In Annex E it says:
Check that trim bellcrank does not contact TS05 push-rod when fully aft (ta
b full up) and tailplane is=0A
trailing edge up.
This should be in Chapter 19 also but is not as it is assumed when checking
clearances.
If I read you correctly=2C I am just repeating what others have said I am a
fraid. With the stab full up and trim rod full down=2C the TS05=2C T shape
d trim push rod=2C should not contact the TS 03 bell crank long arm side wh
ere the trim clevises attach at full up stab (I use 13 degrees full up). T
he clevis from the motor to the clevis on the TS03 butt against one another
on the #8 rod attaching them. If you look with the stabs all done=2C trim
tabs on=2C and fully extended trim motor=2C look hard at the TS05 trim rod
and it normally just contacts the clevis. Simply take it apart=2C(it is a
n airplane so if you haven't taken it apart and put it together 5 times=2C
you are doing it wrong.) cut 1/16 inch from each clevis and reassemble and
test. 1/8 inch off each is the most I have done. At this time check the T
S05 trim push rod does not rub against the slot in the bulkhead it passes t
hrough. This is very hard to do with the top on.
Nice to catch it now with the top off rather than go in and try to do it af
ter the top is on=2C especially with the inspection hole size recommended b
y the manual.
Now something not in the manual and is very embarrassing:
I found one of my aircraft with the nyloc nut which holds the TS03 to the T
S04 (spring and washer thingy) and its check nut were loose. As the damper
unit moves=2C it vibrated a bit and to my distress=2C the TS04 was a bit f
loppy. This has never happened to me. Easy fix=2C a drop of Loctite and t
ighten up was all it took. I use torque seal paint on all my bolts but nev
er put it on my nylock / check nut on the drag / dampener bolt as I never t
hought this part would cause trouble... So a word to the wise=2C make this
part of your final assembly check=2C and put a bit of torque seal paint on
your nuts on this part also.
As far as mounting the trim servo=2C we do add an aluminum plate of .016 in
ches with 4 nut plates riveted on to it and the plate Reduxed and riveted t
o the back side of the bulkhead. We use nut plates everywhere where we can
't get to a nut easily. (Yes=2C it takes longer but we have not had good l
uck with gluing a nut on over time.) We also use a #6 Allen head screw to h
old the trim motor on since it is easier to put an Allen screw driver ball
head on it than a wrench should the trim motor need to be changed some time
in the way distant future. (I've never had a Mac Servo fail=2C but I hav
e a D sub on it anyway=2C just in case.)
Enjoy Building

Hi Bud=2CCould you please elaborate where the fouling is more specifically?
I appreciate knowing this=2C so I am thankful Bob brought it up. I have th
e top still off so its ideal I overcome these issues now. Regards Tony Rens

You are right on the money. Every aircraft I have built needed about =0A
