Synopsis
On 27 November 2018, at 09:28 local time, a Myanmar National Airlines training flight operated by a Cessna 208B Grand Caravan (registration XY-AMB) experienced a runway excursion during the landing roll on Runway 04 at Mawlamyine Domestic Airport. The aircraft had departed Yangon International Airport at 08:40 local time with nine persons on board: a pilot-in-command, first officer, flight operations inspector, two trainees, and four cabin crew. No injuries were reported.
Aircraft and Flight Information
The aircraft, a Cessna 208B Grand Caravan manufactured in 2015, was operated by Myanmar National Airlines. The flight was a training mission on the Yangon-Mawlamyine-Yangon route. Weather en route was fine, with flight level 7,000 ft.
Sequence of Events
During the approach to Runway 04, the first officer was controlling the aircraft. As the aircraft descended to 30 ft above the threshold, the first officer reduced power. The aircraft then landed abruptly with a nose-down attitude, causing the nose landing gear to break and the nose wheel to burst. The aircraft bounced approximately 25 ft from the runway. After the bounce, it landed again and veered off the left side of the runway, coming to rest on the grass edge about 1,800 ft from the threshold of Runway 04. The propeller struck the ground, resulting in twisted and deformed blades. No fire occurred.
Injuries and Damage
No injuries were sustained by any of the nine occupants. The aircraft sustained damage to the nose landing gear (broken and wheel burst), propeller blades (twisted and deformed), and the Emergency Locator Transmitter activated. The aircraft came to rest with the nose in the grass at the runway edge.
