Gosh I'm not good at this. AdamPenrith, you have also implied Boeing's recommended maintenance schedule isn't adequate and potentially unsafe. Working in a regulated industry myself, I feel safe in assuming that published maintenance schedules are not intended to test boundary conditions.

If I were a stockholder in QF, I would be annoyed to think that money was being spent examining bolts, rivets and engines not due for inspection for many, many more cycles. Is your concern on the training of overseas engineers or something else?

On another point, I've been a passenger in one aborted takeoff of a commercial aircraft. It was a small turbo-prop with only 12 passenger seats. As far as we were concerned, all the wheels were off the ground before the pilot aborted. We slammed back to the runway and braked hard before taxiing to a halt. The pilot turned around to us, still using a mic, and said that a warning light had come on at rotation that could have meant one of three things. He'd checked them all and couldn't find anything broken, so he was going to try again.
