Narrative:

The mishap occurred on the third and to be the final landing to complete the check ride. Weather conditions were good VFR with visibility at least 10 miles and scattered clouds well above the altitudes we were training at. The winds were less than 6 KTS to light and variable from the southeast. The take off was normal. After lifting off; I selected the flaps up; and when no runway was available for landing I selected gear up. Continued on runway heading to 1;000 ft before turning downwind. Reduced power to 16' mp and props to 2;400 RPM. On downwind; performed the landing checklist gump. I checked the fuel selectors were on the main tanks; selected the gear down and confirmed three green lights orally (the inspector confirmed as well); mixtures were already forward and moved the prop levers to full forward. I remember reaching to select flaps 15 degrees. Turned base leg and noticed I was starting to get to low and added power to arrest the descent between 500 and 600 ft. Speed control remained constant at about 120-125 mph from the time gear was selected down thru final approach. After arresting the descent; I performed a final gump check noting that the gear lights were still three green. There were no abnormal indications at any time through out the pattern and approach. When I turned final approach; the VASI showed that I was high on the approach. I began reducing power; approach speed remained constant between 120 - 125 mph. As I approached the end of the runway; I reduced the power to idle (heard no gear horn come on) and flared for the landing. In the flare; I noticed I had flared high and let the plane settle slightly before I continued the flare. The next thing I knew we were sliding on the belly of the airplane and skidded to a stop just short of the intersection. Smoke began coming into the cockpit center forward. The inspector said fire! Fire! Fire! And exited the aircraft. I shut off the mixture and prop controls; magnetos; alternators and master switch and exited the aircraft. No fire occurred and there were no injuries. I called the control tower to tell them what had happened and call FSS to cancel our VFR flight plan. No emergency was declared by me. Recovery operations began to clear the runway and move the aircraft back into the hangar.
