AD/B767/247 - In-Flight Entertainment Systems

The directive revolves around several distinct concepts drawn from aviation regulatory practice. An “Airworthiness Directive” is a legally enforceable notice issued by CASA requiring the inspection, modification, or change in operating conditions of an aircraft or aeronautical product to correct an unsafe condition. This AD is the Australian equivalent of the US FAA AD 2008-23-15, and it incorporates that FAA AD by reference for the purpose of accepting later service bulletin revisions approved as an AMOC. The “in-flight entertainment system” (IFE) refers to the audio, video and possibly other entertainment equipment installed in passenger cabins. The directive treats the IFE system as a “non-essential electrical system” because its loss does not affect the safe operation or continued safe flight and landing of the aeroplane. The “utility bus switch” is a cockpit control that energises or de-energises an electrical bus supplying certain loads; the modification connects the IFE power supply to a bus controlled by this switch so the flightcrew can cut power without having to locate individual circuit breakers. “Service bulletins” are optional manufacturer instructions that become mandatory when adopted by an AD. The directive names specific Boeing service bulletins, each with its own set of accomplishment instructions detailing parts, wire routing, relay types and testing procedures. The concept of “Alternate Method of Compliance” (AMOC) allows a regulator to approve a different means of achieving the same level of safety as the original AD. Here, the CASA directive accepts an FAA-approved AMOC to the corresponding FAA AD, provided the later service bulletin revision is approved by the FAA as an AMOC to FAA AD 2008-23-15. This creates a regulatory reliance on a foreign agency’s determination, which may simplify compliance if the FAA acts promptly but also introduces a dependency that could delay or confuse operators if the FAA approval takes time or is not precisely mirrored in CASA’s records. The background statement attributes the directive to an FAA review of IFE systems, and asserts that the flightcrew’s inability to turn off power to IFE systems and other non-essential electrical systems during a non-normal or emergency situation could result in an inability to control smoke or fumes in the flight deck or cabin. This is a purpose claim rather than a demonstrated fact, and the directive does not cite any specific incident, accident, or failure data.

This directive directly affects any person or organisation that holds an Australian airworthiness certificate or operates a Boeing 767-200, 767-300, or 767-400ER aeroplane on the Australian register, or that operates such an aeroplane under an Australian air operator certificate. The applicability statement does not limit the directive to Australian-registered aircraft only; it is a CASA instrument, so it binds anyone who operates an aircraft within Australia’s regulatory jurisdiction that meets the model description. The affected parties include scheduled and charter airlines, cargo operators, aircraft leasing companies that position 767s in Australia, and any maintenance organisation that performs the modification work. The compliance burden falls primarily on the operator, who must schedule the modification into heavy maintenance checks, procure parts, hire labour, document the work, and update the aircraft’s continuing airworthiness records. The directive also imposes duties on maintenance providers (such as CASA Part 145 approved organisations) because they must correctly follow the service bulletin accomplishment instructions. The original equipment manufacturer, Boeing, is indirectly affected because it may need to maintain the supply of modification kits and respond to technical queries about the service bulletins. Passengers and crew are the intended beneficiaries of the safety improvement, but they bear no direct compliance cost. CASA itself is affected in a supervisory role: it must monitor compliance, investigate breaches, and possibly issue exemptions or alternative means of compliance. The directive also has a secondary effect on aircraft trading: any 767 imported into Australia after the effective date would need to be already compliant or be modified promptly, which could affect the price and timing of aircraft transfers. Because the directive relies on later revisions of service bulletins being acceptable if approved by the FAA as an AMOC, it also affects the relationship between CASA and the FAA: Australian operators must be aware of US regulatory developments to know which bulletin revision is currently compliant.

