According to a written report submitted by the operator, the pilot was landing the tail-wheel equipped airplane on runway 03. Shortly after touchdown, during the roll-out, the pilot manually unlocked the airplane's tail wheel. Upon releasing the tail-wheel lock, "...directional control of the airplane was lost." The airplane subsequently ground looped resulting in substantial damage to the right wing. The 1257 METAR observation at Great Falls reported winds from 070 degrees at 6 knots. The accident report submitted by the operator indicated that there were no mechanical malfunctions or failures with the aircraft that may have contributed to the accident.
Probable Cause: Pilot's failure to maintain directional control of the aircraft while landing.
