Hi Europa Builders from the deep cold  south,

  

 In regard to the recent tragic events and the PFA  Airworthiness Information that eventuated from it, I decided to go ahead with a  quick fix to the Tailplane pip-pin recess.

 I am one of those 'non compliance' builders with  regard to the recess, using, like many others I think, a circular plastic  plumbers end fitting with a screw top end. See photo. Sent to me by a UK builder back in 1997!!!

 This circular recess entered the tailplane touching  TP 6 Sleeve with a screw top lid. I found, to my horror, that the position of  the pip-pin head could just about move the distance of the TP12 bushes if  the TP 6  outboard sleeve became loose. I did not have any bid over the TP  6 Sleeve as per the manual. It was necessary therefore to have a backup and not  allow the head of the pip-pin to move at all restraining the tailplane from  moving outwards.

  

 I cut 2 x 16mm diameter aluminium tube to fit over  the pip-pin head and glued those into position to the TP6 sleeve.  I  established those positions by wrapping insulating tape around the pip-pin  head to increase their diameter to fit snugly into the tube and  installing the pip-pin in the TP6 sleeve. I put grease on the  insulating tape to stop gluing the pip-pin to the tube just in case. I then  filled the surrounding area within the circular plastic fitting with epoxy plus  flox up to the level of the aluminium tube holding the pip-pin.

 On one of the tailplanes I had to use a PVC tube(  increasing the diameter slightly by using black insulating tape, greased the  tape,) and placed it in the TP4 hole to form a circular floor (boundary) up  against the TP4 ceiling where the floor broke through the blue foam to  stop flox running into the TP 4 cavity.

  

 See photos to make better sense. I had another  Europa builder visit today to check it out.He liked it.  The tailplanes can  now only move 1/2mm before the head comes up against the aluminium tube sides as  a good backup.

  

 Email me if you think you may do likewise and need  some help.

  

 Cheers,

  

 Tim

Is it really cold in Christchurch? Cold in UK right now! I reckon all 

the 747 vapour trails are reflecting heat out and helping to cool the 

planet!



I admit to trying to guess what Andy is thinking but my understanding is 

that the object of the proposed exercise is to prevent the pip pin from 

pulling through the tailplane structure and uncoupling the drive pins. 

This is just a back up in case of failure of the TP6 bush bonding.



I was puzzled by the insistence on a "Minimum" area of BID lay up fore 

and aft. However this will be more difficult to pull through the foam 

core ( and the skin) than the cylindrical structure many of us have 

built. The PFA amendment also insists on a flox corner with the skin, no 

doubt for the same reason.

Open to correction?

Any comment Nev?

Graham

Tim,

  

 I had planned to make something similar

 but your plan & realization  is much much  

 more sophisticated.

  

 ***

 Can somebody there out see anything wrong in it  ?!?!

 If I did my tailplanes again, I should fit also one  long

 internal sleeve instead of two short ones.  Rigging

 would be not so irritating event...

  

 Thank you, Raimo

Graham,

When I was reading how the holes must be drilled through the TP6 and TP4 for 

the pip pins on the bench with a friend looking at 90° for correct position, 

I knew that it was practically impossible to ream the burrs at the 

underside. At the same time drilling first through SS TP6 with a cobalt 

drill means that you need directly to apply a certain force to have grip 

otherwise the drill would slide. This would result in all but perfect 

straight pip pins in all but perfect holes. So, before laying up the cloth 

on the tailplanes my holes were drilled and reamed. The recesses of 3 x bid 

were made and floxed to the rib, the TP6 and the foam. Even small pipes were 

glued at the underside to drain eventual captured water before the final lay 

ups. Didn't you have the impression of bad amaturisme when executing 

following the manuel?

Best regards,

yes I do. the engineering could have been done better. We have to 

remember though, Ivan was under a lot of pressure to get the whole 

design finished and sell some kits to start earning some money. Paying 

wages for three years with nothing coming in is quite scary. I have 

learned to accept Ivan for his strengths and forgive his shortcomings, 

without people like Ivan things like the Europa don't happen.I know I 

could not have done what he did, the Europa has given a lot of people a 

lot of pleasure. The rest of us can help each other to refine it and 

make it even more rewarding

And I add my

 very  few have drive and ability to do what  Ivan Shaw has accomplished!

There's a piece by Ivan in August's edition of Flyer, describing a  

recent trip in a Liberty around the Middle East and then across  

Europe to the UK.  Although entirely lacking in vanity, his piece  

shows he is something of a legend.



Its just a real shame he and Europa didn't stick together long enough  

to push through the sort of continuous refinement that, say, the RV  

range has had. What he did do however was so good that owners and  

builders have been able to pick up where he left off.

It's always been a mystery to me how the company evolved from the 

vision and accomplishments of Ivan into the chicanery of Keith Wilson. 

Some historical perspective from someone who has some knowledge on the 

subject, including the spin-off of the XS from the XL would be much 

appreciated.

Graham,

I completely agree with your opinion and I highly estimate Ivan for the 

dream he gave to me. I hope to show you my Rolls Royce Europa some day. 

Perhaps in Popham next week-end? When the weather .....
