Probable cause

The NTSB’s determination of the probable cause, and any contributing factors.

Directional control was not maintained. A factor to the accident was: a tail wind.

Analysis

At the conclusion of an air show, the airplane was cleared for release by the air show coordinator. The coordinator was told by ATC that runway 12 was the active. The pilot stated to the air show coordinator that he didn't want to take off on this runway, as the winds favored runway 30, and that his airplane could not handle a tail wind component on take off. After calls were made to air traffic personnel about the active runway, the pilot was informed that runway 12 was still active and he was cleared for take-off on runway 12. During the take-off ground run, the airplane veered sharply to the left and the left wing contacted the ground. The pilot reduced power and attempted to straighten the direction of travel; however, the right wing then contacted the ground and the airplane came to a stop. The winds were reported from 230 degrees at six knots.
