The T 28 endorsement was done by a well known Commercial Pilot and the Sticky signed off by a CASA FOI at Bankstown, nothing to do with AWAL.
The float rating was done by a Canadian Commercial Pilot in Western Aust and again signed off by the CASA office which was at Jandakot at that time.
Both cases were CAR 5.21 authorised by CASA prior to the Endorsement/Rating flying.
