N116SV WAS DESCENDING FROM 2500 FEET TO 1600 FEET PER INSTRUCTIONS FROM DAYTONA APPROACH (DAB) AND WHEN TRYING TO LEVEL OFF AT 1600 FEET IT WAS OBSERVED THAT THE ENGINE HAD LOST POWER (RUNNING AT 800 RPM).

AFTER LANDING AND DURING THE ROLL OUT THE NOSE LANDING GEAR STRUCK AN OBJECT AND THE AIRCRAFT NOSED OVER. THIS WAS A PART 61 TRAINING FLIGHT AND THE INSTRUCTOR WAS PILOTING THE AIRCRAFT DURING THE EMERGENCY LANDING.
