On September 13, 2014, about 1340 eastern daylight time, a Cessna T210N, N5132C, nosed over following a landing overrun at the Montgomery County Airpark (GAI), Gaithersburg, Maryland. The commercial pilot and 2 other crew members were not injured. The airplane was substantially damaged. The airplane was registered to the pilot and operated by the U.S. Coast Guard Auxiliary as a public-use flight. Instrument meteorological conditions prevailed at the time which operated on an instrument flight rules clearance. The flight originated about 1130 EDT from the Millville Municipal Airport, Millville, New Jersey, and was destined for GAI. The pilot stated that the purpose of the flight was to observe boat traffic on several water ways. After doing so, he proceeded VFR to GAI, and when about 5 miles away, he observed cloud cover at the destination airport. He obtained an IFR clearance and was cleared for the RNAV (GPS) approach to runway 14, and vectored to intercept the final approach course. At TIMBE, or the final approach fix, he lowered the landing gear and 10 degrees of flaps. He continued the approach, and broke out at 500 feet but noted the flight was 50 to 100 yards left of the runway. He made a gentle right 270 degree turn while maintaining 80 knots and lined up onto final approach, where he then lowered the flaps to 40 degrees. He estimated the touchdown point was ½ way down the 4,202 foot long runway that was wet with areas of standing water, and after touchdown he applied the brakes but was unable to stop. The airplane departed the runway at the end, and travelled onto grass where it encountered a mound and the airplane nosed over. The pilot further stated that during the approach he was given the wind, but could not recall the direction. He did recall the velocity to be between 3 and 5 knots; however, after exiting the airplane he noted a 5 to 8 knot tailwind existed. A witness who was in an airplane near the approach end of runway 14 north of the runway waiting IFR release indicated a right quartering tailwind existed, and reported first observing the airplane when it was left of his position flying in a southerly direction. The witness noted the airplane banked to the right and flew over the runway turning to the north where he lost sight of it. He then noted the airplane flew over his position about 20 seconds later about 200 feet above ground level while in a southerly direction, and flew south of the runway then banked to the left correcting back. The witness estimated that from his vantage point the airplane touched down 2/3rd's to 3/4 down the runway, followed by seeing the airplane's tail in the air. The witness called on the Potomac Approach control frequency believing it was the common traffic advisory frequency to alert of the accident. According to the airport manager, the location where the airplane came to rest was approximately 725 feet past the departure end of the runway. A surface observation weather report taken at GAI at 1335, or about 5 minutes before the accident indicates that the wind was from 290 degrees at 7 knots; no gusts were reported.
