Since October 2009, American safety rules for aircraft parts designed in the US automatically apply in Australia under regulation **CASR Part 39.001A** (the Civil Aviation Safety Regulations).\n\n**Who this affects:** Owners and operators of aircraft fitted with Hartzell variable pitch propellers.\n\n**What you need to do:** Follow the requirements in the FAA directive instead of the old Australian rule.
