Circumstances:
The aircraft was completing a cargo flight from Yangon to Sittwe, carrying four passengers, four crew members and a load of construction materials. The descent to Sittwe Airport was initiated in marginal weather conditions with limited visibility due to low clouds. Following a radio contact with ATC, the pilot reported 3,500 feet on approach. Shortly later, the aircraft struck the slope of a hill (270 metres high) located 12 km short of runway 29. The aircraft was destroyed and all eight occupants were killed.
Probable cause:
Controlled flight into terrain after the crew descended below the MDA in IMC conditions.

Circumstances:
While descending to Mergui Airport, the crew encountered poor weather conditions with heavy rain falls. On short final, the aircraft lost height and struck the ground about 250 metres short of runway 18. On impact, the undercarriage were torn off and the aircraft slid for few dozen metres before coming to rest in a 1,2 metre deep excavation located short of runway threshold. Eight passengers were killed while 16 others were seriously injured.
Probable cause:
It was reported that the crew initiated the approach while maintaining a visual contact with the runway. At an altitude of 1,500 feet, visual contact with the runway was lost due to heavy rain falls and the aircraft lost height and struck the ground in a relative flat attitude. The horizontal visibility at the time of the accident was estimated to be 1,500 metres and it is possible that the aircraft encountered windshear.

Circumstances:
The approach to Kawthaung Airport was completed in poor weather conditions with rain and a horizontal visibility down to one km. The aircraft approached too high and landed too far down a wet runway that is 1,260 metres long. Unable to stop within the remaining distance, the aircraft overran at a speed of 80 knots then ended up in a river bank. All 45 occupants were rescued, among them seven passengers were slightly injured.
Probable cause:
Wrong approach configuration on part of the flying crew who completed a too high approach and landed too far down a wet runway, causing the braking distance to be insufficient. At the time of the accident, the runway surface was wet and the braking action was limited.

Circumstances:
Just after takeoff from runway 03 at Yangon-Mingaladon Airport, the aircraft banked left then struck a tree located about 150 meters past the end of the runway. It descended and crashed in a nose-down attitude of 3°, bursting into flames. Three occupants were injured while 26 others were killed. At the time of the accident, the visibility was poor due to thick fog.
Probable cause:
The assumption that the loss of control during initial climb occurred after the pilot-in-command suffered a spatial disorientation was not ruled out.
