Cant be that hard to tear a B747 apart can it???
You are right. Putting it back together is the hard bit
If the work is done in Australia at least you know the a/c will be pulled apart, inspected, and put back together. O/s there are to many examples of work just being signed off i.e. Flight control functional checks with no power available on the a/c, NDT inspections with no access provided, etc., etc., etc.
P.S. If you live in AVV, why would you want staff travel?
