If it's the long nose version, then correct balast is vital. Been a while since I flew a BN3, but I think they all have extended tip tanks. The transfer pumps were known to fail, so know the transfer rate! I recall too that the brakes were the same as the BN2, but you're carrying around a lot more weight. Accidently landing with a minor tailwind will burn out the pads fast. Been there, smelt that! We once had a drama with the X-feed system. With all 3 engines (260's) running, fuel was somehow being transfered into the other main tanks. Correspondence between self and the manufactuer never resolved that problem. It didn't occur on the BN2's I once flew. Overall, I'd have to say that correct ballast assuming the version described above, is critical. Never let the baggage folk pull bags from the forward locker before emptying the rear first. Makes for a good photo if this occurs, particularly if the tail-stand isn't in place!
