AD/B767/210 - In-Flight Entertainment System Cooling

The instrument is organised around a small number of concrete technical and procedural concepts. These are: model applicability, part‑level replacement, reference to manufacturer's service bulletins and the aeroplane maintenance manual, a prohibition on installation of an identified spare part number, explicit compliance timeframes, and cross‑reference to the equivalent FAA action.

Applicability. The AD applies only to Boeing 767 series aeroplanes listed in the two Boeing Service Bulletins specified, namely Boeing Special Attention Service Bulletin 767‑21‑0188 for Model 767‑300 and 767‑21‑0189 for Model 767‑400ER, both dated 27 May 2004. The AD therefore targets a defined fleet subset and does not purport to apply to other 767 variants or models not listed in those service bulletins.

Part replacement. The central corrective measure is hardware replacement at the part number level: remove P/N 285T1198‑101 and install P/N 285T1198‑102 in the P50 card file in the main equipment centre. The AD identifies the exact component, its location on the aeroplane, and the replacement part number.

Method of compliance. Compliance must be performed "in accordance with the Accomplishment Instructions" of the specified Boeing service bulletin for the applicable model. Where the service bulletin permits an "operator's equivalent procedure", that procedure is constrained by the AD to one that follows the procedures in the chapter/subject of the Boeing 767 Aeroplane Maintenance Manual specified in the service bulletins. This links manufacturer instructions and the AMM as the authorised methods of work.

Prohibition on spare usage. The AD contains an immediate prohibition (effective date) against installing the older part P/N 285T1198‑101 "as a replacement spare", regardless of whether it is already in operator stock.

Compliance timelines and effective date. Requirement 1 has an 18‑month compliance window measured from the AD's effective date, which the document sets as 9 June 2005. Requirement 2 is effective immediately as of the AD effective date.

Cross‑reference to foreign authority and history. The AD notes FAA AD 2005‑07‑13 as a related document. The service bulletins are dated 27 May 2004; the AD is dated 27 April 2005 and became effective 9 June 2005. The AD includes a one‑paragraph background statement explaining the safety concern: possible incorrect interpretation of signals by the IFE cooling system which, during a forward cargo fire, could allow the IFE cooling fan to cause smoke penetration into occupied areas.

Combined, these concepts create a compliance rule that ties specific hardware replacement to manufacturer instructions, imposes an immediate spare‑part ban, and allows a constrained operator equivalence route via the AMM.

The directive's obligations fall on operators and maintainers of the Boeing 767‑300 and 767‑400ER aeroplanes that are identified in the two Boeing Special Attention Service Bulletins (767‑21‑0188 and 767‑21‑0189, both dated 27 May 2004). The document's language and the compliance mechanics identify the following affected parties and their roles.

Registered operators and aircraft owners. The people responsible for ensuring that an aeroplane complies with an AD are the operator or owner who control the aeroplane and its maintenance regime. The AD targets aircraft that contain the P50 card file in the main equipment centre with an installed IFE cooling card P/N 285T1198‑101. For those aircraft, the operator must schedule and ensure replacement with P/N 285T1198‑102 within 18 months of 9 June 2005.

Maintenance organisations and licensed engineers. The technical act is a replacement of a card in the main equipment centre. The AD requires the work be done "in accordance with the Accomplishment Instructions" of the Boeing service bulletins, or if using an "operator's equivalent procedure", done according to the procedures in the chapter/subject of the applicable Boeing 767 Aeroplane Maintenance Manual specified in the service bulletins. That prescribes the controlling procedural documents and identifies maintenance organisations and licensed engineers as the parties who execute and record compliance.

Supply chain and parts providers. The prohibition in Requirement 2 ("IFE cooling card, P/N 285T1198‑101, may not be installed on any aeroplane as a replacement spare") affects parts inventories and spare‑parts suppliers. Suppliers holding P/N 285T1198‑101 stocks will face an immediate restriction on that part being fitted as a replacement spare as of the AD effective date. Operators will need to obtain P/N 285T1198‑102 to comply with Requirement 1, creating demand for the improved card.

