Ngineer hit the nail on the head.
I couldn't have put it better myself. CASA have engineered a solution for at least 20 years of neglect to the LAME system. Instead of updating the antiquated exam questions and encouraging AME's to get licenced, they did nothing for 3 decades.
If they keep QANTAS happy with Part 66, they keep aircraft maintenance out of the public eye. It's purely a system designed for large airlines to get people licenced. Grrr.
