On December 2, 1993, at 1651 central standard time, a Piel Emeraude CP-304, N7631C, sustained substantial damage in a crash at a private airstrip near Warrensburg, Missouri. The solo student pilot received serious injuries. The local instructional flight originated at the private strip where the accident occurred. No flight plan was filed, and visual meteorological conditions prevailed at the time. In a written statement provided to the NTSB, the pilot states that he had climbed to an altitude of 4,200 feet MSL to practice normal spin entry and recovery. Out of curiosity, he said he applied power while in the spin to see if the airplane would spin faster. The airplane's nose immediately rose, and as the airplane entered into a flat spin, the engine lost power. The pilot was unable to recover before impact with the ground.
