51-10-02 LUSCOMBE: Applies to All Model 8 Series Aircraft.
Compliance required by the next periodic inspection, but not later than June 1, 1951, and at each annual recertification thereafter.
Due to recurring failures of the control cables, all cables should be carefully inspected at each section which passes either over a pulley or through a fairlead. To properly inspect the cables, they should be removed from the airplane to the extent necessary to expose the sections to be inspected. Care should be taken that the method of inspection is not damaging to the cable; i.e., do not sharply bend any strand or the whole cable and do not "bird-cage" the cable to the extent of putting permanent set in the strands or the whole cable. Any unairworthy cables must be replaced.
In reinstalling the control cables, the rigging of the entire control system should be checked and properly adjusted. The control surface travels may be obtained from Aircraft Specification A-694. Care should be taken that none of the cables drag across or rub against any structure or equipment due to misalignment of the fairleads. Luscombe Airplane Corp. Service Bulletin No. 1-51 furnishes further information on this subject and Luscombe Airplane Corp., Garland, Texas, should be contacted for further information, if needed, in rigging controls.
