Incident Overview
A pilot reported that during a wheel landing with a 90-degree crosswind of about 8 knots from the left, the airplane became 'squirrelly' as the tail wheel was being lowered and the flaps were raised. The pilot added power to perform a go-around, but the airplane departed the right side of the runway.
Sequence of Events
The airplane continued for 345 feet after leaving the runway, maintaining a 30-degree angle relative to the runway centerline, until it struck a parked airplane. Continuous tire tracks from the accident airplane were observed from the runway to the accident site.
Passenger Account
A pilot-rated passenger in the airplane reported that he told the front seat pilot to cut the power when the airplane departed the runway. Receiving no response, he manually closed the throttle before impact.
