AT AN ALTITUDE OF APRX 75 FEET DURING AN AGRICULTURAL TURN, THE PLT REPORTED THAT THE ENGINE LOST POWER. WHILE EXECUTING A FORCED LANDING, THE ROTOR BLADES CONTACTED TREES, AFTER WHICH, DURING THE DESCENT, THE RIGHT SKID COLLIDED WITH A STUMP & THE HELICOPTER ROLLED OVER. AN ENGINE TEST RUN WAS PERFORMED AND NO EVIDENCE WAS FOUND WHICH WOULD PRECLUDE NORMAL ENGINE OPERATION. THE NTSB WAS NOTIFIED OF THE ACCIDENT 20 DAYS AFTERWARD, AND, AS A RESULT, NO DETERMINATION COULD BE MADE AS TO THE QUANTITY OR TYPE OF FUEL IN THE ACFT AT THE TIME OF THE OCCURRENCE.