The primary duty imposed by this directive is to perform the modifications described in the referenced service bulletins within the specified compliance times. For the wiring and relay installation (requirements 1.a., 2.a. and 3.a.), the operator must accomplish the work within 60 months after 15 January 2009, which means any affected aeroplane must be modified by 15 January 2014 at the latest. For the “all other actions” requirements (1.b., 2.b. and 3.b.), the operator must accomplish those actions before further flight after the wiring modification is done. This creates an operational constraint: once the wiring work begins, the aircraft cannot be returned to service until the remaining actions (which may include testing, inspections, or record amendments) are complete. The operator also has a duty to ensure that any later revision of the service bulletin that is used has been specifically approved by the FAA as an AMOC to FAA AD 2008-23-15. Reliance on an unapproved revision could result in non-compliance even if the modification is physically equivalent. The operator has the right to seek an alternative means of compliance from CASA directly, although the directive does not expressly mention that right; under the standard CASA regulatory framework, any AD can be subject to an application for an exemption or an alternative means of compliance. The directive does not grant any right to defer the modification based on operational inconvenience, cost, or aircraft retirement plans. The operator also has a right to rely on the FAA’s AMOC approval without needing a separate Australian determination, which is a procedural simplification. There is no explicit right to use a different wiring scheme than the one in the service bulletin, unless that scheme is approved as an AMOC. The duty to maintain records of compliance is implicit: the operator must be able to demonstrate to CASA or an authorised person that the modification was done on time, using the correct parts and instructions. Finally, the directive places a duty on the person who executes the maintenance (the licensed aircraft maintenance engineer or the approved maintenance organisation) to certify the work in accordance with Part 145 of the Civil Aviation Safety Regulations, and that certification becomes the primary evidence of compliance.

Non-compliance with an airworthiness directive issued under the Civil Aviation Act 1988 is a serious matter. The Act provides for civil penalties for contravention of a legislative instrument, which can be imposed by a court. The maximum penalty for a body corporate can reach tens of thousands of dollars per contravention, and for an individual, a lower amount may apply. Additionally, CASA has the power to suspend or cancel the airworthiness certificate of an aircraft that is not maintained in accordance with applicable airworthiness directives, effectively grounding the aircraft until compliance is achieved. This is a powerful enforcement tool because it directly removes the operator’s ability to generate revenue from the non-compliant aircraft. CASA may also issue an infringement notice (a monetary fine) if it considers the breach is minor, or it may refer the matter for criminal prosecution if the non-compliance is deliberate or reckless. The directive itself does not specify a penalty amount; the penalty provisions are in the parent Act and supporting regulations. For operators who knowingly operate an aircraft that does not comply with an AD, there is potential for directors and responsible officers to face personal liability under the Act’s due diligence provisions. The 60-month compliance period is generous, so a court would likely view any failure to meet the deadline as a clear breach unless the operator can show exceptional circumstances beyond its control. The directive also creates a risk that an incident involving smoke or fumes where the flightcrew could not isolate the IFE power might attract additional enforcement action or civil liability, because the directive exists precisely to prevent that scenario. In practice, CASA’s enforcement action is often preceded by a request for information or a show-cause notice. Operators should be aware that the records of compliance (maintenance release, logbook entries, and parts certification) will be examined during routine airworthiness surveillance or post-incident investigations. Missing or inaccurate records are themselves a compliance failure, even if the physical modification was done.

This airworthiness directive operates within a legislative hierarchy. Its immediate legal authority is the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations (CASR), particularly Part 39 which governs the issuance and effect of airworthiness directives. The directive is made by a delegate of CASA and has the force of law as a legislative instrument. It applies to the specific aircraft models and supersedes any inconsistent provision in the aircraft’s type certificate data sheet or the aircraft flight manual unless the contrary is stated. The directive explicitly cross-references FAA AD 2008-23-15 (Amendment 39-15736) and relies on the FAA’s AMOC decisions. This creates a jurisdictional interaction: Australian operators must monitor FAA ADs and FAA approvals to stay compliant, even though the Australian directive does not automatically incorporate every FAA action. For example, if the FAA later issues a new AD that supersedes 2008-23-15, that would not automatically change the Australian directive unless CASA issues a corresponding amendment. The directive also interacts with the general maintenance regulations under CASR Part 145, Part 66 (licensing) and Part 42 (continuing airworthiness). The modification constitutes a major alteration, likely requiring approved data (the service bulletin itself is accepted as approved data if adopted in an AD). The installation must be certified by a licensed aircraft maintenance engineer (LAME) who holds an appropriate category and rating. The directive does not contain any noise or emissions provisions, so it does not interact with environmental regulations. It may have implications for insurance policies: an operator that fails to comply with an AD may find its hull and liability insurance void or the premium increased, because non-compliance with regulatory requirements is a standard exclusion in aviation insurance policies. The directive also interacts with the operator’s air operator certificate (AOC) conditions; the AOC holder is required to maintain all aircraft in an airworthy condition, and non-compliance with an AD is a breach of that condition. There is no express interaction with state or territory workplace health and safety laws, but the safety rationale of the directive relates to protecting workers (crew) and passengers. If a smoke event occurs and the IFE power could not be disconnected, that could be a breach of work health and safety duties as well, but that is ancillary.

