On all model 8KCAB aircraft, revise the FAA Approved Airplane Flight Manual to delete Sections 1.2.1 through 1.2.7. Insert the following after Section 1.2 Acrobatic Category Limitations: All acrobatic flight, including intentional spins, is prohibited. B) Effective immediately, all affected aircraft with 100 hours or more cumulative flying time and every 100 hours thereafter must have all flight control cables inspected for evidence of wear, fraying, or stretching. If such wear, fraying, or stretching, is found, replace the defective flight control cable before further flight, except that the airplane may be flown in accordance with FAR 21.197 to a base where the repair can be made. C) All flight control cables of the affected aircraft must be replaced in accordance with Bellanca Aircraft Corporation Service Letter No. 104, dated September 12, 1972, and subsequent revisions or in accordance with data approved by the Chief, Engineering and Manufacturing Branch, Great Lakes Region. On those airplanes with less than a cumulative flying time of 600 hours, replace cables before reaching 700 hours. On those airplanes with a cumulative flying time of 600 hours or more, replace cables within the next 100 hours flying time. Cable replacement on all affected aircraft must be accomplished by January 1, 1973. All replaced cables must be rendered unusable for any further aircraft applications or handled in accordance with Bellanca Aircraft Corporation (Champion) Service Letter No. 104, dated September 12, 1972, and subsequent revisions. Any cables replaced in compliance with Airworthiness Directive 72-18-03 are exempt from this airworthiness directive. D) The placard required by paragraph "A" may be removed; the revision to the Airplane Flight Manual required by paragraph "A" may be deleted; and the repetitive inspections required by paragraph "B" may be discontinued when compliance with paragraph "C" of this airworthiness directive is accomplished. This amendment becomes effective October 5, 1972. FOOTER:
