General practice in my company seems to have been that when in doubt the engineers have advised a return above MLW. In this kind of event, runway length permitting, I'd have no qualms whatsoever about shutting down the faulty engine and then performing a landing above MLW, and I doubt the management would find fault with that course of action. I think MaxBlow is suffering from the effects of a management which say money and not safety as the most important factor.
