    Default Rudder pedal reinforcement KF-5?

    Hi,
    I see many threads about the rudder pedal reinforcement for the KF-4.
    Was there ever a SB for this issue on the KF-5?
    My kit was supplied in May of 1994 and it does not have the gusset's welded on in the corners from the horizontal torque tube to the vertical pedal tube. I see the the S7 manual on line at Kitfox shows these gusset' s. Are these gusset reinforcements required for my KF-5? Attached is a picture of my tubes.

    Joe,

    Yup - you want to do that. There have been some that have snapped off. Fortunately a friend of mine had a pilot in the other seat when one of his pedals broke.

    Can someone post up a pic with the gussets? I'm at the perfect spot to deal with this now

    A friend just had this happen on his model 5 while on short final. Got his Kitfox stopped with no damage. He has a flying buddy with a model 5 and had the same thing happen to his rudder pedal recently.

    Anyone has a picture of a reinforced pedal with gusset?

    I just went and looked at my pedal assemblies and they do not have the gussets. Then I looked in the KF7 manual and they are shown in most of the diagrams. Lousy picture shown here.

    I looked in the service bulletin section of my KF5 manual but there is nothing on this issue. If anyone has a copy of the SB, or at least the recommended change (sheet metal thickness, size, etc) it would be greatly appreciated. It's going to a a little tricky dancing around the rivets that are already installed.

    Alex, All the service bulletins are on the Kitfox website. Click on the home button and go to the technical facts button. They are listed for all Kitfoxes.

    Thanks... I am currently stripping a model IV, for a rebuild project. Maybe something I should consider...

    When I built my Series 5 '99 thru '03 the problems had not yet been occurring . When the Service bulletin came out I didn't want to pull the rudder pedal torque tubes to weld gussets so I used another method that allowed me to accomplish a fix with the pedals staying in place. I will get to the hangar tomorrow for some pictures and an explanation. Coming up on 1000 hrs with no problems. Bruce N199CL

    That's a gold mine, thank you. I'm seeing SB38 which only indicates Vixens, and I'm not finding a different one.

    Thankfully the fix does not include welding. That reinforcement looks straightforward enough.
