The pilot was landing on the 3,500-foot long runway, which was oriented 300 degrees magnetic. Prior to touchdown, the pilot decided to make "a touch and go landing." The pilot stated that after touchdown, he moved the carburetor heat to the "cold" position and applied power to take off. The engine "stumbled and popped," and the pilot aborted the takeoff and "applied hard braking." The airplane departed the end of the runway and impacted snow and ice past the runway edge. The airplane sustained substantial damage to the engine firewall. A witness stated that he saw the airplane "level off" at "the first one-third point" and continue down the runway "at an altitude of 15 feet and estimated 70 knots." He stated that the airplane touched down "on the last quarter of the runway," and he heard tires "squealing." A Federal Aviation Administration inspector, who examined the airplane after the accident, identified no mechanical malfunctions or failures. The recorded weather observation around the time of the accident included winds from 230 degrees at 11 knots, with gusts to 19 knots.
