Circumstances:
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.
Probable cause:
Following negligences and wrong interpretation of instrument settings, the aircraft deviated from the prescribed W13 airway by 6 km until it impacted the ground.

Circumstances:
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.

Circumstances:
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.
Probable cause:
It was determined that a bomb placed in the front left lavatory exploded in flight, causing a 1,5 m hole in the fuselage and damaging the hydraulic lines.

Circumstances:
Shortly after midnight on the 28th a Combat talon C-130E-I, flown by crew S-01, took off from Nha Trang and headed at low-level towards Hanoi on a special operations mission. The aircraft was to make a leaflet drop west of the city followed by a diversionary resupply drop in the Song Da Valley in North Vietnam. Diversionary drops were sometimes made by the Combat Talon aircraft to fool the enemy into thinking that a clandestine team was working in a particular area. The aircraft made a radio transmission about four hours later indicating that the mission was progressing normally. After that message there was no further radio contact and the aircraft was posted as missing on the morning of the 29th. It was presumed that the aircraft had either been shot down by ground fire over North Vietnam or had flown into the ground as it was returning at low-level in the dark. A two-week search along the aircraft's planned route failed to reveal any sightings of wreckage. Investigations at a crash site in mountain in the Lai Châu province of North Vietnam in 1992 and 9913 failed to provide conclusive evidence of human remains. The aircraft had crashed about 51 km northeast of Điện Biên Phủ and the site had already been scavenged by villagers. However a subsequent investigation did discover some scant remains but these are still awaiting positive identification. The wreckage was found just below the summit of a high karst cliff indicating that the aircraft had probably flown into high ground as it was returning from its mission.
