Joe Norris recently purchased N7733, a very nice W8 built by Wally Carlberg in 1963. A previous owner had made a local flight and was turning around in front of his hangar. During the turn one rudder pedal broke off. The airplane was in IL and I was in CA. I gave him detailed instructions on how to cut the pedals out. He shipped them to me and I made removeable pedals as described above. Shipped them back to him and they fit perfectly. I think that was around 2007 and they are still in the airplane two owners later.?

Another more recent incident, an instructor was flying a Tailwind from the right seat and the rudder pedal broke on takeoff and the airplane made a long excursion off the runway.?

This is very valuable information.

We had an off-runway excursion due to rudder pedal to tube failure, no tabs before; all tabbed after.

Only the very early W8's were a two shaft system. Early W8's used round tubing for the rudder pedals, later changed to square tubing. Arms that the cables attach to were same as pedals round then square.

As much as I hate adding weight I don't want to lose the airplane because of a broken rudder pedal. I increased the wall thickness of the outer tube to .049 and the square tubes to .049.

I highly recommend making the rudder pedal assembly removeable. This is done by adding a .058 wall bushing to the bottom of the pilots right pedal. Drill and ream thru the bushing and the 3/4" tube for a tight fit on AN3 bolt. Machine a solid aluminum plug about 3/4" long? to fit inside the 3/4 tube. Drill a 1/4" hole thru the bushing. Epoxy the bushing inside the 3/4 tube with the hole in the bushing in line with the hole for the rudder pedal in the 3/4 tube. The intermediate bushing has tabs that bolt to some tabs on fuselage diagonal. AN3 bolts To remove the rudder pedals remove the bolts in the intermediate bushing and the bolt at the bottom of the rudder pedal. Telescope the pedals inward until the pedal assembly can be removed from the longeron bushings.?

I strap only the aft side of the pilot side pedals at the intersection of the torque tubes. The strap on the cable arms go on the forward side.?

Which drawings are you looking for? W-8 was a 2 shaft system and the W-10 is a single shaft system?
