That would be very unfortunate. It's pretty clear that SH has provided
suitable places to drill holes on the premise that whatever boroscope
used is fairly short. Clearly, the underlying objective is to make sure
that the entire length of the upper spar flange (aft side) is visually
inspected for any areas which didn't get enough resin and therefore
might not be adequately bonded. If you can do that with a 25-30' long
boroscope then you'd be complying with the intent of the tech note. If
you call around to some companies specializing in NDT or perhaps who do
boiler tube inspections, etc. you may find a suitable scope.

Changing the subject just a tad. It's obvious that if one can locate a
boroscope or similar device with a roughly 25 foot reach that it may be
possible to inspect the vast majority of the wing from a single well
placed hole. Those who have begun this process may be able to comment.


Not sure what the FAA would do but our New Zealand CAA would require an AMOC
to be completed and OK'd before the inspection could be changed from that of
the Techicnal Note or AD and a 25 ft long boroscope would not be lying
around most workshops. The Manufacturers has stated the inspection to be
carried out and that stands. The holes drilled can be taped up if they are
small enough . ( according to the TN note) Becomes academic if the web needs
repairing I guess.
