Victor-2 You have no idea mate. Doctors would be the only ones who would come close to the amount of study and proficiency required by LAME's. I would suggest that Medicine is probably harder to complete than being a LAME however once you have finished your 8 odd years of study for medicine the pressure is off in terms of study. For pilots and/or LAMES it never ends.
I would love to see to pilot/LAME type testing and reviews brought into other industries and just watch them all blow up. Imagine if you made doctors or lawyers do quarterly exams and practical reviews. They would be up in arms!! Let's make Judges do 6 monthly law exams. That's probably why they are self regulated anyway.
Let's have a open discussion about CRM and self reporting in Medicine...that worked really well didn't it!!
In terms of work proficiency and competency no industry in the world anywhere comes close to aviation. No one.
As the saying goes 'Doctors can bury their mistakes. Pilots are buried in theirs'.
