Human Factors; Procedure
After two touch and go's my student and I prepared for a full stop; no flap landing. The traffic pattern was busy with other traffic; and we were switched to land on a different runway. It was the first time I flew with the student in the twin; and during the last lap in the traffic pattern I began to explain the procedures and approach speeds for the no flap landing. On the downwind leg we were cleared for a full stop landing. The before landing checklist was called; however; I do not recall verifying the gear selector was in the down position nor verifying a 'three green no red' indication. I also do not recall hearing the gear warning horn. The horn sounds very similar to the stall warning horn which I am used to hearing activating all the time. During the final approach segment in the traffic pattern I was focused on keeping the approach speed slightly higher at 90 kts. The aircraft impacted the runway and I took over controls to maintain centerline and avoid colliding with any obstacles. After the aircraft came to a complete stop; I immediately shut down and secured the aircraft and ordered an evacuation. Looking at the aircraft; the landing gear appeared to be stowed in the up position. There were no injuries to either of us on board the aircraft; and there did not appear to be substantial damage to the aircraft.
A light twin Flight Instructor experienced a gear up landing while instructing. Preparations for a no flap landing and an ATC assigned runway change may have gotten in the way of completing the landing check.
