Without looking at the ownership structure, the aircraft
may be protected from resale if it's on the Personal Property Securities Register which can be done by the majority owner This means if it's sold to a buyer who doesn't do their due diligence the title of the property does pass. It's not too late to register and it should refer to all serial number of engine, instruments, radios (and ADSB) in the event that it's stripped and sold for parts.
Aircraft can be easily spirited away and hidden anywhere in Australia. I know someone who'd like to locate the whereabouts of
VH-IOD PA31-350 and
VH-ALT PA30 which if I understand correctly, were somehow related to an insolvency or similar.
The
Personal Property Securities Register (PPSR) is a national online register that can provide information to help protect consumers when they are buying
personal property such as cars, boats or artworks (not including land or buildings).
