The wings pulled, you can see and feel most of the
center section. the lighting holes are big enough to reach in there
.
The important things to check for are of course the
spars - main and rear.
And here is a slight problem. One can only see the
insides of the spars . The main spar side facing to the front is covered by
the tanks and the rear side spar facing to the tail is hard to see, cause of
very small holes to see through. see : https://home.pacbell.net/hbeil/ercoupe/corrosion.htm
Corrosion seems to happen more likely here, so a
check with a boroscope is a good idea. It does not have to be the one described
in the AD, I guess, since pulling the wings is already sufficient to fulfill the
AD's requirement.
Inspections holes are a good idea in the rear part
of the center section, no doubt. But to thoroughly check the front of the main
spar, one would have to remove the tanks also.

Or can a good job be done without it? With a wings pull, does that meet a once every three year inspection requirement?