Regulators and delegated officials. The AD is issued by the Civil Aviation Safety Authority, signed by James Coyne as Delegate of CASA. That identifies CASA as the regulatory decision maker issuing the prescriptive requirement and the delegate as the signatory. The AD also cross‑references FAA AD 2005‑07‑13, indicating a regulatory alignment with FAA findings and measures.

Passengers and cabin crew as indirect stakeholders. While not addressees of the AD, the stated safety rationale concerns the potential for smoke to penetrate occupied areas during a forward cargo fire if the IFE cooling system misconfigures. Therefore passengers and crew are beneficiaries of the mandated mitigation.

Who does not appear to be affected. The AD does not apply to other Boeing 767 variants not identified in the service bulletins. It does not order changes to other IFE components beyond the cooling card, or require software or procedural changes beyond those in the Boeing service bulletins and AMM.

The text in the AD therefore assigns duties principally to operators and maintenance organisations who control the aeroplane and its parts inventory, and it imposes immediate constraints on spare parts availability and future maintenance choices.

The AD establishes a small set of explicit duties and one clear prohibition. The document does not set out discretionary rights for operators beyond the constrained "operator's equivalent procedure" route. What follows is a practical statement of the obligations as worded in the AD, without inferring additional rights or enforcement mechanisms not present in the text.

Primary duties.

• Replace specified part. Operators of affected airplanes must replace the IFE cooling card P/N 285T1198‑101 with the improved P/N 285T1198‑102 in the P50 card file in the main equipment centre. The AD requires the replacement "in accordance with the Accomplishment Instructions of Boeing Special Attention Service Bulletin 767‑21‑0188 (for Boeing Model 767‑300 series aeroplanes) or 767‑21‑0189 (for Boeing Model 767‑400ER series aeroplanes); as applicable." This ties the method and sequence of work to the manufacturer's specified Accomplishment Instructions.

• Observe the replacement timeframe. Requirement 1 must be completed "within 18 months after the effective date of this Directive." The stated effective date is 9 June 2005. That establishes a concrete compliance interval for scheduling and performance of the replacement.

• Follow the AMM where using operator equivalent procedure. If the service bulletin(s) permit an "operator's equivalent procedure," the AD constrains that alternative to procedures "in the chapter/subject of the applicable Boeing 767 Aeroplane Maintenance Manual specified in the service bulletins." That means the operator may use an alternative method only if it aligns with the AMM chapter/subject the service bulletin indicates.

Prohibition.

• Do not install the old part as a replacement spare. Requirement 2 states: "IFE cooling card, P/N 285T1198‑101, may not be installed on any aeroplane as a replacement spare." The AD makes that prohibition effective "as of the effective date of this Directive." There is thus an immediate restriction on the use of the older card from 9 June 2005 forward.

Implicit administrative duties (as present in the AD text). The AD requires use of specified Boeing service bulletins and the Boeing 767 Aeroplane Maintenance Manual where operator equivalence is relied upon. These are procedural constraints that direct which technical documentation must be used to effect the replacement.

Rights or options stated in the AD.

• Operator's alternative route limited by AMM. The AD permits, but limits, the option to use "operator's equivalent procedure" where the service bulletin allows it. The AD does not otherwise grant a general right to deviate from the Accomplishment Instructions. Any such operator equivalent must conform to the AMM chapter/subject specified in the service bulletin.

• Applicability check. The AD implicitly requires operators to check dollies, records and the Boeing service bulletins to confirm whether a specific aeroplane is listed. The AD's "Applicability" clause identifies which aeroplanes are in scope and so provides operators a means to determine whether they are bound by the Directive.

What the AD does not state. The text does not enumerate penalties, enforcement processes, or consequences for non‑compliance beyond the compliance deadlines and prohibitions already described. It does not specify who pays for parts or labour. It does not specify how to treat existing installed units other than to require replacement subject to the timeframe, nor does it provide transitional exemptions or deferred compliance options other than the explicitly stated 18‑month window for Requirement 1.

The AD text supplies explicit compliance actions and timeframes, but it does not set out fines, criminal sanctions, or administrative penalty procedures within the document itself. The Directive specifies what must be done and by when, yet it does not, in the provided text, describe the consequences or enforcement mechanics for failure to comply.

