If they are a lease, then questions raise to 'whom' pays the aircraft rental?
Sorry, S320, you've lost me. What does it matter by whom the lease is paid, as long as it is?
The aircraft is VH registered (and THAT would have been a rigmarole knowing the hoops CASA put you through), and, it will have to be on someone's AOC and therefore comply with all that goes with that - what is your concern?
