On September 25, 2005, about 1500 eastern daylight time, a Cessna 182Q, N5203N, was substantially damaged while landing at a private airstrip near Southampton, New York. The certificated private pilot and passenger were not injured. Visual meteorological conditions prevailed for the flight that departed Laurence G Hanscom Airport (BED), Bedford, Massachusetts. No flight plan was filed for the personal flight conducted under 14 CFR Part 91. The airplane was landing on runway 27; a 2,000-foot-long, 80-foot-wide, turf runway. The pilot reported that the airplane touched down approximately 500 feet beyond the approach end of the runway, left of runway centerline. Shortly after touchdown, the airplane began to veer left, and the pilot attempted to correct with full right pedal deflection and full right braking; however, the airplane continued left. The airplane subsequently traveled into a cornfield, rolled right, and impacted the ground. The reported wind at an airport approximately 10 miles west of the accident site, at 1453, was from 200 degrees at 12 knots. Examination of the airplane by a Federal Aviation Administration (FAA) did not reveal any pre-impact mechanical malfunctions.
