On June 20, 2002, about 1625 eastern daylight time, a Mooney M20, N3282F, was substantially damaged while landing at the Hagerstown Regional-Richard A. Henson Field Airport (HGR), Hagerstown, Maryland. The certificated private pilot and passenger were seriously injured. Visual meteorological conditions prevailed. No flight plan had been filed for the flight, which originated at Jackson County-Reynolds Field Airport (JXN), Jackson, Michigan. The personal flight was conducted under 14 CFR Part 91. In a written statement, the pilot said he was performing his second approach to runway 27, a 5,460-foot long, 150-foot wide, dry, asphalt runway. During the first approach, the airplane came in high and the pilot elected to perform a go-around. During the second approach, the pilot said he encountered a gust of wind, which "threw the airplane off the glide path" and the airplane landed "long," with about 1,500 feet of runway remaining. The pilot added that when he initially applied the brakes, they responded to gentle pressure; however, they "faded quickly." The airplane departed the end of the runway, struck an airport boundary fence and came to rest about 800 feet beyond the departure end of the runway. Witnesses reported they observed the airplane touch down about 4,000 feet beyond the approach end of the runway. The airplane bounced three times, and smoke was observed emanating from the airplane's tires before the airplane "launched" off the departure end of the runway. Examination of the airplane, which included the brake system by a Federal Aviation Administration inspector, did not reveal any pre-impact malfunctions. Winds reported at the airport about the time of the accident, were from 170 degrees at 8 knots.
