Event
A flight instructor was conducting an introductory flight with a new student. While demonstrating emergency procedures at approximately 400 feet above the ground, the helicopter experienced a loss of engine power.
Emergency Landing
After the power loss, the instructor assessed the ground below as unsuitable for landing. He turned the helicopter south and aimed for a flat area of terrain. He cushioned the landing by raising the collective, and the helicopter subsequently sank 6 inches into the ground.
Postaccident Examination
Examination of the engine itself disclosed no abnormalities. However, a postaccident functional test of the engine revealed a malfunction in the engine-driven fuel pump. During testing, when the electrically-driven boost pump was switched to the OFF position, power fluctuations were noted.
Damage
All three rotor blades were bent, and the tail boom was severed.
