Accident Summary:

On 14 August 1971 aircraft, UH-1H, 723 departed Chu Lai at about 08:30 hours on a resupply mission. The aircraft had flown for about seven hours and had refueled four times with no mishaps. At about 14:00 hours the aircraft was refueled for the fourth time at Tien Phuoc. Shortly after 1400 hours the aircraft was on a normal approach to LZ West. At about 20 knots, 50 to 100 feet and 30 pounds of torque the aircraft began to bleed RPM. In an effort to gain RPM the aircraft commander lowered the pitch and tried to land short of the pad. At this time the aircraft no longer responded to pedal control. On touchdown the left skid of the aircraft caught on the elevated PSP pad and began to rock backward and to the right. The aircraft commander then pulled the remaining power in an attempt to pick up on the pad. The anti-torque control was completely negative and the aircraft spun off the pad. The main rotor struck the ground and the aircraft continued backward uncontrolled. The aircraft came to a stop about 40 meters from the pad facing 180 degrees to the approach path.

Accident Summary:

The aircraft commander, pilot and crew departed Chu Lai Army Airfield in UH-1H 69-15762 at 0845 hours 16 June 1971, for a 5th ARVN C&C mission. the day was uneventful until around 1645 hours. Mr Michael Carlisle, the aircraft commander, was flying and set up his approach from east to west so as to land into the wind. On short final the aircraft commander felt a feedback in the cyclic control and a stiff collective. With the help of his pilot, Mr Carlisle landed the aircraft. As UH-1H 69-15762 touched down its main rotor blade struck the stabilizer bar of a VNAF aircraft parked on a pad adjacent to the touch down point. the blade strike set up a severe vibration in aircraft 69-15762, causing it to bounce away from the VNAF helecopter. The aircraft had seven passengers and four crew members at the time of the accident.

Accident Summary:

On the morning of 4 August 1971, aircraft 69-15759 departed the 174th AHC in Chu Lai on a direct support mission. The aircraft was flown for four hours and thirty minutes, supplying various fire support bases. On the last sorties, the aircraft departed Quang Ngai enroute to Hill 411, the last trip of many to that location. The aircraft had a poor hover check of 35 pounds of torque, and the N1 was 97.0% at approximately 38 degrees centigrade. The aircraft made a takeoff and approached Hill 411. The aircraft commander started his approach and began to bleed RPM as power was increased prior to landing. He lowered collective in an attempt to regain RPM. This did not result in an increase in RPM. The aircraft was approximately ten feet above the ground and approximately twenty five to thirty feet from the pad when the aircraft commander elected to attempt a go around. The RPM was not sufficient to accommodate the increased demand for power for the go around, and the aircraft fell through, striking a bunker, sliding and rolling over while traveling down a hill. The personnel on Hill 411 called emergency Dust-Off for the crew. There was no need for a defensive perimeter, as the aircraft landed within the perimeter of Hill 411. There was no fire, however there was fuel leakage. All crew members were wearing the required protective clothing to include; leather boots, flight helmets, nomex flight suits, and gloves. All radios and secure gear were salvaged.
