Hi! Bruno,
I was unaware that the fatal accident involving William and Paul had
categorically been attributed to the tail plane issue?
Since I also believed that there was an issue concerning wing rear lift
pins
And close out lay ups with the aluminium strips being mis 'aligned so
the
threaded holes were broken through the side of the plates. I saw one
photo
into the root lay ups where there was serious separation in that the
layers
were glossy after separation.
Frankly.... the slop between tail plane trailing edges is likely to
cause
flutter of catastrophic proportions so I personally have little
confidence
in Loctite as a permanent solution. It is also conceivable that the slop
will result in constant battering of the stabilator inner bearing
bonding .
=93Better bite the bullet=94 and send an order for my clamps! See the
current
LAA mag, where it is alleged that the pins wear, this is incorrect
because
it is actually the torque tube which becomes slotted by the radial loads
---From the pins. (Not PIP PINS)
I am aware of a number of aircraft where the Loctite method has failed.
The issue of stabilator retention PIP PINS requiring the torque tube
matching holes radially elongating (ONLY the torque tube or your PIP
pins
may fall OUT) and the de-bonding of the inner stabilator bush allowing
the
stabilator to exit from the drive pins at the close out, are completely
separate and independent issues, but likewise are of vital importance.
To
loose the drive to one stabilator would have unthinkable consequences.

Subject: Europa-List: Mod 73 and Service Bulletin 15
Hi Family,
The accident with William and Paul happened not due to a technical
problem
with the Europa, it was a built problem.
But further investigations were showing that some builders had not made
the
layout of the pippin/tailplane correctly. Therefore to avoid problems
for
the future Mod 73 was issued.
As there was in addition a play via the complete system (from the stick
to
the tailplane due to the sum of connections) the Service Bulletin 15 was
issued.
Here it is mandatory to use Loctite 603 (very low viscosity) and apply
it to
all fixed connections. Dirk Oyen had for that a great solution (using a
vacuum cleaner to get the Loctite between the bushes and the torque
tube).
He made pictures and gave it at that time to the forum. Maybe it is
still
available.
I hope this helps.
Best Regards,
Bruno

Hi Brian.
To me it feels like play, i will check again, and slide the Stablators
off
and check inserts making sure they are bonded.
I am just a pilot but i could have done a better job in designing this
linkage.
As this has the possibility of grounding the aircraft for some
considerable
time, due to the fact that clamps are individually made to size, Why
has,t something not been done about it.??
Why can,t you get a complete unit with clamps already made, so the job
could
be done in one go, say a day, not grounded for 2 months.
Alan
