Lets forget about the idea of using TP5 and TP6 to retain the tailplanes on
to the torque tube. The problem with redesigning this is that its nigh on
impossible to retro fit and many Europa owners simply dont have the
expertise for such critical work.
Ivans idea behind the original tailplane attachent was to produce an easy
and quick way of rigging the aircraft. Regrettably time has proved this
design to be inadequate in terms of secuity.
There are several soultions proposed here which would require little if any
invasive work to the tailplane structure (my pin/ bolt through the back of
TP12 for example).
It might even be possible to build a small compartment behind the inboard
rib/ plywood insert and pass a threaded bolt through the rib into the
faceplate of TP12 (with a nut bonded to the back). Or a Zeuss ??? fastener.
This would bolt the tailplane securely to the TP12 drive plates. Its an idea
only and im not sure how feasible it would be.
