The MCAI describes the unsafe condition as:
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Do the following actions.
(1) For airplanes subject to maintenance review board report (MRBR) requirements: Within 30 days after the effective date of this AD, revise the supplemental structural inspection (SSI) portion of the airplane inspection schedule, in accordance with paragraph 1.D.(2) of BAE Systems (Operations) Limited Inspection Service Bulletin ISB.53-175, Revision 1, dated April 2, 2007. Do the initial inspection at the applicable time, and repeat at the applicable intervals, as specified in Appendix 3 of BAE Systems (Operations) Limited Inspection Service Bulletin ISB.53-175, Revision 1, dated April 2, 2007. Where Appendix 3 of BAE Systems (Operations) Limited Inspection Service Bulletin ISB.53-175, Revision 1, dated April 2, 2007, does not specify a compliance time in either flight cycles or in flight hours, use flight cycles.

Do all applicable corrective actions before further flight, except that replacements of all the wing links that are not within the specified tolerance must be done before the airplane reaches its MRBR airframe life limit.
Note 1: For the purposes of this AD, a detailed inspection is: “An intensive examination of a specific item, installation, or assembly to detect damage, failure, or irregularity. Available lighting is normally supplemented with a direct source of good lighting at an intensity deemed appropriate. Inspection aids such as mirror, magnifying lenses, etc., may be necessary. Surface cleaning and elaborate procedures may be required.”
