On March 18, 2000, at 2115 central standard time, a Beech 58, N19WM, operated by Multi-Aero, Inc., collided with the terrain following an inadvertant landing gear retraction after touchdown on runway 36 (2,202' x 49') at the Festus Memorial Airport, Festus, Missouri. The pilot was not injured and the airplane was substantially damaged. The 14 CFR Part 91 flight was operating in visual meteorological conditions and an IFR flight plan was filed. The flight originated from Dexter, Missouri, at 2040 cst. The pilot reported he was performing a short field landing when the accident occurred. He reported he intended to raise the flaps during the landing roll to "...shift weight of the aircraft to the wheels to assist in stopping." The pilot reported that instead of retracting the flaps he inadvertently retracted the landing gear. The pilot's recommendation as to how the accident could have been prevented was "Do not touch anything until clear of runway."
