On January 10, 2005, approximately 1650 central standard time, a Myers Kit Fox Series VI homebuilt-experimental airplane, N982KF, registered to and operated by a private individual, was substantially damaged during impact with terrain following a loss of control after takeoff from the Cleveland Municipal Airport (95F), near Cleveland, Oklahoma. The private pilot, who was the sole occupant of the airplane, was seriously injured. Visual meteorological conditions prevailed and a flight plan was not filed for the 14 Code of Federal Regulations Part 91 personal flight. The flight originated from the Westport Airpark (4F1), near Tulsa, Oklahoma, at 1615. According to witnesses near the airport, the airplane was observed performing touch and go landings on runway 18 at 95F. One witness, who was located on airport property, observed the airplane flying "very low" to the ground at a "high rate of speed" (in ground effect) parallel to the runway. The witness added that as the airplane reached the end of the runway, it "climbed steeply," started a left turn, and "spun" nose first into the ground. There was no post-impact fire. In a written statement, the 389-hour private pilot reported that he did "not have any recollection of the accident due to a head injury and/or medications." Data provided by the pilot revealed that he had accumulated a total of 27 hours in the same make and model aircraft. An FAA inspector, who examined the wreckage at the accident site, reported that the horizontal stabilator and electric trim for pitch control did not exhibit pre-impact anomalies. Additionally, a check of flight control cable continuity did not reveal any abnormalities other than impact damage. Structural damage to the left wing and cabin area was observed. At 1650, the automated weather observing system at the Richard Lloyd Jones Jr. Airport (RVS), located approximately 27 miles southeast of the accident site, reported wind from 210 degrees at 7 knots, 10 statute miles visibility, few clouds at 28,000 feet, temperature 66 degrees Fahrenheit, dew point 57 degrees Fahrenheit, and a barometric pressure setting of 29.87 inches of Mercury.
