For airplanes that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must use the authority provided in paragraph (c) of this AD to request approval from the FAA. This approval may address either no action, if the current configuration eliminates the unsafe condition; or different actions necessary to address the unsafe condition described in this AD. Such a request should include an assessment of the effect of the changed configuration on the unsafe condition addressed by this AD. In no case does the presence of any modification, alteration, or repair remove any airplane from the applicability of this AD. \n\n\tCompliance: Required as indicated, unless accomplished previously. \n\n\tTo prevent smoke and fire in the avionics compartment due to electrical arcing that results from chafing damage to wires, accomplish the following: \n\n\t(a)\tWithin 30 days after the effective date of this AD, perform a visual inspection of the wire bundle in the avionics compartment for improper clamping and/or damage of the wiring, in accordance with McDonnell Douglas Alert Service Bulletin MD11-24A094, dated October 12, 1995. \n\n\t\t(1)\tIf the wire bundle is properly clamped and no damage is detected, no further action is required by this AD. \n\n\t\t(2)\tIf the wire bundle is improperly clamped, prior to further flight, reposition the wire in the clamp in accordance with the alert service bulletin. \n\n\t\t(3)\tIf any wiring is damaged, prior to further flight, accomplish either paragraph (a)(3)(i), or (a)(3)(ii) of this AD, as applicable: \n\n\t\t\t(i)\tFor wires (Loop A and B) having damage to any one fire detector controller (engines 1, 2, 3, and APU): Prior to further flight, splice one loop and replace the wire for the other loop in accordance with the alert service bulletin. \n\n\t\t\t(ii)\tFor wiring having damage other than that identified in paragraph (a)(3)(i) of this AD: Prior to further flight, repair the wiring in accordance with the alert service bulletin. \n\n\t(b)\tWithin 15 days after accomplishing the visual inspection required by paragraph (a) of this AD, submit a report of the inspection results (both positive and negative findings) to the Manager, Los Angeles Aircraft Certification Office (ACO), 3960 Paramount Boulevard, Lakewood, California 90712; telephone (310) 627-5200; fax (310) 627-5210.

Operators shall submit their requests through an appropriate FAA Principal Maintenance Inspector, who may add comments and then send it to the Manager, Los Angeles ACO. \n\n\tNOTE 2: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Los Angeles ACO. \n\n\t(d)\tSpecial flight permits may be issued in accordance with sections 21.197 and 21.199 of the Federal Aviation Regulations (14 CFR 21.197 and 21.199) to operate the airplane to a location where the requirements of this AD can be accomplished. \n\n\t(e)\tThe actions shall be done in accordance with McDonnell Douglas Alert Service Bulletin MD11-24A094, dated October 12, 1995.
