What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
On the second sightseeing tour of the day, under the provisions of 91.147, the pilot loaded 3 passengers. He inquired as to the weight of each passenger and initially calculated that the weight was less than 600 lbs, which he estimated would keep him under max gross weight of 2400 lbs. He lifted the helicopter from the helipad and began a climb out. He left the landing area and was climbing over trees when he stated the helicopter began to lose lift. He rolled max throttle and lowered the collective, because he noticed the rotor RPM was dropping. He stated this did not correct the situation. He then entered into an auto rotation and landed on an atv trail approximately 79 yards downslope and due north of the helipad. The helicopter landed level and the tail rotor struck a slight uphill embankment. The main rotor struck some minor tree limbs. The Robinson -44 was shut down and evacuated with no injuries. No post incident fire and only minor damage was sustained. NTSB was notified.
