Moose flap main ribs
Posted: Sat Feb 18, 2012 10:02 am
Well I finally got off my butt and got out in the shop and tidied up. I got
the elevator back on the table to finish up only to notice that I had made a
mistake while working on it last. The two center ribs (EL-450) get cut down,
and the flanges are supposed to be bent to overlap in the middle, but I cut
them about an inch long, instead of the 4 inches or so they should have been.
Now I need to order 2 new ribs.
Anyway, I shelved the elevator again and started laying out the flaps. I've
got a question about trimming the main ribs. The MAM says mark and trim the
main flap ribs to 12 3/8 in. as show in figure 7.2.4. The figure shows the
rib pushed into the spar so that you are measuring from the face of the spar
to the tail end of the rib. I'm assuming that I cut the excess off the tail
end since there is a rivet flange on the spar end. The question I've got is
that the figure also shows a measurement from the face of the spar back 1
5/8". My guess would be that I'm supposed to trim the side flanges back to
this point so that they don't interfere with the spar flange, but there's no
mention of doing this, only the dimension shown in the figure.
