Will have to have a trawl through the Civil words over the next week .. about time I refreshed my familiarity in any case ... before I wax lyrical. No point making a fool of myself without having done my homework.
My turn for a question
Generally, at the formal level, CASA isn't overly interested in State aircraft, per se. However, on the side, where such State aircraft are civil Types, the interest is fostered for sensible fleet statistical information - I am aware of one or two events in respect of such aircraft where the information led to civil Industry action.
I can't bring to mind any situation where CASA fronts up with a presumption of responsibility for such aircraft.
I’m also aware that engineers have an almost limitless genius to set up all kinds of arrangements
.. which is not bad for the boring old pharts that most experienced engineers tend to end up becoming ...
Will have a ponder over the rule books over the next week or two and come back to your comments above ..
