A. Prior to the accumulation of 1,200 flight hours or within 60 days after the effective date of this AD, whichever occurs later, and thereafter at intervals not to exceed 1,200 flight hours, inspect the engine power control cables for broken wires, in accordance with Shorts Service Bulletin SD360-76-08, dated May 9, 1988, or Revision 1, dated October 12, 1988.
