47-43-04 CESSNA: (Was Service Note 2 of AD-768-5.) Applies to 120 and 140 Aircraft Serial Numbers 8001 to 12349, Inclusive.
Inspection required upon each 100 hours of operation until horns are reinforced.
Remove the forward part of the tunnel fairing on the cockpit floor and inspect the control cable horns on the rudder bar for signs of bending which probably is caused by excessive foot pressure during application or release of the parking brakes and results in a reduction of the rudder travel. Bent parts which can be straightened without cracking should be reinforced by the installation of Cessna P/N 0411303 or its equivalent. Cracked parts should be replaced with Cessna P/N 0310168 made of 0.080-inch steel.
(Cessna Service Letter No. 43 dated July 7, 1947, covers this same subject.)
