	Inspect forward rudder cable turnbuckles which attach to idler brackets located in lower fuselage truss aft of baggage compartment.  Turnbuckles should swivel freely.  Turnbuckle eyes with shank bent or filed down or which are otherwise damaged should be replaced.  Select an eye which swivels freely in idler bracket and use a clevis bolt of sufficient length to prevent binding. If shank of eye is bent, check alinement of rudder cable.
