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.

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 . “Better bite the bullet” 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.

Hi All



Attached a photo about Dirk´s method in use. Operated well at least here in

Finland.



There was a plastic tube connected to the vacuum cleaner. It was a thight

fit to the plane. It forced the Loctite (because of vacuum) to come through

outwards. Process was completed when some visible Loctite was in the tube.

Without suction method - I do not believe Loctite will penetrate as well

only by itself.



***

Whole apparatus look like those things which are for sale behind the

windows of porn shops in Amsterdam. Some people think that the tube is a

nice way to lenghten personal tools if necessary. This is of course nothing

to do with Dirk - but maybe he got that great idea that way - doing some

window shopping
