A quick check of the IOSA web page shows the neither Qlink or Cobham comply with IOSA or report to IOSA. That means that the jet operation is and will be operated to a standard where the recognised bench mark for auditing and operational safety standards is not audited by an IOSA representative. If Joe Punter buys a ticket on Virgin/Qantas/Jetstar then he knows these airlines meet the IOSA standards of operation and are audited on a regular basis, unlike Cobham. Will this become public knowledge and does CASA really care?
