Ben,

Thank you. The ones by the strut attach point are the
only ones I figured I needed and was wondering if any
others were possibly needed for future use. I have
gotten the one lug nut plates from Wayne some time ago
so I will be using them for the aileron hinges and
will not be putting in the inspection holes for that
area. Thanks again.

inspect holes at the aileron hinge points, but I

don't do these because they instead use nutplates
for the hinge bolts, and

hinge points I left out the hole on the root or end
(left or right wing)
where the hinge nuts are outside. Making the holes
and getting the
doublers just right is a bit time consuming and to
some extent might not be
too bad adding after the plane has been flying.

I think I may have asked this question before but
for
some darn reason I can not access the rebel-list.

I am finally back in Hawaii and trying to pick up
where I left off on the wing construction and I am
wondering if it is necesary to put inspection
covers
any where in the wings and where they would be
located.

Thank you,
Keith R661

MAM discouraged me from adding any more than those two holes. They
especially didn't want any near the wing root. The original manual was
accompanied by a bulletin with details of those two holes at the strut
attachment for anyone who wanted them. So far the only use I've found
for them was for spraying in corrosion-x and for wiring and plumbing my
pitot tube. In my case I also added an access hole for changing and
aligning my landing lights simply because it is awkward to remove a
wingtip when working alone.

Ken,

Are you trying to say that the ones by the strut are
unneccesary also? I would think they would be needed
for inspection during annual time.

Ahhh you caught that subtlety Keith ;)
Yup I remember the wording on the bulletin as making it sound optional.
No one has ever mentioned those bolts needing attention to my knowledge
so I would think they are optional. I have no idea whether a inspector
for a second purchaser in the USA might insist on looking in there
though. Certainly they would look if the holes are there and I suspect
they'd advise you to put them if you ask but... I doubt that I'll look
in there on my annual unless it is to spray in more corrosion-X.

Ken,

I'd be interested in more info about your pitot installation, especially
photos, if available.

Hi Ron

I uploaded a small grainy pic to Rebel Misc.
I changed from MAM's pitot on leading edge to a used heated cessna tube
when I added the Mackenze STOL cuff. I am quite pleased with how it
works and I've never banged into it as it is well protected by the wing
strut. It is mounted on an access plate, as close to the wing spar as I
could get it, and a piece of streamline aluminum tubing locates it about
5 inches below the wing. Since I have a bad habit of flying in poor
weather, I thought that a heated tube might be nice but it is much
easier than I expected to land a Rebel without an airspeed indicator.
For IFR flying after a horizon failure, a functioning ASI is nice but
that is also highly unlikely.

FWIW,
I extended my fuel tanks into the 4th bay. This puts the outboard solid tank
rib close to the strut attach inspection hole. It is nice to be able to see
that end of the tank through the hole. I also have my tank vent's coming
through that end of the tank, so I can inspect the fittings there as well,
and hopefully replace the vent line if it gets bent.

I guess the Rebel is different than the Super Rebel. Inspection holes were
already there in my lower wing skins. A bit of trivia. I marveled at how
long it was taking me to install all my inspection plates in the wings,
fuselage, etc., so I decided to count up how many screws I would have to
remove and replace every year for the annual condition inspection. My jaw
dropped when I realized it was way over 400! Thank goodness I got a
cordless screwdriver for Christmas!
