Death spiral? OP is asking about costs. And that could cause a death spiral I guess.
Out in the GAFA, the maintenance seems to be done to the owners whimsy.
Maybe there needs to be a tightening up of standards, and a separation of private and "commercial" operations and maintenance.
Oh look CASR 1998 is nearly here.
and the responsibility for not having the SB carried out is the operators. Am I wrong yr right?
Now there is pause for thought, if an AD or other mandatory requirement is missed who bears legal responsibility, should an accident occur?
