| Subject: | Re: Flap hinge FL9 bearing fit |
Chris,
Chapter 9, Fig 27 shows the FL9 bushing is installed with loctite. We didnt paint
the aluminum parts, so no reaming was necessary. Its been 15 years, so we could
be wrong, but it seems like it was a snug, but not press, fit.
Chapter 9, Fig 18 shows that FL19 and FL20 are mounted inboard of W18 and FL1 or
FL2 but the sketch Fig 27 implies they are outboard of W18. We had completed
the install of FL1 & FL2 in the flap prior to mating to the wing. To get proper
alignment of the flap to the wing, our FL19 (inboard) is mounted inboard
of W18 and FL1 is mounted outboard of FL19 and in the center, FL20 (center) is
mounted outboard of W18 and FL2 is mounted inboard of FL20. Not aesthetically
pleasing, but it works.
We didnt find it necessary to trim flap tube FL15.
Be sure to also note that W18 for the outboard flap hinge and outrigger has three
holes in it, not two like the inboards ones (see Chapter 9, Fig 12). This is
apparently often missed.
We incorporated Europa Club Mod 10661, Outrigger Pivot Bearing, during the build
and it has worked well.
Hope this helps.
Jim & Heather

Thanks for the reply Jim (or Heather :) ).
I measured the FL9 bushings and they are all around .374" (undersize). My plates
where powder coated at one point in the kit's life and it was quite hard to
remove from holes. I debated getting an undersized reamer ($$$) but not really
knowing which size to make the hole I just resorted to using a very fine small
sanding drum in the dremel and a light touch to remove the coat from the hole.
Worked well ok but would rather use a reamer. The fit of the bushings is good
but some are slight press and some slide in. Hopefully loctite will do its
job and, if problems arise in the future, it is always easy to repair these parts
(machining oversize bushings).
Regarding flap hinges, will take what you describe of your flap install and check
mine. I can make it fit perfect because I haven't installed any plates in the
flaps yet. I can adjust the depth of the tip and root rebates and make things
fit just right. Again, the concern is that if I displace the flap outboard
a little to make things fit properly then the flap torque tube could end up being
a little short. It's just me not knowing exactly how things fit at that stage
of the build. Just thinking ahead. I will go to the hangar now and try to
determine if the length of the flap control tube will allow a little fiddling
of the flap position. It really should as I think some tolerance in the build
should be allowed.
Again thanks for the feedback and pressing on! Hoping to have the wings finished
by early months of next year at which point I will have a mostly complete structure.
Then the 10:90 rule will apply and I will still have 90% of the build
time ahead of me :)
Chris Martin

I use and like the EZ HEAT on the 912S and the 914. Starts much easier with preheated
oil and crankcase..
