The OP should know that the SB says that cracks that do not reach
the spar flange radius can be stopdrilled and monitored. His mechanic
should take a close look at the SB again. The amount he flies, they
might go no farther.

I should have obtained a copy of the SB but I've been way too busy this
week to deal with this. Still haven't seen the cracks myself, but my
partner in the airplane is a professional photographer and he took some
pictures of them yesterday. I should have them soon.

From my IA's description, the cracks radiate from the edge of the
lightening hole about 1" each. Not sure if they reach the flange
radius. I'll call him and ask.

Thanks for the info.
