Description

On 12 March 2018, a Bombardier DHC-8-400 (S2-AGU) being operated by US Bangla Airlines on a scheduled international passenger flight from Dhaka, Bangladesh to Kathmandu as UBG 211 left the side of the destination landing runway 20 shortly after a late touchdown after making a VOR/DME approach in day VMC. It continued through the airport’s inner perimeter fence, caught fire and was destroyed. Forty seven of the 67 passengers and all four crew members were fatally injured and the remaining 20 passengers survived with serious injuries.

Investigation

An Aircraft Accident Investigation Commission was established on the day of the accident in accordance with the Civil Aviation (Accident Investigation) Regulation (2016) of Nepal and a Preliminary Report was issued on 9 April 2018.

This Report states that the aircraft touched down 1700 metres beyond the threshold of the 3050 metre-long landing runway before veering off the runway to the left and crashing through the airport’s inner perimeter fence. It then continued along a downslope and eventually came to a stop 442 metres southeast of the initial touchdown position. It is also confirmed that the CVR, DFDR and QAR as well as recovered items including the EGPWS have been sent to the Canadian TSB for download and analysis.

The weather conditions at the time of the accident at the 4395 feet altitude airport were reported to have been a light westerly wind, a visibility of 6 to 7 km and a surface temperature of 22° C with scattered cloud at 1500 feet aal and few (1-2 oktas) Cumulonimbus cloud at 2500 feet aal over the southern side of the Kathmandu Valley where there was “thunder and lightning”.
