AFTER LOWERING COLLECTIVE CONTROL TO PERFORM A SIMULATED AUTOROTATIVE LANDING WITH FULL THROTTLE APPLIED, THE CFI OBSERVED THAT THE ENG RPM DROPPED TO ZERO & THE MANIFOLD PRESSURE GAUGE INDICATED 30 INCHES. DURING THE EMERGENCY DESCENT AT AN ALTITUDE OF 100 FEET, HE OBSERVED POWER LINES AHEAD. HE PULLED COLLECTIVE CONTROL & CLEARED THE LINES BUT THE HELICOPTER LANDED HARD RT SKID LOW. THE RT SKID BROKE & THE HELICOPTER ROLLED ON ITS RIGHT SIDE & CAME TO REST. THE HELICOPTER WAS RECOVERED & TAKEN TO THE OPERATOR'S FACILITY FOR EXAM. THE FUEL SYS WAS CHECKED FOR CONTAMINANTS; NONE WERE FOUND. FUEL QUANTITY WAS SUFFICIENT TO SUSTAIN ENG OPERATION. THE ENG WAS STARTED & FOUND TO OPERATE NORMALLY. NO DETERMINATION COULD BE MADE AS TO THE REASON FOR THE REPORTED LOSS OF ENG POWER.
Probable Cause: IMPROPER COLLECTIVE AND CYCLIC CONTROL INPUT BY THE PILOT-IN-COMMAND DURING THE FORCED LANDING FOLLOWING TOTAL LOSS OF ENGINE POWER DUE TO UNDETERMINED REASONS.
