Posted: Sat Feb 26, 2011 8:51 am Post subject: tp9/tp10 retention

I am just about to fettle up the tailplane torque tube holes and bond the bearings into the fuselage, but I thought I remembered that there was some talk a while back of an improved TP9/TP10 retention mod, maybe even a factory approved scheme (as opposed to Bob Harrison's and Phil Tunney's clamps, and the factory Loctite approach). Am I dreaming or can anyone point me in the right direction?

My adaption of Bob Harrison's torque tube clamp has now been approved by the LAA as a standard Mod (11906).



The Mod is currently fitted to 1 flying aircraft, 1 ready for test flight and two others in the build stage.



Europa have now re-designed the torque tube.

Rowland,

I have a set of Bob Harrison's torque tube clamps - not fitted yet, so I 

thought I 'd weigh them for you: about 300g each.

I think it's worth it but you may - reasonably I suppose - think 

differently.

 I have had a set of Bob Harrison's torque tube clamp's fitted for three years and 300 hours and there isn't any movement

 in the pins and i know i can easily remove the tube for maintenance if necessary,

 I am very glad that they are more or less a fit and forget feature,

 just my two penny's worth!

Rowland,



        Pat Tunny's clamps are the way to go for my build. I did not need to drill the white nylon bush, as it may take a few attempts and in doing so you run the risk of making the TT holes bigger and this is where the unwanted movement is started. With Pat's clamps you set up the whole thing in one go, that includes the brass bushes too. then your dun. NO DRILLING. Easy and solid.

I had a message direct from Michel Auvray commending the glue method, but saying DON'T use Loctite 603. I will ask him why not, and what type he proposes instead.



In reviewing SB15 I don't seem to be able to find a copy of "PFA FSB- 006 issue 4" that specifies the inspection intervals. I though it would be in the Engineering part of the LAA website but I can't locate it.



Thanks again for your help.

Pat - thanks for the info, and apologies for calling you Phil before - I was confusing you with another PT.

I've not heard about this - how does the new design differ? As I've not bonded mine in yet, I might consider buying the new design. I have incorporated Factory Mod 62 (3/8" pins TP14) but would definitely consider a better engineering approach.

Hi Rowland,



With regards to the new re-designed torque tube then I have one of these.  As Roger put it to me, the new torque tube no longer has any torque.



Basically the whole design has been beefed up and there are now only 2 pins involved, not 4, see attached photo.



My main concern when I received this was the weight increase.  My numbers are below:



Old Tube: 



TP4  -  1350g

2 x TP5 & TP6  -  270g

TP9  -  200g

2 x TP12  -  800g

Total  =  2.620kg or 5.776lb



New Tube:



TP4  -  1330g

2 x TP5 & TP6  -  330g

TP9  -  1250g

2 x TP12  -  1060g

Total  =  3.970kg or 8.752lb  -  52% above original.



NB.  (Pat Tunney's clamps would add 0.4kg bringing an original assembly to 3.0kg).



My mind was originally put at rest when I was told that monos (or conventional taildraggers as my aircraft is likely to be) like having an aft c of g and so this additional weight at the back would be ok.  I tried not to think about it too much and decided it would be ok ......



Hope that helps.



Regards,



Phil

Wouldn't the same issue with hammering out of the holes (if not an interference fit) still apply to the two drive pins?



Just curious,

You could always put the battery in the original position under the cowling

on top of the foot well.  That would save you a great length of thick copper

cable.

Hi Phil

  

 I received a mono kit from Roger in late 2007 and I'm ashamed to say that I haven't touched the torque tube yet to know if it is the heavier version you describe - and I haven't seen a revised build manual or Mod 73 exemption that would take it into account - please can you tell me when did you get the new version from Roger, to give me a guide as to whether mine might be the new version with my kit?

   

 Thanks

 regards

 Richard

Hi,



In response to other postings:



The thickness of the material involved is greatly increased.  I guess the 2 pins may eventually wear the holes and introduce play but I think the rest of the aeroplane may have worn out long before.



Michel - picture attached with my posting.



Richard - I purchased my Torque tube early last year and I think the design had been around for a while before (at least 6 months).  If you could post a picture of your tube then I/the forum could easily identify what type it is.

Phil

Hi Phil,



Please excuse my lack of part number knowledge, but using descriptions instead:



- the center pushrod/counterweight driven assembly does indeed look thicker - and no longer stainless steel?

- the tailplane drive assemblies however look similar to the the original ones as far as material thickness is concerned... do they indeed have significantly thicker gauge tubes?

   

Cheers & thx,

Pete

Hi Peter,



You would have to check with the factory on this but:



1.  Centre section (originally TP9) is beefed up and on the grounds that it is zinc plated, it won't be stainless steel.

2.  The tailplane drive assemblies (TP12) are heavier according to my numbers and so yes, they are a thicker gauge.  Not sure how much thicker.



Regards,



Phil

Hi Richard,

  

 Although now retired I still follow the forum, so I  noticed your query.

  

 The new torque tube only came in shortly before I  retired at Xmas 2009, say mid 2009 from memory, so yours will definitely not be  the new heavier one.

  

 Best wishes for the build,

  

 Roger Bull
