What was the reason for the kink in the leading edge, shown in the photograph in
post #1065? It couldn't have made the wing easier to fabricate or maintain.
Basically we had to recamber the wing to optimise cruise drag. By the time that was discovered metal had been cut on early production aircraft and the only bits that could be altered in time were the wing apex, leading edges and the wing tip. There is a production joint just where the 'kink' appears so it did not affect build difficulty all that much. similarly the detachable leading edges were easy to alter.
There really isn't any significant maintenance on the LE apart from de-icing mats ahead of the intake and they are all inboard of the kink