What the AD does state about enforcement‑relevant facts. It sets discrete compliance deadlines: Requirement 1 must be completed within 18 months of the effective date (effective date 9 June 2005) and Requirement 2 is effective immediately as of that date. It also names the referenced Boeing service bulletins and the Aeroplane Maintenance Manual chapters/subjects to be used for the method of compliance. Those elements are enforcement‑relevant because they set objective performance standards: the relevant part numbers (P/N 285T1198‑101 and P/N 285T1198‑102), the installation location (P50 card file in the main equipment centre), the documents that define proper accomplishment, and the timetable.

What the AD text does not specify. The document does not identify particular regulatory penalties, administrative sanction procedures, or civil remedies to be applied in the event of non‑compliance. It does not specify inspection regimes, audit schedules, reporting obligations to CASA beyond the replacement requirement, or whether evidence of compliance must be lodged with CASA. The AD does not detail corrective action processes where an operator cannot source the new part within the compliance window. It also does not set out processes for seeking exemptions, extensions, or approvals for alternative means of compliance other than the limited "operator's equivalent procedure" route tied to the Boeing 767 Aeroplane Maintenance Manual.

Practical enforcement implications derived from the AD’s content. The AD creates objective, document‑based compliance criteria that allow a regulator or an inspector to assess whether an aeroplane has or has not complied: is the aircraft one of the models listed; has the part P/N 285T1198‑102 been installed in the P50 card file; are maintenance records consistent with the Accomplishment Instructions or AMM chapter/subject if operator equivalence was used; has any P/N 285T1198‑101 been fitted as a replacement spare since the effective date. Those are the discrete facts that would determine compliance when assessed.

Reference to related foreign action. The AD notes "FAA AD 2005‑07‑13 Amdt 39‑14037 refers." That indicates concurrent FAA attention and provides a reference point for inspectors or compliance teams seeking to compare regulatory actions internationally. The AD itself, in the provided text, contains no enforcement policy beyond the compliance mandates.

Where to find enforcement detail. The AD does not include enforcement procedural detail. For those specifics , whether administrative enforcement, civil or criminal penalties, or the processes for seeking relief , the operator should consult CASA's enforcement policy, guidance materials and any accompanying notices or directive registries. The AD’s text, however, sets out the objective replacement and spare‑use prohibition that would be the basis for any enforcement action.

The AD explicitly cross‑references and integrates manufacturer documentation and a related FAA directive. The interconnections in the text are limited to specific documents and procedural dependencies; the AD does not purport to displace or rewrite other laws. The interactions in the AD are documentary and operational, not legislative cross‑amendments.

Reference to Boeing service bulletins and the Aeroplane Maintenance Manual. The AD requires replacement "in accordance with the Accomplishment Instructions of Boeing Special Attention Service Bulletin 767‑21‑0188" or 767‑21‑0189, "as applicable." It also stipulates that where the service bulletins permit an "operator's equivalent procedure," the replacement must be done "according to the procedures in the chapter/subject of the applicable Boeing 767 Aeroplane Maintenance Manual specified in the service bulletins." This binds the AD’s compliance method to manufacturer's service documentation and the established AMM chapters specified therein. It therefore creates an operational interaction: compliance is measured against the manufacturer’s technical instructions.

Reference to FAA AD. The AD includes a note stating "FAA AD 2005‑07‑13 Amdt 39‑14037 refers." That documents regulatory alignment with the United States Federal Aviation Administration's action on the same technical issue. The AD’s background also specifically cites that the FAA received a report prompting concern. This suggests that CASA’s AD is implemented in the context of an international safety finding and that operators may need to review both the CASA AD and the FAA AD for full technical and compliance context.

No textual conflict with other laws in the AD text itself. The AD does not identify any inconsistency with statutory obligations, nor does it purport to amend or derogate other legal instruments. The AD is a prescriptive safety instrument referencing technical documents. It is an operational regulatory instrument; integrating manufacturer instructions does not require rewriting other regulatory texts.

