AD/A330/49 - Equipment/Furnishings - Non Textile Floor (NTF) Replacement

The AD is organised around a small number of concrete technical and compliance concepts drawn directly from its text.

• Applicability. The AD applies to “all Airbus A330 aircraft, fitted with Non Textile Floor (NTF) Part Number (PN) 440444‑75050BCV, 440458, 440458OK, 440488, 440489, 440497, 440499, 440501, 422225020 NTF 'Flight Floor ATS' from vendor Benecke‑Kaliko and Gôppinger‑Kaliko” (Applicability). This is a part‑number and vendor‑based scope; it does not limit applicability by serial number, airline, or operator status. The AD further notes that the listed part numbers were embodied in production via one or more of a list of Airbus modification numbers, and that they “may have also been embodied in‑service by application of operator cabin modifications” (Background).

• Replacement requirement. The central substantive requirement is a replacement obligation: replace the affected NTF with an NTF “for which the composition (NTF top layer plus adhesive plus phenolic laminate) fulfils the applicable requirements” (Requirement). The AD does not specify a particular supplier or replacement part number; it specifies a compositional standard for the installed assembly.

• Procedure reference. The AD directs that replacement be performed “in accordance with procedures described in Airbus AMM 25‑28‑12/42 PB 401” (Requirement). That manual reference identifies the procedural pathway operators must follow to carry out the physical work.

• Compliance timing. The AD sets an explicit compliance deadline of “No later than 31 March 2009” and indicates the AD became effective on 12 May 2005 (Compliance; Effective date). The directive is dated 31 March 2005 and signed by a CASA delegate (signature and date lines).

• Safety premise. The stated technical premise is that the installed composition failed the 12‑second vertical burn test in accordance with JAR/FAR §25.853, despite components having initially passed that test when considered alone (Background). The AD therefore treats the installed stack composition as the compliance criterion rather than the individual top layer alone.

• Cross‑referenced materials. The AD refers to DGAC AD F‑2005‑040 and Airbus SIL 25‑131 (Requirement), signalling related foreign regulator action and Airbus service information that the operator may need to consult.

Together these concepts yield a straightforward regulatory mechanism: identify affected aircraft, follow a prescribed AMM replacement procedure, and ensure the newly installed NTF assembly meets the burn‑performance criterion, all by the stated deadline.

The AD’s language and structure identify the obligations as landing on operators and entities responsible for continuing airworthiness of Airbus A330 aeroplanes fitted with the listed NTF part numbers from the two named vendors.

• Affected aircraft and operators. Applicability is framed by aircraft type plus installed part numbers: “All Airbus A330 aircraft, fitted with Non Textile Floor (NTF) Part Number … from vendor Benecke‑Kaliko and Gôppinger‑Kaliko” (Applicability). That formulation obliges whoever operates or maintains an A330 that carries those part numbers to take action. The AD does not carve out particular operators, lessors, or maintenance organisations; it applies to every A330 with affected parts.

• Maintenance organisations and maintenance personnel. The AD requires replacement “in accordance with procedures described in Airbus AMM 25‑28‑12/42 PB 401” (Requirement). That invokes the operator’s or approved maintenance organisation’s responsibility to execute maintenance tasks in conformity with the AMM. Personnel executing the replacement must follow the specified AMM procedures and any related limitations or tooling referenced in that AMM section.

• Supply chain participants. While the AD does not name replacement part suppliers, it refers to the composition criteria of the top layer, adhesive and phenolic laminate (Requirement). Suppliers of replacement NTF, adhesives and laminates will therefore be indirectly affected because replaced assemblies must demonstrate a composition that fulfils the applicable burn‑test requirements. The AD itself does not specify certification documents or supplier obligations; operators will need to secure replacement assemblies and any supplier assurances or test data necessary to establish that the installed composition meets requirements.

• Continuing airworthiness decision‑makers. The AD’s identification of particular Airbus production modifications that embodied the listed NTF part numbers (Background: list of modification numbers) imposes a record‑review task on continuing airworthiness managers, who must check production and in‑service modification records to determine which aircraft are fitted with the affected NTFs. The AD explicitly flags that these NTF part numbers “may have also been embodied in‑service by application of operator cabin modifications” (Background), meaning the presence of the part number may be the result of later cabin modification work as well as original production configuration.

