## Analysis

THE STUDENT REPORTED THAT THE ENG LOST APRX 500 RPM WHILE HE WAS PRACTICING TURNS & STALLS AT AN ALTITUDE OF APRX 3500 FT MSL. REPORTEDLY, THE SITUATION BECAME WORSE & HE WAS UNABLE TO MAINTAIN ALTITUDE. HE APPLIED CARBURETOR HEAT, BUT IT DID NOT HELP. SUBSEQUENTLY, A PRECAUTIONARY LANDING WAS MADE. DURING THE LANDING ROLL, THE NOSEWHEEL SANK IN SOFT TERRAIN & THE ACFT NOSED OVER. AN EXAM & DISASSEMBLY OF THE ENG DID NOT DISCLOSE ANY EVIDENCE OF A MALFUNCTION OR FAILURE THAT CONTRIBUTED TO THE POWER LOSS. THE TEMP & DEW POINT WERE 40 DEG, RESPECTIVELY. ACCORDING TO ICING PROBABILITY CHARTS, SERIOUS CARBURETOR ICING COULD OCCUR AT GLIDE POWER & SERIOUS CARBURETOR ICING CONDITIONS EXITED FOR CRUISE POWER.
