\n```\n\n| Background: | This Directive requires a one-time inspection for discrepancies of all wire bundles, including certain power feeder cables, of the electrical system in the forward cargo compartment ceiling at certain stations and, if necessary, corrective actions. This action is necessary to prevent damage to wire bundles, particularly those of the fuel quantity indication system (FQIS), which are located in the subject area. Damage of FQIS wires could cause arcing between those wires and power wires in the damaged wire bundle and may lead to transmission of electrical energy into the fuel tank, which would result in a potential source of ignition in the fuel tank. |\n| ----------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |\n\n![](image.001.png) \nJames Coyne \nDelegate of the Civil Aviation Safety Authority\n\n13 December 2004\n\nThe above AD is notified in the Commonwealth of Australia Gazette on 26 January 2005.","sortOrder":0},{"sectionNumber":"AD/B767/204","sectionType":"part","heading":"AD/B767/204","content":"## AD/B767/204","sortOrder":1},{"sectionNumber":"Forward Cargo Compartment Wire Bundles","sectionType":"part","heading":"Forward Cargo Compartment Wire Bundles","content":"## Forward Cargo Compartment Wire Bundles","sortOrder":2},{"sectionNumber":"2/2005","sectionType":"part","heading":"2/2005","content":"## 2/2005","sortOrder":3},{"sectionNumber":"If the clearance between the:-","sectionType":"division","heading":"If the clearance between the:-","content":"### If the clearance between the:-","sortOrder":4},{"sectionNumber":"Is:-","sectionType":"division","heading":"Is:-","content":"### Is:-","sortOrder":5},{"sectionNumber":"Then:-","sectionType":"subdivision","heading":"Then:-","content":"#### Then:-","sortOrder":6}],"analysis":{"kimi_summary":{"content_quality":"ok","complexity_score":4,"scope_assessment":{"changed":false,"description":"This AD maintains focused scope on its original safety purpose — preventing wire damage in the forward cargo compartment of Boeing 767 aircraft.

(This is Requirement 1.)\n\n- Requires repair of any discrepancies found during that inspection in accordance with the ASB. (Requirement 2.)\n\n- Requires an examination of the clearance between those wire bundles (including the power feeder cables) and the cargo liner standoffs, and then carrying out specific corrective work depending on the measured clearance. (Requirements 3 and 4.)\n\n- Allows previously completed inspections and corrective actions done in accordance with earlier revisions of the same Boeing ASB (dated 11 May 2000, Revision 1 or Revision 2) to satisfy this Directive provided they covered the same wiring scope and locations.\n\n**Who must comply / who pays**\n\n- Aircraft owners and operators of the applicable Boeing 767 aeroplanes must have the inspection and any required repairs or installations carried out. The operator (or the operator's maintenance provider) bears the cost of inspection labour, any replacement parts (sleeving, lacing tape, cable spacers, straps or equivalent tie cord), and aircraft downtime while work is completed.\n\n**Where and when the work must be done**\n\n- The inspection applies to wire bundles in the forward cargo compartment from fuselage stations 368 through 742 and right buttock lines (RBL) 40 through 70, routed along the ceiling (as listed in the ASB).\n\n- Timing: the detailed inspection (Requirement 1) must be done within 18 months or 6,000 flight hours after the Directive’s effective date, whichever is later. Repairs found in Requirement 1 must be done before further flight (Requirement 2). The clearance examination is to be done at the same time as Requirement 1, with any corrective actions completed before further flight (Requirement 3 and 4).\n\n**Exactly what corrective actions are required depending on measured clearance**\n\n- For general wire bundles vs standoffs:\n - 6.35 mm (0.25 in) or more: no further action.\n - Between 3.3 mm (0.13 in) and 6.35 mm: install sleeving and lacing tape.\n - Less than 3.3 mm: install sleeving, lacing tape, cable spacers, and straps.\n\n- For power feeder cables vs standoffs:\n - 3.3 mm (0.13 in) or more: no further action.\n - Less than 3.3 mm: install sleeving, lacing tape and straps.\n\n- The Directive permits use of a tie cord P/N BMS 13-54 (or equivalent) as an alternative to the specified tie strap P/N BACS38K2.\n\n**Why the work is required (stated safety rationale)**\n\n- The Directive states that damage to wire bundles in this area — notably wires of the fuel quantity indication system (FQIS) — could allow arcing between damaged FQIS wires and adjacent power wires, with a risk of electrical energy being transmitted into the fuel tank and providing a potential ignition source. The inspection and corrective actions are intended to prevent such damage. (Background and Notes; the AD also refers to the related FAA AD 2004-22-25.)\n\n**How the Directive is implemented in practice (who decides and how)**\n\n- Maintenance personnel perform the \"detailed inspection\" (the Directive defines that term: an intensive visual exam with good lighting, mirrors, magnification and possibly surface cleaning or access work). The repairs and installations must follow the Accomplishment Instructions of Boeing ASB 767-24A0128, Revision 3 (the ASB supplies the procedural detail). The regulator (Civil Aviation Safety Authority delegate) enforces compliance with the Directive.\n\n**Costs, incentives and implementation trade-offs**\n\n- Direct costs: inspection labour, possible part purchase (sleeving, lacing, spacers, straps or tie cord equivalents), and aircraft downtime while the work is done.\n\n- Concentrated benefits: operators with affected aeroplanes reduce a specific electrical/ignition risk; maintenance facilities and parts suppliers gain one-off business.\n\n- Diffuse costs: fleet owners bear the expense (one-time per aircraft), and scheduling inspections to meet the deadline may cause aircraft to be temporarily removed from service.\n\n- Implementation risk and practical issues: accessing wiring routed along the cargo ceiling may require disassembly/cleaning or special lighting; interpreting marginal clearances (near the numeric thresholds) requires careful measurement; parts lead times may affect the time to return to service. The ASB cross-references and permissible part-equivalents limit discretion but require technicians to follow specific procedures in the ASB.\n\n**Concrete behavioural change required**\n\n- Operators must inspect the specified wiring, repair any damage before further flight, and alter wire routing/protection (sleeving, lacing, spacers, straps or approved equivalents) where clearances are below the thresholds. Maintenance providers must follow the ASB instructions for how to carry out these actions and document compliance.\n\n(See Requirement 1–4, Notes 1–2, and the compliance rows for timing and acceptable prior compliance in the Directive.)"},"flash_summary_failed":{"failed":true,"reason":"A positive credit balance is required for all requests, including BYOK, so fallback providers remain available.
