N5312G

The pilot reported that he was practicing touch and go landings with the tailwheeled airplane to runway 27. During his seventh landing, the "wind velocity increased and a crosswind developed." As the airplane touched down, it veered to the left and departed the grass runway. The pilot reduced engine power and attempted to regain control; however, the airplane’s left wing impacted a tree, resulting in substantial damage to the fuselage and left wing. The pilot reported there were no mechanical malfunctions or failures of the airplane. A weather observation taken approximately at the time of the accident, 15 miles from the accident site, recorded the wind as 190 degrees at 14 knots.
