Circumstances:

The route of the aircraft on that day was MDL- MYT- PBU- MYT- MDL- RGN. From Mandalay (MDL) on the way back to Yangon International Airport, the plane took off at 17:20.On the way the weather was not significant. For weather reason, seat belt sign was turned on the way to Yangon International Airport only one time. From Mandalay Airport up to landing phase to Yangon International Airport, first officer took control of the aircraft. At 1730 visibility was 6Km as per ATC verbal information. About 4 Km to Mingaladon Tower, clearance was obtained "Air Bagan 424 ,wind calm ,runway 21,clear to land, caution landing Runway wet, after landed vacate via Charlie" At decision height (250ft), runway was insight, runway lightings were able to be seen so the aircraft continued though there was light rain. At about 50 ft, more rain was falling suddenly consequently visibility became poor. So the pilot took over control of the aircraft. A few seconds later the aircraft made hard landing and skidded and veered off the left side of the runway to the muddy strip, came to rest about 2800ft from the threshold and 75ft from the runway edge.

Probable cause:

Primary cause:
During the final landing phase, the pilot was reluctant to perform a go-around while the plane was unstable and of bounce landing in low visibility condition.
Contributing factors:
a) The visibility was very low and the runway centerline lightings were not able to be seen intermittently.
b) The runway was wet and it was raining heavily.
c) The pilot in command took over the control of the plane from the copilot (14) seconds just before the first impact.

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.

Circumstances:

The aircraft commenced a normal take-off and when airborne, "wheels up" was selected. Since sticking of the undercarriage selector knob was experienced the radio operator was requested to operate the undercarriage safety switch. The undercarriage retracted normally and the aircraft immediately sank and struck the runway. The pilot shut off power and the aircraft slid at high speed for a considerable distance down the runway. The aircraft caught fire but all passengers and crew were evacuated safely before the aircraft was almost completely destroyed. The pilot-in-command stated in his evidence that he had no idea of the airspeed at the time he retracted the undercarriage but he was satisfied that he had the safety speed. Although 'Pilots notes' give 20 degrees of flap for take-off no flap was used in this case as the pilot felt that, in the event of engine failure after take-off, 20 degrees flap would make it more difficult to handle the aircraft on one engine. It was brought out in the evidence that in handling the undercarriage lever, which is at times awkward to operate in Dove aircraft, the attention of the pilot can be distracted from actual flight.

Probable cause:

The accident was caused by the combination of the following factors:
- The aircraft was pulled off after too short a take-off run at a low speed.
- The undercarriage was retracted too early and before safety speed was reached, whilst still at a very low altitude.
- The aircraft sank back on to the runway before the safety speed was reached. This my be due to either a thermal disturbance or to the fact that the pilot's attention was distracted by difficulty in retracting the undercarriage.
- The aircraft caught fire to the rear of the starboard engine nacelle while still sliding down the PSP runway, due possibly to the fracture of petrol pipes and electrical circuits.
- The pilot failed to operate the fire extinguishers in the engine nacelles which might have prevented the outbreak of fire. (The inertia switch of the static fire extinguishers in the engine bays were not operating due to the relatively slow acceleration.
- The airport fire tender delivered its full complement of 2,500 gallons of foam, but was late in arrival as a result of taking the unserviceable taxi track, and the equipment on it was not applied to the best advantage due to the inexperience of the crew.
- The fire burnt itself out and the aircraft was almost totally destroyed.
