## Analysis

ACCORDING TO A PLT/OPERATOR STATEMENT, THE PRIVATE PLT (PIC) WAS ON AN INSTRUCTION FLT. THE OTHER OCCUPANT, WAS A PERSON WHOSE COMMERCIAL PLT CERTIFICATE HAD BEEN SUSPENDENDED. THE PIC REPORTED THAT THE HELICOPTER HAD JUST RECEIVED AN ANNUAL INSPECTION & HAD JUST BEEN REFUELED PRIOR TO TAKEOFF. AFTER BRINGING THE HELICOPTER TO A HOVER, CLEARANCE WAS OBTAINED TO CROSS THE ACTIVE RWYS TO THE SOUTH SIDE OF THE ARPT WHERE POWER WAS REDUCED FOR A PRACTICE AUTOROTATION. THE AIRCREW HAD INTENDED TO MAKE A POWER RECOVERY. HOWEVER, THEY REPORTED THAT DURING THE PRACTICE AUTORATATION THE ENG LOST POWER. SUBSEQUENTLY, THE HELICOPTER WAS EXTENSIVELY DAMAGED DURING A RUN-ON LANDING. NO PART FAILURE OR MALFUNCTION WAS FOUND THAT WOULD HAVE CAUSED A LOSS OF POWER.
