The description by spanners of some Tristar jobs as "juicy" is one of the more polite terms I've heard. I could add a couple more, mixer-ejector changes or replacing a pack valve in the sweatbox that was the MESC on a summers day. That said one of the main reasons that the L1011 was reviled in such a big way was that it was just "different". It took a bit of getting used to but once you got the hang of it wasn't too bad. FRM's and FIM's, used properly, were a big help and some of the system BITE equipment was OK too ( what was that thing called for tracking down overheat loop problems along the pneumatic ducts? Lockheed raved about it but I never saw anyone ever using it, forgotten the name now). The early aircraft lacked performance and range but later versions, the -200, -250, and -500 were pretty good aeroplanes. Flight deck had loads of room and was well laid out, passengers liked it for the wide airy cabin.
