Anyone had experience of hairline cracks in the upper wing two inches forward of the trailing edge, through the NO STEP decal?

Seems to have occurred over a period of time since the spar gear support AD was installed eighteen months ago.

Seen a few posts hear where some damage has occurred on occasions and wonder if these have been as a result of the same problem.

Any advice welcomed.

Dom,

 

Assuming you are talking about a 320/360, are any pictures available? 

Are you sure no one stepped on the "No Step" decal? 

Do the cracks run parallel to the rear spar?

If parallel, how far from the spar (there is 2 bid 1 inch from the spar)?
