Circumstances:
On approach to Phnom Penh-Pochentong Airport, the crew encountered poor weather conditions and limited visibility due to heavy rain falls. Unable to establish a visual contact with the runway, the captain initiated a go-around procedure. Few minutes later, on a second attempt to land, the captain continued the approach below the glide and passed the MDA. The flight engineer, the copilot and ATC as well warned the captain that his altitude was insufficient but he failed to correct the situation when the aircraft struck palms, stalled and crashed in a rice paddy field located 300 metres short of runway. A boy aged one was injured while 65 other occupants were killed.

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:
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.
Probable cause:
It is believed the aircraft lost height on short final due to an insufficient speed.
The following contributing factors were reported:
- Poor planned approach on part of the crew.
- Poor crew coordination.
- Lack of supervision and crew cross checks.

Circumstances:
The approach to Bangkok-Don Mueang Airport was initiated in poor weather conditions with a reduced visibility due to heavy rain falls. On final, the aircraft was too low when it struck the ground and crashed about 6 km short of runway. 14 occupants were rescued while 76 others were killed. The aircraft was destroyed.
Probable cause:
It was determined that after passing the outer marker, without visual contact with the ground due to heavy rain falls, the crew passed the decision height when the aircraft struck the ground and crashed. A loss of altitude caused by possible windshear is not ruled out.
