Accident Overview
The pilot reported that he intended to practice takeoffs and landings while remaining in the traffic pattern. Before departure, he checked Runway 36R, a grass/turf runway, to determine if it was hard enough for landing. The adjacent paved runway, Runway 36L, was covered with ice. The pilot decided to take off from Runway 36L and land on Runway 36R. He departed and flew a left-hand traffic pattern.