The instrument itself is an original directive dated 27 November 2008, signed by James Coyne as a delegate of CASA, and effective from 15 January 2009. There is no amendment history recorded on the face of the document; it appears to be a one-off issuance. However, the directive incorporates the possibility of amendment by reference: it states that later revisions of the named service bulletins, if approved by the FAA as an AMOC to FAA AD 2008-23-15, are acceptable for compliance. This means that the content of the directive can effectively change without CASA reissuing the AD, provided the FAA grants an AMOC. This is a form of dynamic amendment by reference to an external standard, which may create uncertainty because the operator must monitor FAA actions to know the current compliance standard. The directive does not provide for a specific mechanism to update the Australian register when an FAA AMOC is approved. An operator that uses a service bulletin revision that was later approved as an AMOC might need to retain documentation of the FAA approval date to demonstrate that the revision was compliant at the time the work was done. The directive does not provide a sunset clause or expiry date; it continues in force until it is explicitly repealed or superseded by a later CASA instrument. It is possible that the directive has been superseded by later ADs covering the same topic, but that information is not in the source document. In practice, airworthiness directives are eventually consolidated into a new directive if the manufacturer issues a new service bulletin that alters the required actions, but that would be a separate AD number. The current instrument remains the governing Australian directive unless and until CASA replaces it. Operators should check the CASA airworthiness directive database for any subsequent amendments, including editorial corrections or extensions to the compliance time that might have been issued after 2009. The directive’s own text refers only to the FAA AD and the named service bulletins, which suggests it has not been revised or reissued since its original publication.

The source document contains no reference to any litigation, and there is no information provided about court challenges, tribunal appeals, or enforcement proceedings related to this specific directive. In the absence of source material, general observations can be made. It is relatively uncommon for a prescriptive, one-time modification directive of this kind to be litigated in Australia, particularly because the compliance period is generous and the cost of modifying each aircraft, while not trivial, is unlikely to be so high as to justify the expense and reputational risk of challenging a safety instrument. An operator could theoretically apply for judicial review of the directive under the Administrative Decisions (Judicial Review) Act 1977 or the common law, arguing that CASA lacked the power to issue the directive because the unsafe condition was not properly established, or that the directive was procedurally flawed in its consultation or reasons. However, such a challenge would face two hurdles: first, the Civil Aviation Act provides CASA with broad powers to issue ADs, and courts typically give deference to the technical judgment of aviation regulators; second, the 60-month compliance period means the directive does not create an irremediable harm, making interim relief unlikely. If an operator simply ignored the directive and was later prosecuted or had its airworthiness certificate suspended, it might raise a defence that the directive was invalid, but that would be a defensive argument in enforcement proceedings. No such case appears in the public record for this AD. The directive’s reliance on the FAA’s AMOC process could theoretically generate a dispute if the FAA approves a later service bulletin revision that CASA does not recognise, or if the operator uses a revision that later loses FAA approval. But again, no reported litigation has emerged. The absence of litigation does not mean the directive is free from controversy; it may simply reflect that operators have complied, or that disputes are resolved administratively without court action.

