## Summary

We propose to adopt a new airworthiness directive (AD) for certain Viking Air Limited Model CL-215-6B11 (CL-215T Variant) and CL- 215-6B11 (CL-415 Variant) airplanes. This proposed AD was prompted by a report that a supplier fabricated Teflon parts with a charge of 15 percent fiberglass content instead of the specified 5 percent fiberglass content. This proposed AD would require repetitive detailed visual inspections of the aileron control system cables and flap interconnect system cables for damage or disconnected cables, corrective actions if necessary, and replacement of the Teflon parts in the aileron control systems, aileron/rudder interconnect, and aileron power unit beam. The replacement of these parts would terminate the repetitive inspections. We are proposing this AD to address the unsafe condition on these products.
