(-23) Instructor simulated right engine failure inside final approach fix. Instructor believes he simulated engine failure via retarding throttle on right engine. During simulated single engine landing the student bounced the aircraft. Following bounce the instructor instructed the student to go around. When throttles were advanced for both engines the right engine failed as climb was established resulting in the aircraft rolling and turning to the right. As directional control was being lost the instructor took over controls, reduced power, and righted the aircraft prior to impact. Aircraft crossed the infield and taxiway then came to rest on parking ramp. When aircraft recovery was initiated by mechanic he noted that the left fuel selector was on and the right fuel selector was off. Neither the instructor nor student remembers turning fuel selector off until after the aircraft had crashed. Aircraft received substantial damage consisting of bent right wing, collapsed nose gear, blown left main tire, right prop strike and wrinkling of both sides of the fuselage from the nose to just aft of the pilot seats. During subsequent inspection of the fuel system it was noted that there was no fuel in the right carburetor float bowl nor anywhere else in the fuel system outboard of the fuel selector valve for the right engine. When the fuel system was reconnected and the right fuel selector turned on, the right engine started and idled normally.
