Synopsis
At 09:02 local time on 16 November 2016, a Cessna Grand Caravan 208B, registered XY-AMC, operated by Myanmar National Airlines, experienced a runway excursion during landing roll on runway 16 at Manaung Domestic Airport. The aircraft, on a scheduled domestic passenger flight, carried 3 crew members (pilot in command, first officer, and cabin crew) and 8 passengers.
History of the Flight
The flight departed Yangon International Airport at 07:40 local time en route to Manaung, with subsequent legs to Sittwe, back to Manaung, and return to Yangon. The en route weather was fine, and the flight level was 12,000 feet. The approach to runway 16 was normal. The aircraft touched down approximately 1,000 feet from the threshold. Shortly after touchdown, the right side of the aircraft sank, and the aircraft deviated from the runway centerline. Directional control was lost, and the aircraft veered off the runway. The nose wheel sank into soft ground on the runway shoulder at about 2,500 feet from the threshold, causing the propeller to strike the ground. The aircraft came to a stop on the runway shoulder.
