Hello Alex,
My tailplane is the same. This is typical and does not affect the flying quality
or characteristics of the plane. If I recall correctly the lower fuselage
has a slight twist in it. I would suggest leaving as is.
If you attempt to relocate the bushings in an effort to level the torque tube you
will change the alignment of the tailplane with the mating profile molded into
the sides of the fuselage. This mismatch between the fuselage and tailplane
will be very noticeable. Hence, the recommendation to leave as is.
Regarding the modification to tailplane mass balance arm. Again, if I recall correctly
the TP18C Adjuster Body was adjusted to the extreme end of TP18B End
Fitting. This created a large bending moment at root end of TP18C resulting in
its failure. Europa issued mod 70 with a redesigned mass balance arm and constraint
of the TP19 Weights.
The failure was attributed to a number of landing mishaps. Regardless, the original
design did not adequately keep the weights from swinging side to side as
there was no means to tighten or adjust the lateral restraining cables. Additionally,
it was deemed that heavier tube and a stronger adjusting mechanism were
warranted.
Lastly, I noted that you have kit number 529. Most likely your kit has the redesigned
TP18 arm. Per the documentation in Mod 70, kits up to number 194 were
affected (those delivered prior to February 2005). So, maybe this isnt an
issue for you.

Thanks Eric for a detailed and comprehensive reply!
I have passed on the kit to a friend, who intends to complete it and I am trying
to get him started.
This kit was delivered in 2002 and has the cables as standard, so I believe it
is pr-mod 70 and so the arm will need replacing.
I do believe the slight misalignment will not result in any noticeable effect,
but that will be up to the new owner to decide- your recommendation is noted and
I do agree with you.
I am not sure if I understand what you mean by saying realigning the bush will
have a detrimental effect on, as it seems the bush will only move a tiny amount
and into the correct position..?
As the factory is no longer responding to requests, we will have to try to make
up parts for the required mods, (57, 70, 72, 73 and 74) so any info such as photos,
dimensions and material specs and other info not available in the modification
instructions, or help in obtaining the parts, would be immensely appreciated.

James,
You have no idea how that relieves me, I had just sold the kit when the new o

Having had my mind on other things for years, I have not followed up on info
