A high proportion of accidents in the KTM area are (as has already been mentioned) CFIT related. However most of the accidents that I see hitting the aviation press are linked to small Nepalese operators that operate commuter sized aircraft.
Such aircraft may not have:
• EFIS/FMS
• EGPWS
• Terrain mapping on the ND (or EHSI!) - not too sure if QR have this on their A320s but I have seen it with other operators.
Looking at those stats above, the odds will dictate that operating an Airbus into KTM is safer than for example a Twin Otter.
However I must take my hat off to Necon Air in Nepal. I flew as a pax in one of their Hs748s back in Spring 2000. The flight deck 'curtain' was open and I was sitting at the front and nearly jumped out of my seat when I heard 'TRAFFIC TRAFFIC' being barked out! Not due to the close proximity of another aircraft, but I was astonished to see a third world commuter operator making the effort to equip its fleet with TCAS.
