Just a quick question... the plans mention cutting out a portion of the rear spar so the elevator control horn can rotate with the proper clearance. At what point should this be done? Also, I don't see any measurements or anything for how much to remove from the rear spar.
I'm just getting ready to prime these parts, then rivet. Should this be done now or later on when fitting to the fuse?
Thanks!
I got kind of stuck on this too when I was working on it, so here is what I did.
First, I checked VAF and found out just where on the plans the cutout on the Rear Spar (HS-603PP) is mentioned. If I recall, it is shown in the upper, left-hand corner of DWG 3 (but check for yourself before making any actual cuts).
Second, although the instructions specify making the cut after the stiffener is installed, instead what I did was to:
cleco everything up,
mark the area to be cut,
remove the clecos,
then make the cut, but make the cut just a tad less than indicated.
I expected that it would be much easier to make the cut before installing the stiffener as opposed to after installing the stiffener.
Third, after installing the stiffener, then I went back and filed out the cut just enough for the horn to function properly.
In retrospect, I think that making the cut before riveting the Rear Spar Reinforcement Bars was the best course.
I hope this helps!
