Accident Summary:

The aircraft was on a resupply mission. It took off from LZ English with a load of passengers and cargo going to LZ Hawaii, a fire support base west of LZ English. After landing at Hawaii, the aircraft was loaded again and took off to go to A Company 2/503rd with a load of passengers and rations. The pilot was flying the aircraft when it arrived over the LZ, which was on the side of a ridge line generally running north and south. The LZ was cut out of a large area of small trees and brush that was surrounded by much taller trees. The north side of the LZ was next to the tall trees and the approach was begun by the pilot to the brushy area to the south of the LZ. The pilot had circled the area and the troops on the ground had thrown a smoke grenade which had indicated a no wind condition, although the prevailing wind was 10-12 knots from the south. The pilot therefore made the approach over the relatively open area south of the LZ. On final approach, the aircraft commander took control of the aircraft and came to a hover over the sloping brush area about 50 meters south of the LZ. The torque at this time was 38 pounds and RPM remained constant at 6600. The aircraft was then hovered into the prepared LZ with no problems and unloaded. The aircraft was loaded with 5 US troops without packs, 1 Vietnamese, 2 cargo nets, a chain saw, a can of oil and gas, and 2 cases of dynamite with fuses. The aircraft commander brought the aircraft to a hover and the RPM continued to drop. At 5200 RPM the aircraft had 35 pounds of torque and 6600 RPM. The aircraft had 600 lbs of fuel on board at this time. The aircraft commander started backing the helicopter off the pad to turn around and take off to the south. Approximately 20 feet from the pad, the RPM bled off to 6200 with 98% power and 39 pounds of torque. The aircraft began to settle and could not make it back to the LZ. The aircraft commander then stabilized the controls and beeped the RPM full up but the aircraft commander turned the aircraft to the right with the cyclic and kicked full right pedal in an attempt to gain RPM. The aircraft then traveled down the 20-25 degree slope to a point about 200 meters south east of the LZ where the aircraft commander flared, zeroed the airspeed and used the remaining RPM to cushion the aircraft as it crashed into the small trees and brush on the side of the slope
