    Default Another broken rudder pedal spring

    Had my third rudder pedal return spring break on me all within less than a year. This time it was the original spring on the left pedal. First two were right pedal. 170TT FX3. Broke while doing a forward slip on final.

    I know there are a number of threads on this and I did see a post from 5 years ago with a home made solution. Iíll call CC Monday to get a few more springs but has anyone heard of a solution from CC?

    Yup, I'm on at least two now, right pedal though. 188 hrs on the hobbs.

    I generally take the spring to the local hardware store and match one up.

    So far I have not seen an workable solution.

    Perhaps a naÔve question but why would you want to replicate a spring that fails? Either the spring specification was wrong or the spring did not meet specification.

    I have less spring tension than standard on my FX-3 as I extended the rudder cables to maximum length to give myself more front seat leg room. The springs don't really do anything while the pilot's feet are on the pedals.

    Andy,
    I canít speak for others, but in my case each replacement spring came from CC. At this point Iím thinking itís a design issue with the way the spring mounts to the frame mount point.

    as you observed the spring doesnít do much, but it is rather unnerving to hear it ďsnapĒ on final while in a forward slip...

    Same happened to me on CC SS and yo a friend on his FX-2. Must be a design issue.
