I'm not saying aircraft fix themselves. I'm saying generally these days aircraft tell you where to start looking when something goes wrong, especially the new generation of aircraft. 99% of the time you're not breaking out the WDM let alone a megger.
With regards to training standards, of you feel that an entire apprenticeship can't be condensed into 6 weeks or so of remedial training by outside MTO's, bring the issue up with CASA. The MTO's didn't sign themselves off as component, CASA did. They set the standard, they must be happy with the end result.
With regards to inadequacy, don't think the rest of the workforce doesn't roll their eyes when the superiority complex of a sparky on the couch rears its head, over and over. Please tell us how good you guys are over and over again. Who ticked the wrong box now?
