Whilst I want to give AVM Skidmore the benefit of trust and judging by performance, he must realise CASA is the Telstra of the present day (ie reactionary, inwardly focussed, anti customer/client, the aviation community are the enemy, feeling CASA are there to service it's employees first and number one, etc). A 19th century bureaucracy at it's most reactionary.
He must not join them but needs to look at them from an outside perspective and a new broom must be weilded.
As said, CASA is an international and local disgrace. And as said above, look to NZ for an example of how to do it and how not to overcomplicate it/re-invent the wheel.
