Circumstances:
On 10 June 2013, at 6:55 local time, Myanma Airways MA-60 (XY-AIP) departed from Yangon to Mawlamyine- Kawthaung and back with 4 crews and 27 passengers. During climbing, hydraulic pressure low warning (LEDPL), intermittently illuminated and aircraft returned back to Yangon. After snag rectification, aircraft departed to Mawlamyine at about 10:15 local time. During final approach, while landing gear down hydraulic pressure low warning illuminated and disappeared at aircraft parking. At about 11:10, aircraft departed from Mawlamyine with 4 crews and 60 passengers. During the route Mawlamyine to Kawthaung, no warning light illuminated. While approaching to Kawthaung RW, PIC check hydraulic quantity and flap down to 5°, landing gear down and final turn to runway 02. During final approach, LEDPL warning light was come again. PIC set flaps 15° to 30° respectively, but he noticed flaps position was not fully extended. As soon as aircraft touch down, PIC apply reverse power at about 2,500 ft from runway end. After recognition of aircraft swing, PIC changed power lever to GI position and applied brake and changed nose wheel to taxi mode and steering. Aircraft cannot able to steer and veer off left side of runway at about 3,200 ft. Firstly aircraft stroke two fence pillars with propellers and nose wheel, then aircraft turned 90° to left and stopped after striking to tree with left wing. There was no injury to crews and passengers due to accident. The aircraft was damaged beyond repair.
Probable cause:
Primary cause:
- During landing roll, due to hydraulic system pressure low, nose wheel steering mechanism and braking action are not effectively operated and aircraft veer off runway left side.
- PIC did not operated the emergency hydraulic pump while hydraulic low pressure warning come on.
Secondary cause:
- Hydraulic system pressure low due to hydraulic tank fluid level more than normal and tank pressurize compress air line filter blockage.

Circumstances:
On 16 May 2013 at 08:00 local Time, Myanma Airways MA-60 aircraft registered XY- AIQ (MSN-0808) departed Yangon International Airport (VYYY) to Monghsat Airport. For this flight captain assigned FO to line training (Command) pilot and aircraft landed to Monghsat at about 09:25 local time. After passengers disembarked and boarded, aircraft departed to Heho at 09:55 local time and landed at about 10:40 local time. Aircraft refueled at Heho and departed to Monghsat at 11:10 local time with 4 crews and 51 passengers. First officer was designated as the Pilot flying for this flight. Captain contacted to Monghsat ATC weather information, and aircraft climbed to 15000-ft with indicated airspeed 200 knots. Where reaching 40 Miles to Monghsat airfield, Captain request descent clearance and descent to 8000 ft. After passing transition level 125 Monghsat airfield, QNH setting and performed approach check. During approach to Monghsat airfield, weather was fine and visibility was 4-5 Miles (8- km). When reaching 3 Miles distance to runway 12, approach speed was 120 knots IAS. At about 11:47:59 local time, aircraft first touchdown to runway 12 with IAS 114 knots, vertical speed -288, flap 30 degree. During landing roll, aircraft over run to runway 30. At about (11:48:33) local time, aircraft struck to tree stump with IAS 40 knots and passing across to water drainage (gutter) located 110 meters from runway 30. After striking, aircraft turned to left 80 degree and came to rest. Cabin crews performed emergency evacuation, one passenger suffered serious injury, other one suffered minor injury and 53 of the occupants were survived. One passenger was serious injury ( back pain) and one passenger was minor injury (shoulder joint injury) due to accident. The left main leading gear and nose landing gear strut broken, left engine propeller blades broken, left wing tip broken and lower fuselage frame dents. The aircraft was substantially damaged.
Probable cause:
Primary Cause:
- During landing roll FO retracted PIA to GI position, its remain above Ground Idle position (36.8/ 36.6) degree. After (18) seconds flap position changed to retract and both engines torque start to increase.
- Aircraft IAS unable to rapid decelerate during crews applied braking.
Secondary Cause:
- Both crews are not initiated power lever reversing position.
- Crews need multi-crew operation.

Circumstances:
Following an uneventful flight from Yangon, the crew completed the approach to Sittwe Airport in poor weather conditions. The aircraft landed hard on runway 11, causing the right main gear to collapse. The right wing struck the ground and was partially sheared off. The aircraft went out of control, veered off runway to the left and came to rest against a fence. Three occupants, among them the captain, were slightly injured and the aircraft was damaged beyond repair. At the time of the accident, the runway threshold and edge lights as well as the VASIS were unserviceable.

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.
