Calendar time for engine overhauls
Hi all,
Looking into the costs associated with aircraft ownership. I know engines need to be overhauled according to the hourly limits imposed in the POH, but what are the rules (in Australia) surrounding calendar time limits? Scenario: I want to buy an entry level hour builder while I work toward CPL, I have found several aircraft that have in excess of 800 hours left to run before they're due for their overhaul, but they're still on the original engines from, say, 1970 so "beyond calendar time". Do I need an overhaul?
I've had some people tell me that my purpose is private, not charter, so I can fly these aircraft without an overhaul. But others have said that flight training would count as air work and therfore require an overhaul.
Can anyone shed some light here?
Thanks.
