assessment
Analysis narrative
According to the pilot, immediately after taking off, the prevailing wind shifted from a headwind to a tailwind and he was unable to maintain the aircraft's heading with the runway's centerline. The airplane was blown toward the runway edge and settled onto the dirt beside the runway. During the rollout, the airplane struck a taxiway location/runway holding position sign midway between the passenger compartment and the empennage, resulting in the empennage being bent approximately 70 degrees to the right. Weather reports at the time of the accident indicated that the wind was variable at 5 knots, with 10-mile visibility and clear skies. The pilot reported no mechanical anomalies with the airplane prior to the accident. An examination of the airplane revealed no mechanical anomalies.
