Circumstances:
The aircraft departed Mergui (Myeik) Airport at 1306LT bound for Yangon, carrying soldiers and their family members. While cruising at an altitude of 18,000 feet in good weather conditions, radar contact was lost with the airplane that crashed in unknown circumstances in the Andaman Sea at 1335LT. SAR operations were initiated and first debris were found at the end of the afternoon about 218 km off the city of Dawei, according of the Myanmar Army Chief of Staff. It is believed that none of the occupants survived the crash. Brand new, the aircraft has been delivered to the Myanmar Air Force in March 2016. The Shaanxi Y-8 is a Chinese version of the Antonov AN-12 built post 2010. The tail of the aircraft was found a week later and both CFR and DFDR were recovered and transmitted to the Army for further investigations.

Aircraft flight hours:

Circumstances:
The crew (five flying crew and six De Havilland engineers) were conducting a demo flight from London to Sydney to show this new jetliner to potential clients in Southeast Asia and Oceania. While taking off from runway 25 (2,500 meters long) at Mauripur Airbase, the airplane failed to get airborne, overran, hit several obstacles, went through a perimeter fence and eventually crashed in flames in a small river. The aircraft was destroyed by a post crash fire and all 11 occupants were killed.
Probable cause:
The accident was caused by the fact that the nose of the aircraft was lifted too high during the takeoff run, resulting in a partially stalled condition and excessive drag. This did not permit normal acceleration and prevented the aircraft from becoming airborne within the prescribed distance. The pilot appears to have realised that the nose was excessively high and took corrective action, but this was done too late to prevent the aircraft striking an obstruction immediately beyond the perimeter fence before it became airborne. The following factor was considered as contributory: the pilot, who had only limited experience in the Comet aircraft, elected to takeoff at night at the maximum permissible takeoff for the prevailing conditions. The circumstances required strict adherence to the prescribed takeoff technique, which was not complied with.

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.
