Are these cracks developing as a result of excessive spanwise bending caused by leading and lagging of the blades?
First, I'm also in agreement with Lu on the latest Safety notice received concerning blade cracking. goes along with telling us that we shouldn't stick our D-cks into electric sockets eh?
However referencing the question posed, possibly. Certainly a contributor.
But I think the other inspection requirement was more for cracks at the root that they determined to be from high flapping and coning due to flights over gross weight, etc. didn't it?
