AD 50-39-01

50-39-01 CESSNA: Applies to All Models 190 and 195 Aircraft, Up to and Including Serial Number 7586.

Inspection required not later than November 25, 1950, on aircraft having 300 hours or more service and at each 100 hours operation on all aircraft.

Service experience has indicated that close inspection of rudder cables is necessary in order to detect premature cable fraying at the forward pulley. Due to the difficulty of inspection and since some failures may have occurred in core strands, the following methods are recommended: Detach the rudder cable from the rudder bellcrank in the aft fuselage or at the rudder horn at the pedal and pull the cable through the inspection openings immediately aft of the rudder pedal or through the tunnel at the aircraft centerline in the cabin. The cable should then be carefully inspected, by flexing, at a point 9 to 10 inches aft of the swaged fitting at the forward end of the cable for broken strands. Replace all cables showing signsof breakage.

The above inspection may be discontinued when at least the next larger size pulleys are installed.

(Cessna Service Kit, SK 9050-1 provides the larger pulley and inspection opening for those aircraft prior to Serial No. 7587.)
