On November 10, 2002, at 1400 eastern standard time, a Beech C35, N707D, was substantially damaged during a takeoff attempt from Federhart-Ophelia STOLport (VA99), Reedville, Virginia. The certificated commercial pilot was uninjured. Visual meteorological conditions prevailed, and no flight plan was filed for the local personal flight conducted under 14 CFR Part 91. The pilot reported that during the takeoff roll, about 60 knots, the airplane's left wheel hit a "soft spot" on the runway, causing the airplane to rotate approximately 30 degrees to the left. The pilot applied right rudder; however, he observed no response from the airplane. He then reduced the throttle and applied the brakes. The airplane veered off the left side of the runway, and impacted a pole with its right wing. The pilot reported that the runway used, runway 19, was a 2,200-foot-long, 80-foot-wide grass strip which he maintained himself. He stated that the strip was generally "soft" on the day of the accident due to several days of rain. The pilot also reported that he inspected the runway prior to takeoff; however, he did not observe any soft spots. A Federal Aviation Administration (FAA) inspector performed an on-scene examination of the airplane. According to the inspector, substantial damage was noted to the airplane's right wing, and no mechanical anomalies were observed. The pilot's most recent FAA third class medical was issued on January 29, 2001, at which time he reported 2,800 hours of total flight experience. Weather reported at Patuxent Naval Air Station (NHK), Patuxent River, Maryland, 24 miles to the north of the accident site, at 1354, included winds from 200 degrees at 12 knots, gusting to 16 knots, 7 miles visibility, scattered clouds at 2,000 feet, and broken clouds at 8,000 feet.