• Regulatory and oversight authorities. The AD references DGAC AD F‑2005‑040 and Airbus SIL 25‑131 (Requirement), indicating that other regulators and the manufacturer have issued related materials. CASA’s issuance places the onus on operators under Australian regulatory oversight to comply with the directive for aircraft under its jurisdiction.

The AD does not specify who must pay for the work, who supplies parts, or any certification paperwork beyond the AMM procedures and composition requirement. Those allocation questions are therefore to be resolved in practice by the affected operators, lessors and maintenance providers under their contractual and regulatory arrangements.

The AD contains precise duties and limited procedural directions and leaves other matters unstated. Set out below are the duties imposed by the text and the rights and open questions that remain apparent from the AD.

Duties imposed by the AD

• Identify applicability. Operators must identify whether their A330 aircraft are fitted with any of the listed NTF part numbers supplied by Benecke‑Kaliko or Gôppinger‑Kaliko (Applicability; Background). The AD provides the part numbers and notes production modification numbers by which they were incorporated.

• Replace the affected NTF. Operators must replace affected NTF assemblies with NTFs “for which the composition (NTF top layer plus adhesive plus phenolic laminate) fulfils the applicable requirements” (Requirement). The replacement is a mandatory action under the AD.

• Use specified procedures. The replacement must be carried out “in accordance with procedures described in Airbus AMM 25‑28‑12/42 PB 401” (Requirement). The AMM reference constrains the procedural method, likely including steps, tooling and acceptance checks found in that AMM section.

• Meet deadline. Replacement must be completed “No later than 31 March 2009” (Compliance). The AD also records its effective date and issuance date (Effective date; signature date).

Rights, information obligations and gaps left by the AD

• Right to choose compliant replacement parts. The AD sets a compositional performance standard for the installed assembly rather than mandating a particular manufacturer’s part number for replacement (Requirement). That leaves operators free to source any replacement NTF that demonstrably meets the composition and burn‑test requirements, subject to the AMM procedures.

• Documentation and proof. The AD does not prescribe the documentary form of certification that the replacement NTF composition meets the applicable requirements. The text does not specify whether supplier data sheets, test certificates, or post‑installation testing are required to demonstrate compliance. The AMM may contain relevant recording requirements, but the AD itself does not specify them.

• Absence of explicit allocation of cost or service provision. The AD does not address who bears financial responsibility for replacement, how downtime is to be scheduled, or whether CASA or Airbus will assist sourcing parts. Those remain commercial and operational matters to be resolved by operators and maintenance organisations.

• No specified enforcement mechanism or penalties within the text. The AD sets obligations and deadlines but does not itself state penalties or enforcement procedures (see Penalties and enforcement). Operators must therefore be attentive to CASA’s broader regulatory framework for consequences of non‑compliance, which the AD does not replicate verbatim.

In short, the AD imposes identification, procedural and timing duties and leaves open matters of supplier selection, documentary proof of compositional compliance and commercial responsibility.

The AD text supplies no express penalty regime, sanction schedule, or enforcement mechanism. The instrument states the mandated replacement requirement, the applicable AMM procedures to follow, the effective date and the compliance deadline (Requirement; Effective date; Compliance), but it does not include language specifying fines, licence consequences, or steps CASA will take to enforce compliance.

What the AD does state about enforceability and timing

• Effective and compliance dates. The AD “becomes effective on 12 May 2005” and requires replacement “No later than 31 March 2009” (Effective date; Compliance). Effective dates create the start point from which compliance obligations run; the compliance deadline is the latest permitted date for completing the required action.

• Signature and authority. The AD is signed by a Delegate of the Civil Aviation Safety Authority (David Villiers), dated 31 March 2005 (signature block). That signature indicates the administrative source of the directive and its formal issuance by CASA.

What the AD does not state

• The AD does not identify any specific penalties, enforcement powers, inspection frequency, or audit procedures associated with failure to comply. It does not state whether CASA will issue continuing legal notices, grounding directions, certificates of airworthiness consequences, monetary penalties or other administrative sanctions. Those mechanisms, if any, are not described in the AD text provided.

