The AD requires that the action set out in the requirement section (being action that the delegate considers necessary to correct the unsafe condition) be taken in relation to the aircraft or aeronautical product mentioned in the applicability section: (a) in the circumstances mentioned in the requirement section; and (b) in accordance with the instructions set out in the requirement section; and (c) at the time mentioned in the compliance section.\n\nAD/SD3-60/52\n\nAmdt 2\n\n  \nElevator Trim Control Cables 9/2000\n\nApplicability: All SD3-60 aircraft.\n\nRequirement: Action in accordance with Shorts Service Bulletin SD360 27-27 Revision 2\\.
