Just curious, what did you do when your maintenance manual said no?
Or when there was no approved manual for your particular fix?
Honest question, (from a pilot) I thought this was where LAME's needed to get technical authorisation from a CASA delegate? (PE)
As I said before I have never ever worked for Qantas, so I don't know what they do, maybe they do this all the time, especially in heavy maintenance.
I have never had a problem that we couldn't either fix on site or get around somehow, like with an MEL.
Much of the time it wasn't a practical option anyway even IF we had of needed their help, especially in places like Saigon, Taipei, Moscow or even New York.
Sure it is not a problem at Qantas Sydney, maybe as someone suggested the LAMEs there rely on these PEs too much, I don't know.
