Airworthiness Directives 2004 - Revocation and Remaking - Fokker F27 Series Aeroplanes

The instrument turns on a small number of legal and administrative concepts that appear in its text and Schedule. Those concepts are the levers by which the instrument operates and the words you should read closely in any follow-up work.

• Revocation. The instrument exercises a power to revoke existing Airworthiness Directives. The operative phrase is "revoke the Airworthiness Directives mentioned in Schedule 1". Revocation, in this context, means the prior instruments listed in Schedule 1 cease to operate in the form in which they previously existed.

• Remaking as separate instruments. The instrument does not simply revoke; it simultaneously "make[s], as separate instruments, each Airworthiness Directive mentioned in Schedule 1 and attached". That language signals a structural shift in how the listed ADs will be insulated legally: each AD becomes a distinct instrument attached to this act, rather than remaining in whatever form or compilation they occupied before.

• Delegated administrative action. The instrument is signed by "DAVID ALAN VILLIERS, delegate of the Civil Aviation Safety Authority" and expressly states the statutory source of the delegate's power: "acting under subregulation 39.001 (1) of the Civil Aviation Safety Regulations 1998". The instrument is therefore an exercise of delegated regulatory power.

• Attachment and identity of content. The Note records that "Each attached Airworthiness Directive is being re-made in exactly the same form as appears in the latest published edition of the Directive." That is a statement about substantive identity: the instrument purports not to change the substantive content of each AD, only its footing as a separate instrument.

• Schedule listing and status markers. Schedule 1 functions as the index of the ADs affected. It lists AD numbers and names for the Fokker F27 series. Many entries are annotated "CANCELLED", some have amendment annotations such as "Amdt 1" through "Amdt 7", and a small number are annotated "Superseded by AD/AIRCON/1". The presence of these status markers is part of the administrative record the instrument adopts.

• Aircraft coverage. The Schedule and title identify the class of aircraft to which the instrument relates: "Fokker F27 Series Aeroplanes". This narrows the scope of application to the ADs that concern that aircraft family.

These concepts indicate the instrument is primarily administrative and procedural. It alters the legal form in which existing ADs sit by revoking and reissuing them as separate instruments, while stating an intention not to alter their published content. The instrument does not define Airworthiness Directives, does not list serial-number or individual-aircraft applicability criteria in the supplied text, and does not reproduce the operative wording of the ADs it remakes. For the operative obligations and technical content you must read the attached AD instruments themselves, which the instrument declares are identical to the latest published editions.

The Schedule and title limit the instrument's subject matter to Airworthiness Directives for the Fokker F27 series aeroplanes. From the text, the directly affected parties are therefore the persons, organisations and entities that are subject to those ADs, including:

• Operators and owners of Fokker F27 series aeroplanes. Any obligation in an AD applies to the operator or registered owner responsible for maintenance and airworthiness compliance; the instrument's Schedule shows the universe of ADs that are revoked and remade for that aircraft type.

• Maintenance organisations and certificated engineers who perform required inspections, modifications or replacements mandated by the ADs. Even though the remaking claims to keep AD content identical, the legal form in which compliance is recorded may change and these parties are the ones who implement the work.

• The Civil Aviation Safety Authority and its delegates. The instrument is a delegation exercise by a CASA delegate and therefore affects how CASA manages the AD corpus for the Fokker F27 fleet; it may alter internal record-keeping and the public presentation of ADs.

• Legal advisers, compliance teams and auditors for airlines, lessors, and maintenance providers who must track regulatory instruments. The change to separate instrument form is an administrative change that affects legal citation, version control and possibly document retrieval.

• Registrars and record‑keeping systems that index AD history for aircraft. Where ADs are referenced by number and amendment history in maintenance logs, those references will need reconciliation if instrument identifiers or attachment dates change.

The instrument itself does not include a list of affected operators, serial numbers, or specific legal addressees. It does not, in the supplied text, change the substantive technical obligations of any AD because it expressly remakes each AD "in exactly the same form". Practically, that means the same persons who were subject to the ADs in their published editions remain subject to them after remaking, but the textual evidence in the instrument requires that practitioners check the attached remade ADs to confirm dates, commencement and any transitional provisions that might be present in those attached instruments.

