The pilot of the tailwheel-equipped airplane reported that, during landing on grass surface next to a hard-surfaced runway, the airplane approached "too high and landed too fast." He added that he was "not sure" if he could stop the airplane in the remaining distance, so he "decided to go-around, but did not leave myself [himself] enough room to clear the trees" at the end of the landing area. Subsequently, the airplane impacted the trees and stopped. The right wing, fuselage, and windscreen sustained substantial damage. The pilot did not report that there were any preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. An automated weather observation station at the airport, about the time of the accident, reported wind from 320° at 5 knots. The pilot reported that the wind was variable, and he landed parallel to runway 29.
