Definitely not the legal solution, but I'd be curious to know how heavy a Dash-7 could be on take off to have an engine failure at V1 (I suppose a lower speed would actually need to be used) and, using the slope and power from three good engines, still get airborne (which I am assuming is possible). Also how well it would fly afterwards at that weight (ie can it make a normal flight to it's base or would it require taking an alternate, lower, route home?). If they are hauling fuel and returning empty or with empty drums, I would be quite surprised if they could not safely depart (but yes, safe =/= legal).
If it can get airborne on three and fly home, it would be far safer than a Caravan or other single engine plane losing an engine in the middle of the take off roll and crashing/going off the end. But I doubt they could ever convince a bureaucrat to accept that it improves or maintains the current level of safety despite being outside the normal rules.
Sadly the easiest solution would probably be to pay off the DGCA officials...
