The pilot stated that he locked the tailwheel on his single-engine airplane prior to departure. After takeoff, he stayed in the traffic pattern and landed. However, during the landing rollout the airplane ground-looped and the airplane's lower right wing contacted the ground, breaking the wood spar. The pilot stated that postaccident examination of the airplane indicated that either hardened grease and dirt buildup may have prevented the tailwheel locking mechanism from fully engaging or that the mechanism may have been inadvertently bumped in flight.