Finally, the Schedule contains numerous entries annotated "CANCELLED" and a few annotated "Superseded by AD/AIRCON/1", which indicates that some listed ADs were already cancelled or superseded in the past. Those status markers affect who needs to act now. For example, an AD marked "CANCELLED" in the Schedule may represent a historical AD that is no longer operative; however the instrument still includes the line and remakes the AD as attached. Affected parties should not assume the presence of the AD number alone means there is an operative requirement without reviewing the attached instrument and the latest published edition cited in the Note.

The instrument itself contains no technical maintenance obligations or explicit rights provisions. Instead it is an administrative vehicle that revokes a set of ADs and remakes them as separate attached instruments, with the stated intention that the remade ADs are identical in substance to the latest published editions. Therefore, the substantive duties and rights that apply to Fokker F27 operators and maintainers will be those contained in the attached ADs, not in this revocation/remaking instrument.

What this means in practical legal terms:

• Duties remain located in the ADs. Any inspection, modification, replacement, reporting or operational restriction that an operator must perform will be prescribed in the individual AD text. This instrument does not amend those prescriptions; it remakes the ADs "in exactly the same form". Practitioners should therefore consult the attached AD documents for precise obligations.

• The instrument creates administrative duties for record-keeping and citation. By remaking ADs as separate instruments, CASA changes the legal form and possibly the instrument numbers, dates, or attachment mechanics by which an obligation is evidenced. Parties responsible for maintenance records, compliance registers, continuing airworthiness documentation and safety management systems must ensure their record‑keeping maps the prior AD instances to the remade instruments to show continuity of compliance.

• Right to information and retrieval. The Note's instruction that attached ADs are identical to the latest published edition implies the attached ADs are available and authoritative. Practitioners therefore have a practical right to access the attached instruments or the "latest published edition" referenced. The supplied text does not include operational details about how to obtain the attachments, so rights of access will be exercised by retrieving the attached ADs from CASA or its publications.

• Delegation and decision-making. The instrument records the decision-maker: a named delegate of CASA acting under subregulation 39.001(1). That identifies the administrative decision-maker for a challenge or review process. The instrument does not state a review or merits appeal path; those procedures, if any, will be governed by the general administrative or aviation regulatory framework rather than this instrument.

• Continuity of obligations. Because the instrument remakes ADs identically, operators retain the duties previously imposed under the published ADs; there is no textual basis in this instrument to assert a substantive reduction or expansion of duties. Any right to contest the substantive content of an AD must therefore be pursued against the AD itself or under the general regulatory review mechanisms rather than against this revocation/remaking instrument.

In short, the instrument is a mechanism that changes the legal packaging of the AD corpus for the Fokker F27. It creates duties in the sense that it requires practitioners to reconcile records and ensure compliance with attached ADs. The instrument does not, in the supplied text, confer discrete rights or exemptions, nor does it specify enforcement or penalty mechanisms; those matters are deferred to the text of the ADs themselves and to the Civil Aviation Safety Regulations under which the delegate acted.

The instrument as supplied does not include any penalty provisions or enforcement steps. It is a formal revocation and remaking exercise and does not itself specify sanctions, infringement notices, or enforcement processes. The only enforcement‑related content in the instrument is the record of authority: the delegate acts "under subregulation 39.001 (1) of the Civil Aviation Safety Regulations 1998", which identifies the statutory source for the administrative action, but the instrument does not reproduce any enforcement provisions from that regulation.

As a practical proposition grounded in the text:

• This instrument does not state penalties. There is no clause in the supplied text that creates an offence, sets a fine, or prescribes enforcement practices. Any civil or criminal penalties that attend non‑compliance with airworthiness requirements will therefore be contained in the individual AD instruments or in the wider Civil Aviation Safety Regulations. Practitioners must consult those texts for enforcement consequences.

• Enforcement responsibility is implicit. Because the instrument is an exercise by a CASA delegate, the enforcement of the remade ADs will fall within CASA's regulatory remit. The instrument itself does not describe operational enforcement steps, surveillance regimes, or inspection powers. Any enforcement action will rely on the usual CASA administrative and regulatory tools, which are not enumerated here.

