re:
With the gov't and maoist declaring ceased fire and trying to solve the problem through dialog, things are begining to look positive ( although very hard to say at this point).
DHC-6/300 's are being replaced with Do-228 by many operators, with "Sita Air" being the latest to start its domestic operations. Other operators such as Shangrila Air, Skyline, Gorkha and Cosmic have and are planning to bring out many Do-228.
If you have or are willing to get a Do-228 rating you may stand a chance. however, It would be wise to contact the operators before jumping in to get the rating.
