Sadly I believe there is negative public/management perception of LAMEs. You have only got to look at the way the Pilots swan about the airport even in their civies with ties on etc. They can be total numpties, but they look the part.
Couldn't agree more about the new gen LAMEs reliance on the FIM, if you were to believe boeings FIM you'd be replacing wiring before the most obvious component.
If somebody could put up a cost analysis to management (that they could understand) then maybe we could prove the real worth of a properly trained, experienced LAME.
