sir: instead of pricey light twins that offer little advantage, why not put as-350b3 or 407's on line, you could field 4 fully equipped for the price of two light twins ( md 902 / 135 ). all the aforementioned airframes can do the job. but with the 412 on staff, why not look towards an airframe that operate in tight areas, loads of power and all the capability of the light twins at half the cost. the most capable aircraft in the world is not much good if it is u/s waiting for spares etc. going with the 350 or 407 would allow you the luxury of actually having a true backup a/c 24/7. as for capability, other than full engine failure, what can a 902 / 135 do better than the as-350b3
