Incident Summary
A pilot reported that during preparation for a flight to another airport, the airplane experienced a loss of directional control while taxiing on the parking ramp. The intended maneuver was a 90-degree left turn to proceed directly toward the active runway. After applying power, the airplane began moving forward and initiated a left turn.
Sequence of Events
According to the pilot, after the airplane reached the desired heading, he applied right rudder pedal input to stop the turn, but the airplane continued turning left. He then applied the right wheel brakes, but the airplane did not stop. The left turn continued until the left wing and propeller impacted a snow bank located at the edge of the parking ramp. The impact resulted in substantial damage to the left wing.
Pilot Statement
The pilot later stated that for this particular flight, his seat may not have been positioned sufficiently far forward. He indicated that this likely prevented his legs from activating the rudder pedals or brake pedals to their full range of travel.
