And another thought: just few weeks ago EASA allowed distance learning for maintenance technicians - for now basic license course and Type rating theory, but I believe regulations are in the works that also practical part of type rating course (or most of it) will be allowed to be completed sitting behind computer and moving - "doing" things on the airplane by moving cursor/buttons etc. on the screen. Current COVID-19 situation accelerating this even more.
This on top of the current situation, where most of newbie licenced engineers get their EASA Part-66 licence by doing exams only-meaning ticking a, b, c boxes and completing 5 years practice work in maintenance environment - with no tutorial/mentoring etc. required/defined/prescribed. No wonder someone recently put 37 times more biocide in an A-320 fuel tank than prescribed by Maint. Manual, without blinking an eye. Where is this going?
