Shortly after takeoff from Saigon Airport, while in initial climb, the twin engine aircraft went out of control and crashed inverted in a huge explosion. All three occupants were killed. It is believed the aircraft was shot down by enemy fire.

On final approach to Saigon Airport, the aircraft was shot down by enemy fire and crashed few km short of runway. The aircraft was destroyed and all 16 occupants were killed. The C-123 was used on a MACV-SOG mission. The Military Assistance Command, Vietnam Studies and Observation Group (MACV-SOG) was a joint service high command unconventional warfare task force engaged in highly classified operations throughout Southeast Asia. The aircraft had no standard markings on it, but were painted with a unique camo pattern of low-reflectivity black, green and brown paint. The aircraft was rigged with pylons on it. All aircraft were sanitized as well as the nationality and individuality of those on board.

After landing on a wet runway at Muang Hein, in the suburb of Saigon, the airplane skidded and veered off runway before coming to rest. There were no injuries but the aircraft was written off.

Shortly after takeoff, while climbing, the left engine failed. The crew was able to feather the propeller and elected to return for an emergency landing. While turning to the left, the airplane stalled and crashed in a rice paddy field. All 15 occupants were killed.

The aircraft was engaged in a flare drop mission and was carrying four Vietnamese observers and four crew members. While cruising at low height, the airplane was shot down by enemy fire and crashed about 104 km south of Saigon. All eight occupants were killed.

The crew was dispatched from Saigon to Đắk Tô Airport to deliver various goods and supplies. After touchdown at Đắk Tô Airfield, the airplane struck a concrete block in the center of the runway, lost its undercarriage and came to rest. All six crew members were unhurt while the aircraft was damaged beyond repair. It was reported the crew was supposed to land at the old Đắk Tô Airfield but was mistakenly dispatched at the new airport of Đắk Tô which was not already open to traffic while still under construction.

En route from Saigon to Buon Ma Thuot, the crew encountered poor weather conditions and due to low visibility, the captain decided to reduce his altitude to establish a visual contact with the ground when the airplane struck trees and crashed in a wooded area. The accident site was located three days later and all four crew members were evacuated by a US Army helicopter. The aircraft was written off.

The crew was performing a leaflet dropping mission from between Saigon and Đà Nẵng. The airplane crashed in unknown circumstances in a mountainous area located near Bảo Lộc, killing all nine occupants.
