Compliance is required as indicated.

To prevent possible rudder cable failure, accomplish the following:

(a) Within the next 10 hours' time in service after the effective date of this AD and thereafter at intervals not to exceed 100 hours' time in service from the last inspection, inspect the rudder cables for broken wires of any strand at the points the cables leave the top of the rudder pedals throughout the maximum to minimum rudder pedal adjustment range, and also immediately aft of the cable ferrules.

(b) If a broken wire of any strand is found during an inspection required by paragraph (a) of this AD, before further flight, replace the defective cable with a serviceable cable of the same specification or an FAA- approved equivalent cable and continue to comply with paragraph (a).

(c) The repetitive inspections required by this AD may be discontinued after a rudder pedal stop, P/N 59A-45-445, or an FAA approved equivalent is installed as follows:

(1) Remove the instrument panel.

(2) Remove the two screws (self tapping type) retaining the pedal assembly cover (channel section) and remove this cover.

(3) Position the stop to the upper guide tube and push it firmly up against the forward tube support; tighten the bolts.

(4) Replace the pedal assembly cover and instrument panel.

(5) Check controls for full and free operation.

NOTE: Vickers-Slingsby Technical Instruction No. 78, dated March 15, 1976, also covers the installation of the rudder pedal stop.
