Just doing a 'copy & paste' of U.S FARs with minor modifications could easily solve the problem.
But we are smarter than yanks aren't we?
To list a few nonsense CASA land has IMHO:
1) NVFR rating
why bother to have separate NVFR? Just make it a part of PPL training.
2) MECIR, SECIR and their renewals
Seriously? What's up with this renewal? Why can't we just let 6 instrument approaches and 6 hours of IFR flying every 6 months be one of requirements for automatic renewal?
3) Retractable Gear and CSU
I don't remember seeing 'retractable gear' training program in U.S. As for CSU, it is covered in multi-engine rating training.
4) Lower fees
US FAA Inspectors don't charge a cent for your checkride. Designated Pilot Examiners do (around $400) but they buy you a lunch if you pass. Oh yeah, FAA doesn't charge you anything for license issuance.
God Bless America.
Lord have mercy on CASA.