Several features of this directive could catch an operator off guard. First, the compliance timeline is not a single date but two linked conditions: the wiring installation must be done by 15 January 2014, but the “other actions” must be done before further flight after that installation. An operator who completes the wiring during a maintenance check and then inadvertently returns the aircraft to service without completing the other actions (for example, a required functional test, a wiring continuity check, or an amended cockpit placard) is immediately non-compliant. The directive does not define what “all other actions” includes, leaving it to the service bulletin. If the bulletin includes tasks that can only be done after the aircraft is out of the hangar, the operator may need to schedule a second downtime or accept the aircraft remaining grounded until those tasks are finished. Second, the directive allows later revisions of service bulletins only if they are approved by the FAA as an AMOC to the FAA AD. An operator who uses a later revision that has not yet received FAA approval, even if it is technically superior, is not compliant with the CASA AD. CASA has not independently approved those revisions; it only accepts the FAA’s AMOC determination. This creates a regulatory gap if the FAA is slow to approve or if the revision covers multiple variants and the AMOC is limited. Third, the directive does not address the handling of aircraft that are already wired with a different system that achieves the same effect (for example, an earlier non-mandatory modification). Unless the operator can show that the existing installation meets the precise requirements of the service bulletin, the directive still applies. There is no equivalency clause in the directive’s text. Fourth, the directive does not mention any requirement for continuing maintenance after the modification; the relays, circuit breakers and wiring become part of the aircraft’s electrical system and must be maintained as such. A future failure of the new relay could mean the aircraft is no longer compliant with the AD, because the flightcrew would lose the ability to cut IFE power. The operator must therefore include these components in its scheduled maintenance program. Fifth, the directive imposes a recordkeeping burden: the operator must be able to prove which service bulletin revision was used, when it was approved by the FAA (if a later revision), and that the installation was done correctly. Failure to maintain records could be treated as a compliance failure even if the modification is physically present. Finally, the directive is 20 years old; operators that have acquired older 767 aircraft since 2009 must verify that the modification was done by the previous owner. Relying on an undocumented assurance could be an expensive mistake.

Compliance with AD/B767/247 requires a systematic, documented process. The first step is to determine which aircraft in the operator’s fleet fall within the applicability paragraph. The directive identifies three sub-groups: 767-200 and -300 aeroplanes listed in Boeing SB 767-24-0152, 767-24-0153, or 767-24-0154; 767-300 aeroplanes listed in SB 767-24-0148, 767-24-0149, 767-24-0150, or 767-24-0151; and 767-400ER aeroplanes listed in SB 767-24-0147. The operator must check each aircraft’s effectivity block in the service bulletins to confirm it is covered. For each affected aircraft, the operator must obtain the correct revision of the applicable service bulletin. The directive mandates the revision dated as listed (e.g., 29 September 2006 for many), but it allows later revisions that the FAA has approved as an AMOC to FAA AD 2008-23-15. The operator should therefore check the FAA’s database or contact Boeing to determine the current approved revision. If the latest revision has FAA approval, use that; otherwise, use the revision specified in the directive. Next, the operator must schedule the modification within the 60-month compliance window (by 15 January 2014). The work includes procuring the required relays, circuit breakers, wiring, terminals, and any other parts specified in the service bulletin’s Accomplishment Instructions. The installation must be performed by a CASA Part 145 approved maintenance organisation or by a licensed aircraft maintenance engineer with the appropriate electrical rating. The engineer must follow the service bulletin exactly, including wire routing, relay mounting, and circuit breaker locations. After the wiring and relay installation is complete, the aircraft must not be returned to service until “all other actions” in the service bulletin are carried out; these typically include operational testing of the new switch function, updating the aircraft’s wiring diagrams, and possibly adding a placard indicating the function of the utility bus switch. The engineer must sign a maintenance release certifying that the work was done in accordance with approved data, and the entry must be recorded in the aircraft logbook or continuing airworthiness record system. The operator should retain copies of the service bulletin used, evidence of FAA approval (if a later revision was used), parts certificates, and the maintenance release. Finally, the operator should include the new components in the aircraft’s maintenance schedule for future inspections. There is no annual recurring compliance date, but the operator must always maintain the modification in an airworthy condition. If an aircraft is acquired after the compliance deadline, the operator must verify that the modification was completed by the original operator, by inspecting the records and visually confirming the installation before operation, because the CASA AD applies to any aircraft that meets the model criteria regardless of ownership history.
