The aircraft departed LZ Uplift, located at coordinates BR 9274, at approximately 1430 hours. The crew states that the fuel load at that time was a little over 1000 pounds. In addition, the cargo compartment contained water cans weighing between 900 and 1000 pounds and a Chaplain who weighed 170 pounds. A hover check was performed at ten feet prior to take off during which 40 pounds of torque were pulled. After reaching the general location of the LZ, the aircraft commander requested smoke and orbited the LZ, setting up an approach to the northwest which was into the wind. The aircraft commander was forced to make a go around because of 75 foot to 100 foot trees on the approach end of the LZ. LT Feldman then set up an approach to the southwest giving him a crosswind. This approach brought the aircraft into the LZ toward the downhill side of the mountain, and eliminated the high tree barrier. The approach was planned to be terminated to a hover over a log platform which was built near the center of the LZ. On short final to the LZ, the RPM warning light came on because of loss of RPM. The aircraft commander pulled in more torque in an apparent effort to keep from falling through. WO Quimby was monitoring the instruments, and called out the readings to LT Feldman. The torque meter continued to rise and at its peak reached 55 pounds. At this point the RPM bled off as low as 6000 at full beep. Full left pedal was applied at the bottom of the approach and the aircraft began turning to the right rapidly and the tail rotor struck a tree, knocking the tail rotor off. The aircraft commander states that the wind had changed to a quartering tail wind near the end of the approach. After the impact of the tail rotor, and subsequent loss of it, the aircraft made a 360 degree turn and crashed into the ground, coming to rest partially on its right side. The Chaplain was thrown out of the aircraft along with some water cans on impact. The crew chief and gunner exited by normal means and the aircraft commander and the pilot exited through the broken left windshield. It should be noted here the passengers had no restraining device and the water cans were not tied down
