For example the Fuji FA 200 has no fatigue index here in EASA, but in Australia I found this:
http://www.comlaw.gov.au/Details/F20...f-8bbf0c6d8bd7 it says to retire every Fuji FA 200 after 1700 aerobatic flying hours. Why would this hold in Australia but not in Europe?
Australia's old unique airworthiness certification requirements had fatigue life requirements long before they were included in FAR 23 so many types were trapped by this when the first of type was imported, not just aerobatic aircraft. Lifed items controlled by ADs.
Decathlons here in Aus have lifed components that are unique to Aus.