Implications for operators and maintainers

• Operators should not infer from the absence of explicit penalty language that non‑compliance is risk‑free. The AD creates an explicit regulatory obligation and a compliance deadline. In most regulatory frameworks, failure to comply with an AD is an unacceptable risk to continued airworthiness and can lead to enforcement action under broader aviation safety legislation and regulation, though that is outside the four corners of this AD text. The AD itself does not set out those downstream enforcement steps.

• Because the AD requires replacement to procedures in an Airbus AMM section, CASA or authorised inspectors are likely to review maintenance records showing that the AMM procedure was followed and that the replacement NTF composition meets the stated requirements. The AD does not specify record retention requirements or acceptance criteria for documentary evidence.

In summary, the AD imposes clear technical and timing obligations but is silent within its text on the specific penalties or enforcement processes that may follow non‑compliance.

The AD expressly references other regulatory and manufacturer materials, and it anchors the composition requirement to an established burn‑performance standard that it cites. The text itself is limited to those references and does not expressly state broader legislative interactions.

Cross‑references in the AD

• JAR/FAR §25.853. The Background states that the NTF assemblies initially “passed the 12 second vertical burn test in accordance with JAR/FAR §25.853 requirements” when tested alone, but that the installed composition failed that 12‑second vertical burn test (Background). By invoking JAR/FAR §25.853, the AD situates its performance requirement within the internationally recognised burn test criterion referenced.

• DGAC AD F‑2005‑040. The Requirement notes “DGAC AD F‑2005‑040 and Airbus SIL 25‑131 refers.” That indicates a related airworthiness directive issued by the French Direction Générale de l’Aviation Civile (DGAC) and implies that corresponding action had been taken or recommended by a foreign regulator. The AD thus cross‑links CASA’s action to contemporaneous regulatory activity elsewhere.

• Airbus SIL 25‑131. The AD also references Airbus Service Information Letter 25‑131 (Requirement). That letter is a manufacturer communication likely addressing the same problem and providing guidance, but the AD does not reproduce that material. Operators are signalled to consult those external documents in addition to the AMM.

Interaction consequences and limits of the AD text

• The AD makes the AMM the procedural vehicle for replacement (Requirement). That places the AMM in an operationally prescriptive relationship with the AD: the AMM contains the maintenance steps an operator must follow to meet the AD. The AD does not attempt to restate the AMM procedures.

• The AD’s invocation of JAR/FAR §25.853 situates the required compositional outcome within a pre‑existing regulatory safety standard, but the AD does not specify testing methodology, pass/fail criteria beyond the mention of the 12‑second vertical burn test, nor how evidence that the installed composition meets those requirements should be documented or demonstrated.

• The AD does not discuss interaction with lease agreements, warranty claims against suppliers, or commercial contracts governing maintenance. Those are outside the AD text and must be addressed by the parties involved in practice.

In short, the AD interacts with two types of external material: (1) certification and burn‑test standards (JAR/FAR §25.853) and (2) related regulator and manufacturer communications (DGAC AD and Airbus SIL), and it refers operators to the Airbus AMM for the required replacement procedures. The AD itself does not adjudicate conflicts among those materials or provide procedural detail beyond the AMM reference.

The AD text provided contains a single issuance and does not include any amendments, rescissions, or replacement ADs within the document. The items in the AD that pertain to its temporal and amendment characteristics are:

• Issue and signature date. The AD is signed and dated 31 March 2005 by a CASA delegate (signature block). That date appears in the AD body and the signature block.

• Effective date. The AD “becomes effective on 12 May 2005” (Effective date). That is the date on which the mandated requirements became operative.

• Compliance deadline. The AD sets a compliance deadline of “No later than 31 March 2009” (Compliance).

• No amendment history recorded in the text. The printed AD does not include any subsequent amendment notes, later AD numbers, superseding AD references, or revision annotations. The document also does not include an “Amendments” or “History” section.

Because the AD references DGAC AD F‑2005‑040 and Airbus SIL 25‑131 as related material, operators should verify whether CASA issued any later ADs, amendments or airworthiness notices that superseded or modified this AD after its effective date, but such follow‑on actions are not recorded in the AD content provided.

