On August 19, 1996, at 1220 central daylight time, a Cessna A185F, N61609, was substantially damaged following a loss of control during takeoff near Midland, Texas. The airplane was owned and operated by Econorex Systems Inc., of Belton, Missouri. The instrument rated private pilot, sole occupant of the airplane, was seriously injured. The business flight was conducted under Title 14 CFR Part 91. Visual meteorological conditions prevailed for the planned cross country flight for which a flight plan was not filed. According to authorities at the Midland International Airport, the airplane arrived at approximately 1250 and taxied to an FBO to refuel. After refueling, the airplane was cleared for takeoff from runway 16R at 1304. Witnesses at the airport stated that the airplane made a short takeoff roll and became airborne prior to reaching taxiway "F." Witnesses added that the airplane established "a very steep climb attitude as soon as it became airborne, and subsequently nosed down" onto the west edge of runway 16R, between taxiway "F" and runway 10. Examination of the wreckage by the FAA inspector revealed that the elevator trim was in the full nose up position. The trim indicator confirmed the position of the elevator trim.
