The crew departed Saigon on a supply dropping mission to An Loc. While flying at low height and high speed, the airplane was hit by enemy fire. The crew elected to return to Saigon when few minutes later, the right wing caught fire. The captain attempted an emergency landing when the airplane crashed in flames in a swampy area. All five occupants were rescued while the aircraft was destroyed.

En route from Cubi Point NAS to Saigon, the airplane crashed in unknown circumstances into the South China Sea, killing all four crew members.

While descending to Nha Trang Air Base on a flight from Saigon, the crew encountered poor weather conditions with limited visibility and a low ceiling at 2,000 feet. On approach at an altitude of 4,600 feet, the crew failed to realize his altitude was too low when the right wing struck trees. Out of control, the airplane crashed in flames in a wooded area located on the slope of a mountain, some 25 km southwest of the airport. Due to poor weather conditions and the fact that the aircraft crashed in an inaccessible area, the crash site was reached nine days later only. The wreckage was found about 150 feet below the summit and all 79 occupants have been killed. At the time of the accident, ceiling was broken at 2,000 feet and the horizontal visibility was estimated to 1,500 meters.

Apparently following fuel problems (fuel exhaustion ?), the crew was forced to reduce his altitude and to attempt an emergency landing. The airplane crash landed on a beach located in Quy Nhơn. There were no casualties but the aircraft was written off.

While descending to Huê Airport, the crew was instructed by ATC to divert to Đà Nẵng Airport due to poor weather conditions. While approaching Đà Nẵng at low height, the airplane struck a mountain (970 meters high) located near the Cloud Pass, about 17 km north of the airfield. A passenger and three crew members were killed.