Document hierarchy and compliance testing. Practically, the AD places the Boeing service bulletin Accomplishment Instructions and the specific AMM chapters/subjects as the operative technical standards for compliance. Thus, where regulators or auditors evaluate compliance with the AD, they will compare work against those documents. The AD’s prohibition on installing P/N 285T1198‑101 as a replacement spare operates concurrently with any other regulations governing parts control, maintenance recordkeeping and airworthiness.

Limitations on operator modifications. The AD allows an "operator's equivalent procedure" only to the extent the service bulletin states that such an approach is permissible and then only if it follows the AMM chapter/subject specified. The AD therefore contains an operational constraint on departures from Boeing’s Accomplishment Instructions, tying any allowable deviation to the AMM procedures.

No mention of ancillary statutory processes. The AD does not set out how it interacts with statutory regimes such as licensing, airworthiness certification renewal, or penalties under broader aviation safety legislation in the provided text. For those interactions, an operator or legal adviser must consult CASA’s broader regulatory framework and guidance materials.

The document provided contains minimal amendment history information. The text itself records dates relevant to the AD’s issuance and the associated manufacturer service bulletins, but it does not show later amendments, revocations or supersessions. The recorded dates and milestones in the AD are:

• Boeing Special Attention Service Bulletins 767‑21‑0188 and 767‑21‑0189 are both dated 27 May 2004. These service bulletins are the technical documents that the AD requires operators to follow for the replacement work.

• The AD is dated 27 April 2005 and signed by James Coyne, Delegate of the Civil Aviation Safety Authority. That is the date of signature in the text.

• The AD states an effective date: "This Airworthiness Directive becomes effective on 9 June 2005." Requirement 1 requires replacement "within 18 months after the effective date of this Directive." Requirement 2 is effective "as of the effective date of this Directive."

• The AD also includes a Note that "FAA AD 2005‑07‑13 Amdt 39‑14037 refers," indicating that the FAA published a related AD in 2005. The AD does not record the FAA AD's date in the text beyond that reference.

No subsequent amendment entries present. There is no text in the provided document indicating that the AD was later amended, extended, superseded, withdrawn, or modified. The document does not include an "Amendment" field, an "AS AMENDED" notation, or later effective dates.

No transitional or grandfathering provisions. The AD includes only two requirements and their effective times; it contains no further transitional arrangements or staged amendment history within the document.

If a reader requires a full amendment history beyond the dates and references recorded here, the AD as supplied does not provide it. To obtain an authoritative amendment and status history, readers should consult CASA’s official AD registry or database, which records whether an AD has subsequently been varied, superseded, or withdrawn. The text provided does not perform that function and contains only the original issuance details and the cross‑reference to the FAA AD.

The provided AD text does not reference any litigation, judicial decisions, appeals, or complaints arising from this Directive. It names only administrative references: Boeing Special Attention Service Bulletins 767‑21‑0188 and 767‑21‑0189, FAA AD 2005‑07‑13, the effective date, and the issuing delegate James Coyne. There are no case citations, court judgments, tribunal decisions, or administrative appeals recorded in the AD itself.

Absence of litigation references. The AD’s background and content focus strictly on the technical safety concern, the required corrective measure and operational constraints. The document does not include any notes relating to legal challenges, stays, injunctions or judicial interpretation. It also does not provide procedural guidance for appeals or for seeking alternative means of compliance beyond the limited operator equivalence permitted under the service bulletins and AMM.

How to proceed if litigation or disputes are a concern. Given the AD contains prescriptive obligations and compliance timeframes but no litigation history, a party seeking to know whether any legal proceedings have intervened would need to look outside the AD text. That would include searching CASA enforcement records, tribunal decisions, or court databases for any challenges, or querying CASA for any recorded appeals or enforcement actions related to AD/B767/210. The AD document itself offers no litigation track record.

No judicial interpretation or precedent provided. There are no judicial statements that interpret the AD’s scope, applicability or procedural requirements within the AD text. Any operator or legal adviser needing to know how courts have treated the obligations or evidential standard for compliance must source those materials externally, as the AD does not supply them.

