Not sure if anyone on the list is still in the wing build stage on their
Rebel... but if you are......I've been "inside" 7 wings since late
September
and every friggin one of them has the AN3 bolts "shouldered". These are the
bolts that attach the 1/4" thick spar caps to the main spar. One wing, out
of a pair, that I was in.. even had the spar backer bolted in this way the
FULL length of the wing !!.. not just the three bays around the attach
strut.
The overlength bolt/threads showing is an oversight on MAM's part in the
manual and in their AN960-10 washer supply... but every one of these bolts
needs an extra washer fellas so go buy a couple hundred now for $20. When
you can see 3+ threads showing on an AN3 bolt the nut is shouldered onto
the
grip of the bolt and it's not really tight..and possible that it's been
cracked from running out of thread.
The really sad part.. only two of these wings that I've inspected/worked on
are USA built that can have an "excuse" with no preclose inspections south
of our border.. but the Canadian ones.. should have been snagged before
they
got closed up this way!
That is all...