For those compiling compliance plans or audit trails, the version history available in this AD is therefore limited: the AD as presented reflects the initial issuance and the single given compliance timetable, with no internal record of amendments. Any subsequent regulatory changes or further CASA action would need to be located in CASA’s AD database, subsequent AD publications, or aviation safety bulletins beyond the text supplied here.

The AD itself contains no reference to litigation, legal challenges, court decisions, tribunals, or dispute resolution related to its issuance, content, or enforcement. There are no cases named or legal proceedings cited in the AD text.

What the AD does indicate about potential legal avenues

• The AD is an administrative regulatory instrument directed to continuing airworthiness and does not purport to summarise or list litigation or appeals. The directive simply sets technical obligations and a compliance schedule. The AD does not include any statements about rights of review, internal CASA appeal mechanisms, or judicial review.

• Because the AD is silent on litigation or dispute resolution, any party wishing to challenge the AD, contest enforcement action, or seek relief would need to rely on the administrative law and judicial review avenues available under Australian aviation legislation and general administrative law. Those procedural pathways are not described or referenced within this AD.

In short, the AD contains no litigation history or case citations and provides no internal record of any legal challenge. The document does not identify or name cases.

Several practical and technical pitfalls arise directly from the AD’s wording. These are matters the AD either requires or leaves unspecified and that may be material to planning, recordkeeping and execution.

• Part‑number specificity and search complexity. The Applicability lists a group of part numbers (440444‑75050BCV, 440458, 440458OK, 440488, 440489, 440497, 440499, 440501, 422225020). Operators must check aircraft records to locate any of these PN variants. The list includes multiple similar PNs (for example 440458 and 440458OK) and a long alphanumeric PN (440444‑75050BCV), which increases the risk of overlooking an effected PN in inventory or maintenance records if searches are not precise (Applicability).

• Composition, not just top layer or PN, is the compliance axis. The AD requires replacement with NTF “for which the composition (NTF top layer plus adhesive plus phenolic laminate) fulfils the applicable requirements” (Requirement). That wording focuses on the installed stack composition rather than an individual visible surface or a single part number. An operator that assumes compliance is demonstrated by replacing only the top layer, or that relies on a supplier’s top‑layer certification alone, risks non‑compliance if the adhesive or laminate in the final installed assembly fails the burn requirement.

• Evidence of compositional compliance is unspecified. The AD does not set out what documentary or test evidence will be accepted to show the installed composition fulfils the applicable requirements. Operators must therefore decide how to demonstrate compliance in practice , for instance through supplier certificates, material test reports, or other substantiation , but the AD does not prescribe the method.

• Production versus in‑service embodiment. The Background lists a set of Airbus production modification numbers by which the listed NTF part numbers were embodied in production (40413, 40716, 43894, 46163, 46164, 46778, 46794, 47780, 47788, 47816, 47846, 48189 or 48598) and explicitly warns that the parts “may have also been embodied in‑service by application of operator cabin modifications” (Background). Operators must therefore check both factory production records and subsequent in‑service modification records to identify affected aircraft.

• Procedural dependency on Airbus AMM. The AD requires replacement “in accordance with procedures described in Airbus AMM 25‑28‑12/42 PB 401” (Requirement). Access to the correct AMM revision and interpretation of any limitations or notes in the AMM is therefore essential. Misinterpretation or use of an incorrect AMM revision could produce non‑conforming maintenance actions.

• Time horizon and scheduling. The compliance date is 31 March 2009, with the AD effective 12 May 2005 (Compliance; Effective date). The AD gives a multi‑year window for replacement, which requires fleet planning and scheduling to ensure each affected aircraft is modified before the deadline. Operators that delay replacement until late in the compliance window may face resource shortages or competing maintenance priorities.

• Cross‑reference materials not reproduced. The AD refers to DGAC AD F‑2005‑040 and Airbus SIL 25‑131 (Requirement). Those documents likely contain additional advice, but their contents are not reproduced in this AD. Operators must retrieve and review those documents to ensure they are not missing essential technical or procedural guidance.

