THE PLT HAD JUST COMPLETED AN ENG OVERHAUL & WAS TEST FLYING THE HELICOPTER. WHILE MANEUVERING AT APRX 100 FT AGL, THE ENG LOST POWER & THE PLT INITIATED AN AUTOROTATION. DURING THE LANDING, THE HELICOPTER IMPACTED HARD ON RISING TERRAIN, ROLLED ONTO ITS SIDE & BURNED. AN INVESTIGATION REVEALED THAT THE ENG HAD SEIZED. CONTAMINATION HAD ENTERED THE OIL SYSTEM DURING THE OVERHAUL WHICH HAD RESULTED IN THE SEIZURE. THE PLT WAS NOT A CERTIFIED POWERPLANT MECHANIC.
