Docket 92-NM-188-AD. Supersedes AD 87-12-08, Amendment 39-5652. Applicability: Model BH/DH/HS/BAe 125 series airplanes; as listed in British Aerospace Alert Service Bulletin S.B. 24-A261, Revision 1, dated August 17, 1987; certificated in any category. Compliance: Required as indicated, unless accomplished previously. NOTE: Paragraphs (a) and (b) of this AD restate the requirements of AD 87-12-08, Amendment 39-5652, paragraphs (a) and (b). As allowed by the phrase, "unless accomplished previously," if the requirements of AD 87-12-08 have been accomplished previously, paragraph (a) of this AD does not require that the initial inspection be repeated. To prevent a circuit from overheating and a resultant fire, accomplish the following: (a) Within 10 days after July 7, 1987 (the effective date of AD 87-12-08, Amendment 39- 5652): Inspect the battery cables to detect chafing and local damage, in accordance with British Aerospace Telex Alert Service Bulletin S.B. 24-A261, dated March 6, 1987; or British Aerospace Alert Service Bulletin S.B. 24-A261, dated March 9, 1987, or Revision 1, dated August 17, 1987. If chafing or damage is found, prior to further flight, replace the affected cable, in accordance with the applicable service bulletin. (b) Repeat the inspection required by paragraph (a) of this AD at intervals not to exceed one year, and, if chafing or damage is found, replace the affected cable prior to further flight. (c) Modification of the wiring installation at Panel ZL (Modification No. 253204A or B), in accordance with British Aerospace Service Bulletin SB.24-261-3204A&B, Revision 1, dated March 24, 1988, constitutes terminating action for the repetitive inspections required by paragraph (b) of this AD. (d) An alternative method of compliance or adjustment of the compliance time that provides an acceptable level of safety may be used if approved by the Manager, Standardization Branch, ANM-113, FAA, Transport Airplane Directorate. Operators shall submit their requests through an appropriate FAA Principal Maintenance Inspector, who may add comments and then send it to the Manager, Standardization Branch, ANM-113. NOTE: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Standardization Branch, ANM-113. (e) Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate the airplane to a location where the requirements of this AD can be accomplished. (f) The modification shall be done in accordance with British Aerospace Service Bulletin SB.24-261-3204A&B, Revision 1, dated March 24, 1988. (NOTE: The issue date of this British Aerospace Service Bulletin SB.24-261-3204A&B is only indicated on "page 1 of 12"; no other page is dated.)
