Airworthiness Directives; American Champion Aircraft Corporation Models 7AC, 7ACA, S7AC, 7BCM, 7CCM, S7CCM, 7DC, S7DC, 7EC, S7EC, 7ECA, 7FC, 7GC, 7GCA, 7GCAA, 7GCB, 7GCBA, 7GCBC, 7HC, 7JC, 7KC, 7KCAB, 8KCAB, and 8GCBC Airplanes

The FAA is adopting a new airworthiness directive (AD) for certain American Champion Aircraft Corporation (ACAC) Models 7AC, 7ACA, S7AC, 7BCM, 7CCM, S7CCM, 7DC, S7DC, 7EC, S7EC, 7ECA, 7FC, 7GC, 7GCA, 7GCAA, 7GCB, 7GCBA, 7GCBC, 7HC, 7JC, 7KC, 7KCAB, 8KCAB, and 8GCBC airplanes. This AD requires you to make a temporary Pilot's Operating Handbook (POH) limitation entry or install a temporary placard prohibiting aerobatic flight if you operate the airplane before the required inspection of this AD; inspect for incorrect swaging width of the cable Nicopress sleeves on the elevator, rudder, aileron, and flap control cables; replace cables that have incorrect sleeve swage width; remove POH limitation or placard prohibiting aerobatic flight after inspection and replacement of cables with incorrect sleeve swage width; and report any findings of incorrect sleeve swage width to FAA. This AD results from partial loss of aileron control because an incorrectly swaged cable sleeve allowed the cable to slip. We are issuing this AD to detect and correct incorrect swaging widths of the flight control cable Nicopress sleeves, which could result in failure of the elevator, rudder, aileron, and flap controls. This failure could lead to loss of control of the airplane.
