One of my many L-1011 stories:
I was working on the production line as a leadman on the leading edge slat crew. We were prepairing to hang the slats on the second Air Canada (AC) Tristar, when one of the AC inspectors found a repair on the number 3 left hand outboard slat. It was a small 4" square, flush patch on the upper skin, the repair had been accomplished at the vendor and approved by Lockheed. But AC did not want it.
One of the design engineers out of Burbank that worked with on the leading edge of the wing happen to be British, when we explained our problem to him, he had us take the slat off the Court Line aircraft that was just ahead of the Air Canada plane on the production line and put it on the Air Canada plane. We then installed the patched slat on the Court Line plane. I asked what if Court Line complain and he said "I speak their language and can I talk them into anything". We did the swap and never heard another word.
