installed and not damaged (e.g. chafed), installing a new grommet if not already installed or if the existing grommet is damaged, relocating the wire support standoff as applicable, installing protective sleeving over certain wire bundles, and installing wire bundle support clamps.  When installing wire bundle support clamps, make sure that wire bundles are installed inboard/above the insulation blankets.

                For Group 2 aeroplanes - the procedures in Work Package 2 include performing a detailed inspection of the sleeving on wire bundles W298, W235, and W2130, as applicable, to determine the type of protective sleeving installed and the location of that sleeving, relocating the sleeving or replacing the sleeving with new sleeving as applicable, and installing wire bundle support clamps as applicable.  When installing wire bundle support clamps, make sure that wire bundles are installed inboard/above the insulation blankets.

                For Group 1 aeroplanes, actions accomplished before 11 December 2001, per Boeing Alert Service Bulletin 767-24A0134 (for Model 767-200 and -300 series aeroplanes), dated 15 March 2001; or Boeing Alert Service Bulletin
                767-24A0135 (for Model 767-400ER series aeroplanes), dated 15 March 2001; as applicable, are acceptable for compliance with Requirement 3.

             Note 2:  FAA AD 2004-05-07 Amdt 39-13501 refers.
Compliance:  For Requirement 1 - Within 30 days after the effective date of this Directive.

             For Requirement 2 - Before further flight after the Requirement 1 inspection.

             For Requirement 3 - Within 18 months after the effective date of this Directive.
             This Amendment becomes effective on 22 October 2009.
Background:  This Directive is amended to remove reference to cancelled AD/B767/155 and FAA AD 2001-17-28 Amdt 39-12419 that have been superseded by this Directive and FAA AD 2004-05-07 Amdt 39-13501.  The actions specified by this Directive are intended to detect and prevent abrasion damage and correct installation discrepancies of the wire bundles located below the P37 panel, which could result in arcing to structure and consequent fire or loss of function of affected systems.

   This Directive requires inspections to determine whether the existing location of a certain wire support standoff is adequate, relocating the wire support standoff if necessary, installing protective sleeving over the wire bundles and installing wire bundle support clamps if necessary.  The Directive also expands the applicability of the existing Directive to include additional aeroplanes together with requiring inspection of the sleeving on certain wire bundles and accomplishing corrective action, if necessary, on those aeroplanes.
