While descending to Nha Trang Airport, the crew encountered poor weather conditions with limited visibility due to heavy rain falls. On approach, the aircraft deviated from the W13 airway by six km when it struck trees, lost height and crashed on the slope of a mountain located 350 metres, about 33 km southwest of Nha Trang. The wreckage was found eight days later at an altitude of 970 metres. A passenger was seriously injured while 30 other occupants were killed. At the time of the accident, weather conditions were poor due to the presence of typhoon 'Forest' approaching the area.

During the last segment on approach to Ho Chi Minh-Ville-Tan Son Nhat Airport, at a height of about 30 feet, the aircraft lost height, causing the left main gear to struck the ground short of runway threshold. The aircraft then landed hard and came to a halt on the main runway. All 79 occupants were evacuated, among them five passengers were injured.

On approach to Ho Chi Minh-City Airport, the crew encountered below minima weather conditions but the captain decided to continue. On short final, as the aircraft deviated from the approach path, the right main gear struck the ground 114 meters short of runway and was torn off. The right outer wing was damaged as well as the propeller n°4 and both hydraulics systems. The crew decided to return to Cam Ranh Bay Airport. Upon landing, the crew feathered the propeller n°1 and after touchdown, the aircraft veered off runway to the left, hit obstacles and came to rest, bursting into flames. Three occupants were seriously injured while 31 others were killed.

While parked at Ho Chi Minh-City Airport, the airplane was hijacked by a Vietnamese passenger.

The airplane was engaged in a humanitarian flight, taking part to the 'Operation Babylift', a mission consisting to bring Vietnamese orphans back to the US in the few remaining days before the Republic of Vietnam fell. At 1603LT, the airplane departed Saigon-Tan Son Nhat Airport bound to the east. Twelve minutes later, while cruising at an altitude of 23,000 feet over the South China Sea, a technical issue occurred on the rear access ramp doors followed by a rapid decompression of the cabin. A crew member fell out of the airplane and shortly later, the access ramp door detached and fell into sea as well. The captain contacted ATC, declared an emergency and was cleared to return to Saigon Airport. At that time, two of the four hydraulic systems were out of order and control and trim cables to the rudder and elevators were severed, leaving only one aileron and wing spoilers operating. Nevertheless, the crew was able to descend to runway 25L when the rate of descent increased to 4,000 feet per minute. The airplane struck the ground a first time at a speed of 250 knots about 4 km short of runway 25L, bounced for three seconds and then crashed 500 meters further in a rice paddy field. The aircraft disintegrated on impact and debris scattered on a wide area. There were on board 149 orphans, 10 members of a medical team, 155 military personnels and 16 crew members. It was reported that 141 orphans were killed as well as six soldiers, five crew members and three of the medical team. The United States Navy amphibious cargo ship USS Durham, frigate USS Reasoner and command ship USS Blue Ridge were assigned to search for the flight data recorder in the South China Sea. The recorder was found and US Navy ships and helicopters also discovered debris from the doors in the South China Sea as well as the body of a crew member.

While cruising at an altitude of 11,000 feet en route from Vientiane to Saigon, the crew informed ATC about his position over PE5 on the G67 airway when contact was lost. The airplane spiraled to the ground and crashed in a mountainous area located about 25 km southwest of Pleiku. The aircraft was totally destroyed and all 26 occupants have been killed, among them a Swiss citizen in charge of the medical missions of the Red Cross in Vietnam.
