Sounds like you'd make a good GA Chief Pilot... and those niggly 100 hourlies, that's a bit frequent isn't it? Plenty of life in them thar engines. Duty times? Aren't they the same as VDO hours? CAO 48 isn't really that restrictive... I could think of a few more, but sometimes the regulations are actually there to save your backside. Besides which, services like Jeppesen only reproduce procedures already established by a competent authority, so CASA has to have it's hand in...