This section highlights practical pitfalls and attention points grounded in the AD text. Each point refers back to explicit language in the Directive so that teams can avoid common errors when implementing the AD.

Part number precision. The AD names two part numbers: the old card P/N 285T1198‑101 and the replacement P/N 285T1198‑102. The Directive’s requirement is strictly tied to those P/Ns. A common operational error would be to fit a part with a similar, but different, P/N or to misread a P/N on inventory labels. The AD’s prohibition on installing P/N 285T1198‑101 "as a replacement spare" is absolute as of the effective date. Ensure inventory systems, spares catalogues and procurement orders match the exact P/Ns in the AD.

Scope and applicability checking. The AD applies to Boeing 767 series aeroplanes "listed in the following Boeing Service Bulletins" and then identifies the two service bulletins by number and date. Operators must confirm whether a specific aeroplane is among those listed in the service bulletins. Do not assume all 767‑300 or 767‑400ER aircraft are automatically in scope; check the service bulletin applicability lists.

Location on the aircraft. The AD specifies the location as "the P50 card file in the main equipment centre." Maintenance teams must be certain they remove and replace the correct card in the correct physical location. Errors in identifying the card file may lead to incomplete compliance.

Operator's equivalent procedure constraints. The service bulletins may state that replacement can be done using an "operator's equivalent procedure." The AD does not allow an unconstrained operator procedure; it requires that any operator equivalent be "according to the procedures in the chapter/subject of the applicable Boeing 767 Aeroplane Maintenance Manual specified in the service bulletins." Do not assume an in‑house preferred procedure will satisfy the AD unless it is recorded that the service bulletin allows operator equivalence and it follows the AMM chapter/subject specified.

Timing mismatch risk. Requirement 1 must be completed "within 18 months after the effective date of this Directive," with an effective date of 9 June 2005. Some operators might plan replacement only at the next heavy maintenance check and thereby risk exceeding the 18‑month window if that check date is later. Plan scheduling early enough to meet the AD timeframe.

Immediate spare‑part prohibition. Requirement 2 prohibits installation of P/N 285T1198‑101 "as a replacement spare" as of the effective date. That means any attempt to use existing P/N 285T1198‑101 spares for unplanned rectification after 9 June 2005 would conflict with the AD. Operators must quarantine or otherwise flag any P/N 285T1198‑101 items in stock to prevent inadvertent re‑installation.

Documentation and records. The AD requires method‑based compliance through Boeing service bulletin Accomplishment Instructions or specified AMM chapters. Maintenance logs and airworthiness records should therefore record the specific service bulletin used and whether the AMM chapter/subject was followed where operator equivalence was used. Failing to document the precise method may make it difficult to evidence compliance.

Supply chain and lead times. Although the AD does not specify supply arrangements, the requirement to replace the old card with the new part implies that operators must source P/N 285T1198‑102 units. Operators should be aware of potential lead times and avoid relying on installation of prohibited spares.

Interplay with FAA AD. The AD notes that "FAA AD 2005‑07‑13 Amdt 39‑14037 refers." If operators are internationally flagged, they should check whether the FAA AD includes different or additional requirements or guidance; the CASA AD establishes the Australian requirement but cross‑references FAA material which may be useful for technical detail.

Misreading the safety rationale. The background links the technical defect to possible events during a forward cargo fire, noting the risk that "the IFE cooling fan causing smoke to penetrate occupied areas of the aeroplane." Do not substitute alternative safety assumptions. The AD prescribes the part change to mitigate the specific failure mode described.

No penalties or enforcement detail in the text. The AD sets the performance standard but does not list enforcement procedures or penalties. Operators should not assume the absence of stated penalties means non‑compliance has no consequence; compliance teams should contact CASA for enforcement guidance if needed.

Compliance requires a set of concrete, documented steps that follow the AD’s wording: confirm applicability, schedule and perform the replacement per Boeing Accomplishment Instructions or approved AMM chapter, ensure the prohibited spare is not installed, and maintain records that demonstrate compliance within the required timeframe. The AD itself defines the permitted methods and the compliance deadlines.