• No express guidance on proof of compliance in the AD. Because the AD does not state the form of records, testing, or certification required to prove the replacement and compositional compliance, operators should treat recordkeeping conservatively and maintain supplier test reports, installation records and AMM sign‑offs to evidence compliance.

These are concrete procedural and evidential risks that follow directly from the AD’s precise text. Addressing them requires deliberate record searches, supplier engagement and clear documentation practices.

The AD prescribes the core compliance actions and leaves operational detail to the referenced AMM and to associated manufacturer and regulator communications. The following is a practical step‑by‑step compliance checklist distilled from the AD language and the specific actions it mandates.

1. Identify affected assets

• Compile a list of all Airbus A330 aeroplanes under your operational control.
• Examine maintenance records, production configuration data and modification history for each airframe to determine whether any of the listed part numbers (440444‑75050BCV, 440458, 440458OK, 440488, 440489, 440497, 440499, 440501, 422225020) are installed (Applicability; Background).
• Cross‑check the production modification numbers listed in the AD (40413, 40716, 43894, 46163, 46164, 46778, 46794, 47780, 47788, 47816, 47846, 48189, 48598) to identify aircraft produced with the affected NTFs (Background).
• Review in‑service cabin modification records because the AD expressly notes the listed PN “may have also been embodied in‑service by application of operator cabin modifications” (Background).

2. Consult the referenced materials

• Obtain and review the Airbus AMM 25‑28‑12/42 PB 401 to learn the required removal and installation procedures the AD mandates for the replacement action (Requirement).
• Retrieve and review DGAC AD F‑2005‑040 and Airbus SIL 25‑131 as referenced in the AD to capture any additional guidance or recommendations that pertain to the same issue (Requirement).
• Keep copies of the AMM revision used and any associated service letters for auditability.

3. Select compliant replacement NTF assemblies

• Source replacement NTF assemblies whose combined composition , top layer, adhesive and phenolic laminate as installed , satisfies the applicable burn requirements referenced by the AD (Requirement; Background). The AD requires a compositional outcome: “fulfils the applicable requirements”.
• Obtain material specifications, test reports or supplier confirmations that the installed assembly meets the 12‑second vertical burn criterion in accordance with JAR/FAR §25.853, because the Background identifies that criterion as the relevant standard (Background). The AD does not prescribe the precise form of evidence; keep conservative documentary records.

4. Schedule and execute the replacement per the AMM

• Plan the maintenance tasks in accordance with the AMM procedures (AMM 25‑28‑12/42 PB 401). Ensure qualified personnel and required tooling are scheduled and available, and that the AMM revision used is recorded.
• Perform removal of the affected NTF and installation of the compliant NTF strictly following the AMM instructions and any Airbus or CASA guidance.

5. Record and retain evidence of compliance

• Record the work order, AMM reference and revision, part numbers removed and installed, batch/lot/serial numbers of replaced components, and supplier documentation demonstrating compositional compliance.
• Retain documentation in the aircraft’s continuing airworthiness records so that compliance with the AD can be demonstrated to CASA or auditors.

6. Complete the work by the deadline

• Ensure each affected aircraft completes the replacement “no later than 31 March 2009” (Compliance). Track progress across the fleet and prioritise aircraft nearing the deadline.

7. Liaise with suppliers and manufacturer if questions arise

• If there is uncertainty whether a candidate replacement assembly meets the composition requirement, seek technical clarifications from Airbus and the NTF supplier, and consult the DGAC AD and Airbus SIL referenced in the AD for additional technical guidance.

8. Verify regulatory status and follow‑ons

• Although the AD itself does not state penalties, operators should proactively confirm with CASA any preferred formats for demonstrating compliance, and ascertain whether CASA requires submission of inspection or acceptance records following the replacements.

This sequence follows the AD’s explicit instructions: identify affected aircraft (Applicability and Background), perform the replacement per Airbus AMM 25‑28‑12/42 PB 401 (Requirement), ensure the installed composition meets the burn criteria (Requirement; Background), and complete the work by the stated deadline (Compliance). The AD does not prescribe supplier selection, proof formats, or cost allocation; those must be resolved by operators in commercial and maintenance arrangements while keeping conservative documentary evidence to show compliance.
