Posted: Sun May 04, 2008 7:08 pm Post subject: Tailplane torque tube troubles

I installed the tail plane torque tube a couple of days ago and strayed it with AFS-50 then wiped it down with MEK.  I noticed that the plating is flaking off on one side.  I sent an E-mail to John asking him what he thinks I need to do.  

   

  Are there any ideals?  Have it replated, buy a new one?

Mine  (kit no 505) did the same in 2002.  I returned it to the factory who  arranged to have it re plated.  The second attempt worked  fine.

Rick

loose plating might give you trouble with tailplane removal, the fit in 

the tailplane bushes is quite tight.

Get it replaced or replated, that should not happen

My business is plating, including nickel plating.  When electrodeposited

nickel does not adhere to the substrate it is indicative of inadequate

cleaning and activation of the substrate.  DO NOT install any parts that

have the plated metal peeling because the problem will only get worse as

more material peels.

Thanks Rob, Yes, I know not to use it, but now what do I do.  ?Get a new part from England or have this one replated?  Still waiting for John to get back to me.

Hi! Rick  

My Europa G-PTAG had flaking nickel plate on the Torque tube from day one. Now 600 hours and no problems but you are advised to only use very light oil when fitting the tail planes. (Grease being very viscous tightens the assembly.)  

However it is therefore still possible, should water get ingressed that rust could eventually be a problem on long term fitted parts…….mine has been derigged almost every time it flies.  

Regards  

Bob H

Actually my point about not using it was to alert the others monitoring the list that no matter how slight a defect such as you have seen, not to use any part with plating that is peeling.  

   

I would not recommend re-plating.  Although it is possible to remove the nickel, for example by immersing the part in nitric acid, possible (likely?) damage to the substrate would make the part less than airworthy in my opinion.  The steel tube is so cheap that it would not be economical to spend the time to repair it – replacement is the likely answer you’ll get from the factory.

I am reading these torque tube troubles with a vested interest. I have a torque tube with some surface rust and my immediate view would be to replace the torque tube but for the fact of the job that it would entail.   

   

On a previous thread (a year or more ago) I read about the “earlier” torque tubes for the pre-XS Europas were not a standard dimension. Therefore the current torque tubes as supplied by the factory for the XS models will not be an exact fit for what I would like to replace. I believe I will have to work on the elevators as well as having the difficulty of extracting the torque tube itself.  

   

Has anyone experienced removing a torque tube in order to replace it and can offer some advice?  

   

At the moment my LAA inspector is reviewing what we have once I have cleaned up the torque tube after rubbing down wet with WD-40 with 800 grade sandpaper. If the tube looks too far gone after this exercise then I will not have any choice but to replace.

[quote]   --I had to replace a torque tube during a    rebuild. Could not believe that the nickel plating is hand removed to fit the    tailplane bushes and the assembly is then sold as a set as new. Fine until you    need a new torque tube when you find it wont go through the tailplane    bushings. 2 loose bearings in the tailplanes later after the cautious use of a    flapwheel on an extended drive shaft and I gave up on rebuilding any more    Europas.

    

   Hope that helps
