On February 9, 2004, about 1440 eastern standard time, a Piper PA-23-250, N6760A, was substantially damaged while landing at the Great Barrington Airport (GBR), Great Barrington, Massachusetts. The certificated commercial pilot and a passenger were not injured. Visual meteorological conditions prevailed and no flight plan was filed for the flight that departed the Waterbury-Oxford Airport, Oxford, Connecticut. The personal flight was conducted under 14 CFR Part 91. The airplane was landing on runway 29, a 2,579-foot-long, asphalt runway. In a written statement, the pilot said he experienced a crosswind during the landing approach. He further stated: "...I misjudged my altitude and speed for this day and landed halfway down the runway. Unfortunately, it was too short and too fast for the conditions, and I skidded off the end of the runway into a snow bank...." Examination of the airplane by a Federal Aviation Administration inspector did not reveal any mechanical malfunctions. Nor did the pilot report any. The pilot reported 3,409 hours of total flight experience, which included 750 hours in make and model. Winds reported at an airport located about 18 miles north-northeast of GBR, at 1454, were from 230 degrees at 10 knots, with 17 knot gusts. In addition, the winds were reported as variable between 200 and 260 degrees.
