I just don't why people 'borrow' AOC's when it is possible to legally operate under another companies AOC, provided you go through the right process.
Its a very easy process, and as such there is NO excuse for operating outside of the regs.
If you got a misrepresentation, then go for it, claim and cash in.
The organisation I watched go through the 'operating under' AOC process was a new company, taking over an existing school with students and aircraft as the package. The organisation that permitted the start up Co. to operate under their own AOC was very helpfull, CASA were extremely helpful in ensuring that everything was in place for both companies to operate under the one AOC short term. 1 CP, 1 Chief Pilot, 2 ATO's.
CASA's helpfulness in the matter might have been encouraged in that the new start up company was going through the process of obtaining its own AOC, and had a highly respected ATO on board.
End result, whilst this was all going on, 4 GFPT's, 2 PPL's, 1 CPL and 1 Gr3 instructor rating issued, school thriving, and no student inconvenienced further than having to sign out twice.
