While approaching Nha Trang on a flight from Saigon, the pilot informed ATC about an explosion on board and that control was heavy. The hydraulic system failed so the undercarriage must be lowered manually. The captain decided to perform a low pass over the runway to check the landing gear with ATC. That made, the crew completed a nose high and flapless landing shortly later. After touchdown just over the threshold, the crew activated the reverse thrust systems when the airplane became airborne. So the throttles were closed and the aircraft landed again but too far down the runway. Unable to stop within the remaining distance, it overran, struck a concrete pylon and several obstacles before coming to rest in flames in a popular area. Ten passengers and 24 people on the ground were killed. The aircraft was destroyed by a post crash fire.

Shortly after takeoff from Saigon-Tan Son Nhat Airport, while climbing, an engine failed and caught fire. The pilot lost control of the airplane that crashed in a huge explosion. Six of the 10 occupants were killed. At the time of the accident, the airplane was carrying a load of ammunitions.

While cruising at an altitude of 9,000 feet on a flight from Saigon to Đà Nẵng, the right engine failed. The crew was unable to feather the propeller nor to maintain the assigned altitude so the captain decided to divert to Buôn Ma Thuột Airport. While descending, the airplane went out of control and crashed at an altitude of 700 meters on a plateau located 18 km from the airport. The aircraft was destroyed and all 23 occupants were killed, among them two US civilians.

Shortly after takeoff from Khâm Đức Airfield, while in initial climb, the aircraft was shot down by North-Vietnamese soldiers who were conducting an assault of the airbase. The aircraft went out of control and crashed in a huge explosion some 4 km east of the airfield. All 155 occupants, South-Vietnamese soldiers with their wife and children, were killed.

Several C-130 Hercules transport planes were used to fly supply runs to an airstrip at A Loui. The aircraft approached under low clouds, airdropping the supplies from the rear ramp. Several aircraft were hit by enemy ground fire. The 21st supply aircraft was hit by .50 calibre and 37 mm ground fire. A fire erupted in the cargo hold and the crew attempted to jettison the burning load while the pilot attempted a forced landing on the airstrip. The airplane struck trees, crashed and burst into flames. All eight occupants were killed, among them two photographs.
