The flight instructor reported that the helicopter's engine lost power when they were about 15 feet above the ground while making an approach to land on a pinnacle during an instructional flight. The helicopter hit the ground hard and then rolled down the hill and came to rest on its right side. During the post accident inspection, the engine was removed from the airframe and installed into a dynamometer test stand. The engine started on the first attempt and ran smooth and exhibited no abnormal indications or sounds.
