HELLO.

 I strongly suggest that before anyone call the NDT technician out to perform this inspection, you or your A&P should do it first.  A certain amount of rework is allowed on the spar cap should corrosion or a crack be found.  By inspecting first, you can repair the spar, within the limits described in the SB, then call out the NDT Tech.  If the NDT inspector finds the crack first, he will send paper work to both the FAA and the factory and you airplane will forever be branded as an airplane with a cracked spar.  Not the best thing for resale value.  I recently delivered a 680 Commander that had exactly that issue.  The airplane is now required to have the spar inspected each 100 hours and had a ream of paperwork in the permanent records.  Like a good lawyer, "never ask a question you don't already know the answer to".  jbGet the Moviefone Toolbar. Showtimes, theaters, movie news, & more!

Just out of curiosity, does the FAA or the factory have information 

which supports the 100 hour inspection?  ie: is there a significantly 

higher occurance of spar cracking or failure on a spar which has had an 

existing crack ground out?
