You seem a little worried there Blacksheep.The reason riggers like to call your wiring string is because you avionic types like to "string" jobs out, and in larger organisations manage to always cluster in the flightdeck.I think your underlying problem is that you realise that you don't do that much now, and that you may be pushed out of a job. In my place the avionic guys wont even take off a panel, let a lone take out a damaged screw. The C.A.A. seem happy to empower us via JAR66 to do the job. As far as "high tech" test equipment goes, I don't care how it works inside as long as it tests the system and I can get credible results.
