P.S Skytrans are doing yet another major overhaul of an aircraft in the open hangar in Cairns, Amazing how CASA turn a blind eye to that, considering it breaches their maintenance permission for that facility. Nobody seems to care that there is no fire supression equipment in that hangar and it is only meant to be used for light maintenance and avionics work
I find it VERY difficult to believe that Skytrans would conduct heavy maintenance in a facility so close to the public eye if it wasn't approved... You can apply to the CASA for many exemptions... this may have been one.
