At 11:31 central time, a Beech A36 lost engine power and was damaged in the ensuing forced landing. The pilot was not injured. The flight was a post-maintenance test flight and the airplane had just come from its annual inspection. A ground run showed no anomalies, but during a post-accident inspection it appeared a fuel line had loosened enough to leak but not enough to come off its fitting. There was evidence of an engine compartment fire.
