Narrative:
An ATR-72-212 operated by Air Bagan was damaged in a runway excursion accident at Yangon-Mingaladon Airport (RGN), Myanmar.
Flight W9424 was a scheduled service fro Mandalay to Yangon. The copilot was Pilot Flying, while the captain was Pilot Monitoring.
It was raining as the flight approached Yangon with Cumulonimbus clouds at 1500 feet over the airport. When 4 km out, the flight was given landing clearance by ATC: "Air Bagan 424, wind calm, runway 21, clear to land, caution landing runway wet, after landed vacate via Charlie."
At decision height (250ft), runway 21 was in sight and runway lightings were seen. The aircraft continued though there was light rain. At about 50 ft, visibility suddenly became poor due to heavy rainfall. So the captain took over control of the aircraft. A few seconds later the aircraft made a hard landing, skidded and veered off the left side of the runway onto muddy ground. It came to
rest about 2800ft from the threshold and 75ft from the runway edge.

The copilot radioed a distress message, but did not use standard phraseology. The ATC controller did not appear to understand the message and was not able to give definite information and instruction to the Airport Fire Station to respond to the emergency. Therefore, the aircraft rescue and fire fighters reached the accident site after about 8 minutes.

Primary Cause
During the final landing phase, the pilot was reluctant to perform a go-around while the plane was unstable and of bounce landing in low visibility condition.
Contributing Factors
a) The visibility was very low and the runway centerline lightings were not able to be seen intermittently.
b) The runway was wet and it was raining heavily.
c) The pilot in command took over the control of the plane from the copilot (14) seconds just before the first impact.
