Beschrijving:
A Xian MA60 passenger plane, registered XY-AIQ, sustained damage in a runway excursion accident at Mong Hsat Airport (MOG), Myanmar. There were 55 persons on board, two were injured.
The airplane operated on a domestic flight from Yangon (RGN) to Mong Hsat (MOG) via Heho (HEH) and return. The flight left Heho on the return leg at 11:10. The first officer, who was on line training, was Pilot Flying on this leg.
When the flight arrived near Mong Hsat the weather was fine with a visibility of about 8 km. The aircraft touched down on runway 12 with an indicated airspeed (IAS) of 144 knots. The airplane could not be stopped and overran the runway at an IAS of 40 knots. It collided with a tree stump and crossed a drainage ditch located 110 m from the runway end. The aircraft turned 80 degrees left and came to rest with a collapsed left hand main landing gear.
