Narrative:
The airplane made a wheels-up landing on runway 29 at Effingham County Memorial Airport, Effingham, Illinois. The pilot reported that he had lowered the landing gear and completed a checklist consisting of seven items, one of which was the landing gear. He stated that on the base leg he began to add flaps. He touched down on runway's centerline; at which point, he began to hear a low vibration. He added that when the throttles were retarded to the idle position, the gear warning horn sounded, which he initially thought was the stall warning horn. The pilot stated that during the aircraft's recovery, he had selected the master switch to the 'ON' position, and the landing gear warning horn sounded. He then stated that when he lowered the landing gear handle the landing gear extended. The pilot described the placement of the flap control and landing gear control as being separated by a distance of approximately five inches.

Probable Cause: inadvertent wheels-up landing and the checklist not followed by the pilot. The landing gear lever not engaged was an additional cause.
