On April 22, 2003, at 1430 Pacific daylight time, a Cessna 180J, N7821K, veered off the runway and collided with a ditch while landing at Angwin Airport, Angwin, California. The airplane was owned and operated by the private pilot under 14 CFR Part 91. The pilot was not injured and the airplane was substantially damaged. Visual meteorological conditions prevailed and no flight plan had been filed. The flight originated at Angwin at 1130. The pilot stated in the Pilot/Operator Aircraft Accident Report (NTSB Form 6120.1/2) that he had received an airport advisory from another airplane that the airport was experiencing winds from the west and runway 16 was recommended. He stated that during the landing roll, with the tail of the airplane still airborne, a gust of wind forced the airplane to the right despite full rudder control input and braking to the left. The airplane veered off the runway to the right and came to rest nose down in a ditch. The closest aviation weather reporting station is at Sonoma County Airport, 18 miles to the southwest. The winds recorded at Sonoma Country Airport for 1353 and 1453 were calm. The pilot reported that the winds at Angwin, at the time of the accident, were 260 degrees at 5 to 10 knots.
