An aircraft landing at Mawlamyine Airport experienced a runway excursion following touchdown on a wet surface, resulting in multiple fatalities.
What happened
During an arrival from Yangon, the flight crew attempted to land at Mawlamyine (Moulmein) Airport. Upon touching down on a runway that was covered in moisture, the aircraft struggled to decelerate sufficiently within the available pavement length. This lack of braking effectiveness led to the plane overrunning the end of the runway before eventually coming to a halt.
The incident resulted in six fatalities among the passengers on board. Additionally, the accident caused injuries to 39 other occupants of the aircraft.
Findings
The presence of a wet runway surface contributed to the difficulty in stopping the aircraft.
The aircraft failed to remain within the boundaries of the runway during the landing roll.
Probable cause
The aircraft was unable to stop on the wet runway surface, leading to a runway overrun.
