You better get down the hangar & do some o/t, as you know we don't do all four engines, same theory as twins. I assume safety is the reason & not that we'd be overworked doing all 4!!! Worked "big twins" in my last job so understand the old ETOPS stuff. How's life on the line, still working hard
Never seen the need for an A & P, served as "man & boy" at a certain big airline in the UK until the lure of VS (& payoff from last job) was too much to resist.
