I have been working on improving a number of minor issues on N 41726, including root fairings, Aeromatic prop, landing gear retraction and fit and general sealing. After the installation of the Aeromatic I became concerned about slop in the Aileron control loop. I had noticed that one of the ailerons was flying higher than the trailing edge of the wing. I fixed the left one centered on the wing and was able to moved the right control surface 3 to 4 inches without any resistance. This strikes me as way to much free play in the system. There are 8 connection in the loop from the left control horn to the right, each one has some play between the bolts and the bushing. Has anyone address this issue with a high time Cadet? If so what was the solution? Does anyone have knowledge of a Cadet experiencing flutter of the ailerons? I am planning to replace all the fitting in the system but would like to know what is acceptable as far as the maximum amount of free play. Tim

Tim,
That seems like way too much slop. I just rigged my ailerons, can't say for sure, but don think there is 1/4" total. I wonder about your bushings. Missing one or two would make a big difference. Also maybe they are just worn, or the bolts. Try replacing both at a hinge point one at a time and I bet you will find the culprit. Also check the jam nut on the push rod going to the aileron. That much slop makes me nervous...Keith

Thanks Keith, I agree way too much movement. I removed the entire aileron push rod system including bellcranks. All joints had bushing with a little play. Constructed new push rods using rod ends. I will post picture soon. I have not had time to install them yet but will l let everyone know how it turns out. Tim
