As an S61 pilot, with experience on both the 212 and the AS332, I would like to raise a couple of points. First of all, with 5000 ft of runway remaining, I would reject, unless I was on a base check. Even then, if it was for real and not induced, I would still reject. As aircraft captain, the ultimate decision is yours. Secondly, the 212 section of the ops manual states, I seem to recall, that when operating over inhospitable terrain, that an automatic reject should not be carried out following an engine failure, but the captain should assess the fly-away characteristics of the aircraft. Finally, IMHO, a second call of "committed" would only serve to complicate things.
