RMcdonal:
QF no longer has the technical ability even to modify a door lock.
Is an incorrect statement. The door locks were modified (I assume you are talking about the Dash8 doors).
I think I need to make myself clear, QF appears to no longer have the ability to
design and certify even a tiny mod to a door lock and instead had to contract it out to "Auto Avia Design" of Bankstown. Don't you keep your own professional aeronautical engineers any more??
