(b) If no discrepancy is detected, thereafter at intervals not to exceed 30 months, accomplish the "Maintenance Task" specified in paragraph 2.C. of Airbus Industrie Service Bulletin A300-29-097, Revision 2, dated August 27, 1991 (for Model A300 series airplanes); A310-29-2030, Revision 2, dated August 27, 1991 (for Model A310 series airplanes); or A300-29-6022, Revision 2, dated August 27, 1991 (for Model A300-600 series airplanes); as applicable.

(c) If any discrepancy is detected (e.g., the load to move the handle during operation of the left or right control cable is higher than 5.5 daN), accomplish paragraphs (c)(1) and (c)(2) of this AD: (1) Prior to further flight, accomplish the "Maintenance Task" specified in paragraph 2.C. of Airbus Industrie Service Bulletin A300-29-097, Revision 2, dated August 27, 1991 (for Model A300 series airplanes); A310-29-2030, Revision 2, dated August 27, 1991 (for Model A310 series airplanes); or A300-29-6022, Revision 2, dated August 27, 1991 (for Model A300-600 series airplanes), as applicable. (2) At intervals not to exceed 30 months after the accomplishment of the Maintenance Task in accordance with paragraph (c)(1) of this AD, repeat the Maintenance Task in accordance with the applicable Airbus Industrie service bulletin.
