ATV says the plane approached from the wrong direction. Also it was the same plane that skid previously in Bangladesh. May be a pilot error.
Nepal definitely needs to invest in modern ILS for the airport.

As far as I have read the news it appears that the pilot deliberately did not follow the direction given by the ATC. It could not be understood why the pilot opted to land from the north side which is little tricky in Kathmandu airport. As per the news, the aircraft had no technical issues before landing. The reason for this crash appears to be a pilot error.
