The purpose of the low-level flight was to perform the aerial hunting of wild pigs and coyotes in a remote area that the pilot had not flown in before. The doors were removed from the helicopter, and the two paying passengers onboard were equipped with firearms. During the flight at 75 ft agl and 50 kts, the pilot observed two coyotes and decided to maneuver the helicopter into the wind so the passengers could engage the coyotes with their firearms. The pilot turned the helicopter to the left, into the wind, and during the turn he heard the engine rpm decrease. After checking the cockpit gauges, he noticed that the engine rpm and the main rotor rpm were both decreasing. The pilot increased the throttle, lowered the collective; however, the engine rpm and the main rotor rpm were still decreasing. The pilot maneuvered the helicopter for a forced landing. The helicopter impacted terrain and came to rest on its left side in a remote canyon. The helicopter sustained substantial damage to the main rotor system, the fuselage, the tail cone, and the tail rotor system. The pilot reported there were no preimpact mechanical malfunctions or failures with the airframe or the engine that would have precluded normal operation. The calculated density altitude for the closest metrological reporting station, near the time of the accident, was about 5,145 ft. The Robinson Helicopter Company has published Safety Notice SN-34 Aerial Survey and Photo Flights which provides pilot guidance that can also be applicable to aerial hunting flights and states that to “only fly the aircraft at speeds, altitudes, and wind angles that are safe and allow good escape routes.”
