I was surprised to discover those cracks forcing me to replace the

Don't assume the cracks will be that large to be easily seen espcially
if you leave the bridge in. *I have seen a case where the dye check
was inconclusive, but the dye pen ran inside the tube right through
the edge of the weld! * This was only found when the part was on the
bench in bright light, with a magnifier as called for in the AD.
