.....and there in lies the problem with the current " cornflake packet" license type training these days.
All about quick and cheap training rather than thorough training that has the LAME ready to take on almost any task.
Engine changes are pretty routine for an experienced LAME mind you. 787 software issues not withstanding.
That said, wasn't it the argument of group CEO that new aircraft require less maintenance? And here we have two thirds of the fleet grounded already?
Good job QANTAS pays all the bills and provides a ready made hangar.
