Thanks you 3 for your answers. So sadly nothing has changed. We too made a list of recommendations when I was there last ( period 2012/til april 2013)
PBN could easily be a (partial) solution but that would mean the airlines have to equip and that they argue it is too expensive . Add a very weak regulator and a misnister of aviation who is also the minister of Tourism.... ,not easy to solve....
But it is just the culture there. Hopefully Nepal learns something soon out of all the crashes and brings in some major changes!
Good conclusion. Unfortunately I fear that as long as the notions of " fate" and non-urgency prevails , and the tourists keep coming, it will take more than "hopes" to change things.
