On final approach to Pleiku Airport, at an altitude of 1,200 feet, the airplane was hit by enemy fire and crashed about 5 km from the airfield. All five crew members were killed. The airplane was performing a flight from Saigon-Tan Son Nhat Airport, carrying a load of 30,000 pounds of detonators.

Following a flare-dropping mission, the crew was returning to Tánh Linh Airbase when an engine failed on landing. The airplane went out of control and crashed. All five crew members were injured while the aircraft was damaged beyond repair.

Crashed in the Shau Valley following an engine failure. The exact date of the occurrence remains unknown (crashed somewhere in 1965) as well as the occupant's fate.

The aircraft was attempting to land at Tuy Hòa Airport under a very low cloud base when it was hit by ground fire 8 km south of the airbase and crashed killing all five crew members. The airplane, based at Nha Trang, was bringing in a load of 13 tons of aviation fuel and it was 1st Lt Smith's first mission as aircraft commander. Enemy action was never actually confirmed to have caused the loss of this aircraft which may simply have flown into high ground in poor visibility. For some reason the remains of 1st Lt Wax were not recovered and identified until December 1996.

While descending to Tuy Hòa Airport, the crew encountered poor weather conditions with rain falls. While flying at low height, the airplane struck tree tops then stalled and crashed in a dense wooded area located about 30 km east of the Tuy Hòa Airfield. As the airplane crashed in an enemy zone, it was not possible to intervene immediately and the first rescuers reached the crash site two weeks later only. The aircraft was totally destroyed and all 85 occupants were killed. At the time of the accident, the ceiling was down to 50 feet from the ground and the crew was apparently not aware of his too low altitude.

The crew was returning to Đà Nẵng Airport following a supply mission. On final approach in darkness, the pilot encountered poor weather conditions with heavy rain falls and high winds when one of the engine failed. The airplane stalled and crashed in a minefield located 1,6 km short of runway threshold. The aircraft was destroyed and all seven crew members were injured, some of them badly.

During the takeoff roll at Saigon-Tan Son Nhat Airport, the captain decided to abandon the departure and started an emergency braking procedure. Unable to stop within the remaining distance, the airplane overran and came to rest. All four crew members were slightly injured and the aircraft was damaged beyond repair.