Step 1 , Confirm applicability. Obtain Boeing Special Attention Service Bulletin 767‑21‑0188 (dated 27 May 2004) if operating Model 767‑300 series aeroplanes, and 767‑21‑0189 (dated 27 May 2004) if operating Model 767‑400ER series aeroplanes, and check the applicability sections in those documents to confirm whether each specific aeroplane is listed. The AD makes applicability contingent on the aircraft being "listed in the following Boeing Service Bulletins."

Step 2 , Inventory and parts control. Identify any installed IFE cooling card P/N 285T1198‑101 in the P50 card file in the main equipment centre. Flag and segregate any stock of P/N 285T1198‑101 so as to prevent inadvertent installation as a replacement spare after the AD’s effective date. Order sufficient quantities of P/N 285T1198‑102 to cover replacements; lead times may affect scheduling.

Step 3 , Plan maintenance window. Schedule the replacement within the AD’s timeframe: "within 18 months after the effective date of this Directive." With an effective date of 9 June 2005, the replacement must be completed within 18 months of that date. Integrate the task into a maintenance plan to ensure completion before the deadline.

Step 4 , Follow the authorised method. Carry out the physical replacement "in accordance with the Accomplishment Instructions of Boeing Special Attention Service Bulletin 767‑21‑0188 or 767‑21‑0189; as applicable." If the service bulletin indicates that an "operator's equivalent procedure" is permissible, ensure that any such operator procedure follows the procedures in the chapter/subject of the applicable Boeing 767 Aeroplane Maintenance Manual specified in the service bulletins. Document which document was followed for the method of compliance.

Step 5 , Execute and test. Remove P/N 285T1198‑101 from the P50 card file and install P/N 285T1198‑102 per the Accomplishment Instructions or the relevant AMM chapter. Perform any post‑installation checks, functional tests or system verifications described in the service bulletin or AMM. Ensure that the IFE cooling system configures correctly and that system interfaces behave as specified by the Accomplishment Instructions or AMM procedures.

Step 6 , Records and certification. Record the replacement in the aircraft maintenance records, including the serial numbers of parts installed and removed, the service bulletin number and revision used, the AMM chapter/subject if an operator equivalence was used, the date of completion and identity of the certifying licensed engineer or maintenance organisation. Since Requirement 2 prohibits installation of P/N 285T1198‑101 as a replacement spare as of the effective date, record any disposition of removed P/N 285T1198‑101 parts (for example, marking as unserviceable or return to vendor) to show they will not be reused.

Step 7 , Communicate within the organisation and to supply chain. Notify spare parts managers and procurement that P/N 285T1198‑101 is prohibited as a replacement spare from the AD effective date and that procurement should acquire P/N 285T1198‑102 for future requirements. Ensure maintenance planners are aware of the compliance timeframe so that scheduled maintenance includes the replacement.

Step 8 , Cross‑reference FAA and Boeing materials. Consult FAA AD 2005‑07‑13 (Amdt 39‑14037) as the AD notes that it "refers." The FAA AD may provide related technical detail, and Boeing service bulletins contain the Accomplishment Instructions and any notes about operator equivalent procedures. Ensure that the exact service bulletin revision used is the one specified in the AD and that the AMM chapter/subject referenced is followed where applicable.

Step 9 , Seek clarification from CASA if needed. The AD text does not detail enforcement, exemption or extension procedures. If an operator cannot source P/N 285T1198‑102 within the timeframe, or wishes to use an alternative compliance method beyond the operator equivalence described, contact CASA to seek formal direction or approval rather than assuming a course of action.

Step 10 , Maintain audit trail for compliance verification. Keep maintenance records and part disposition records available for any inspections or audits. The AD’s compliance obligations are document‑tied; clear evidence that the Accomplishment Instructions or the specified AMM procedures were followed will be central to demonstrating compliance.

Following these steps aligns operational planning and execution with the AD’s explicit commands: replace P/N 285T1198‑101 with P/N 285T1198‑102 per the identified Boeing service bulletins or via AMM‑based operator equivalent procedure, complete the work within 18 months of the effective date, and ensure the older card is not installed as a replacement spare from the effective date.
