DURING AN EXTERNAL LOAD OPERATION, THERE WAS AN INDICATION OF HIGH TORQUE AND THE OIL CHIP LIGHT ILLUMINATED. THE ENGINE LOST POWER AND THE PILOT INITIATED AN AUTOROTATION. THE HELICOPTER COLLIDED WITH THE SLOPING TERRAIN AND ROLLED OVER. INSPECTION OF THE ENGINE REVEALED THAT THE NUMBER SIX AND SEVEN OIL SCREENS WERE IMPROPERLY INSTALLED RESTRICTING THE FLOW OF OIL. THE ENTIRE ENGINE EXHIBITED SIGNS OF LACK OF LUBRICATION AND EXCESSIVE TEMPERATURES.
