On September 23, 1998, about 0930 Alaska daylight time, a wheel equipped Cessna 180 airplane, N2204C, received substantial damage while landing at an off airport site about 15 miles east of Port Heiden, Alaska. The airline transport pilot and the three passengers aboard were not injured. The local, 14 CFR Part 91 flight operated in visual meteorological conditions, and company flight following procedures were in effect. The operator was Painter Creek Lodge, and the purpose of the flight was to transport lodge clients to a hunting area. During a telephone conversation with an NTSB investigator on September 24, the pilot related that during the landing roll, he inadvertently depressed the right brake instead of the right rudder pedal. The airplane subsequently ground looped to the right, damaging the left wing and elevator. The pilot said there were no preaccident mechanical anomalies with the airplane.
