The relevant issue is probably not Aero Tropics alleged landing at a disused airstrip and getting bogged – although in this day of GPS it is hardly excusable, especially as I understand the mail service is operated as remote area RPT – but why CASA Townsville took regulatory action against the previous mail contractor who landed at the correct airstrip and became bogged, after receiving an allegedly incorrect strip report?
Are 500S Shrikes still being operated IFR in the Cape and Straits at the Australian only VFR max gross weight?