• Status markers affect enforcement applicability. Schedule 1 includes many entries marked "CANCELLED" and a few marked "Superseded by AD/AIRCON/1". Those markers indicate that some of the listed ADs may not impose enforceable duties at present because they have been cancelled or superseded. The supplied instrument, however, includes them in the list to be revoked and remade; to determine whether a listed AD currently carries enforceable requirements, practitioners must check the attached remade AD text and the "latest published edition" referenced in the Note.

• Evidence and proving compliance. Because the instrument changes the legal form of the AD into a separate instrument, proving historical compliance could require mapping older versions to the remade instruments in maintenance records. The instrument contains no transitional or evidentiary language; ensuring continuity of proof will therefore be a matter for operators, maintainers and CASA interactions.

In short, enforcement consequences are not set out in this instrument. The supplied text places the exercise of revocation and remaking on statutory authority but leaves penalties and procedural enforcement frameworks to be found in the ADs themselves and in the Civil Aviation Safety Regulations, which are not reproduced in the supplied instrument.

The instrument expressly situates itself within the Civil Aviation Safety regulatory scheme by invoking delegated power under "subregulation 39.001 (1) of the Civil Aviation Safety Regulations 1998". That single cross-reference is the only explicit linkage to other law in the supplied text. The interaction points you should note from the instrument are these:

• Delegated power under the CASR. The instrument is an exercise of power delegated under a CASR subregulation. The substantive content and validity of the instrument depend on the scope and terms of that subregulation and the surrounding regulatory architecture. The supplied text does not reproduce the subregulation. Therefore, to fully understand limits, remedies and interaction with other statutory provisions you must read subregulation 39.001(1) and the wider CASR provisions governing ADs.

• Supersession and cancellation relationships. Schedule 1 contains entries annotated "Superseded by AD/AIRCON/1" (for AD/F27/59 and AD/F27/60) and many entries marked "CANCELLED". Those annotations indicate prior interactions among AD instruments where one AD has been replaced by another or cancelled. This instrument interacts with that web of prior AD decisions by formally revoking and remaking the ADs included in the Schedule. The presence of "Superseded" and "CANCELLED" entries in the Schedule signals that ADs do not exist in isolation but as part of a corpus of directives that have historically replaced or cancelled each other.

• Relationship to published editions. The Note states each attached AD is remade "in exactly the same form as appears in the latest published edition of the Directive." That ties the instrument to an external body of published material. The legal identity and content of the remade ADs thus interact with publication practice and with whatever administrative record CASA maintains of published AD editions.

• No expressed interaction with other statutes. The instrument does not reference civil aviation Acts, administrative law remedies, or other statutes. If interactions to consider include rights of judicial review, administrative appeal or penalties, those will need to be located in the CASR or primary statutes; the supplied text does not address them.

• Practical cross‑reference with maintenance and airworthiness law. Because ADs typically implement continuing airworthiness obligations, the remade ADs will interact with maintenance contracts, aircraft airworthiness records, and obligations under air operator certificates. The instrument itself does not specify how compliance with remade ADs will be recorded or how older compliance entries will be deemed to map onto the remade instruments; this is an interaction point that operational parties will have to resolve administratively.

In short, the instrument is explicitly anchored to the CASR by reference to the delegate's authority, and implicitly interacts with the AD publication corpus and the history of prior AD cancellations and supersessions. The supplied text does not reproduce the CASR provisions or any other statute, so the practical legal interactions beyond the delegation reference must be established by consulting the CASR and the remade AD attachments.

The instrument itself is dated 20 December 2004 and records a single administrative action: the revocation and remaking of the ADs listed in Schedule 1. The supplied Schedule, however, contains internal amendment markers that reflect prior amendment activity to individual ADs over time. The instrument does not provide a historical narrative, but you can extract amendment metadata from the Schedule entries. Relevant points drawn from the Schedule:

• Many AD entries carry amendment annotations. For example the Schedule lists "CANCELLED AD/F27/22 Amdt 1", "CANCELLED AD/F27/69 Amdt 7", "Structural Limitations AD/F27/103 Amdt 7", "Godfrey Engine Driven Cabin Supercharger Drive Quill Shaft - Modification AD/F27/62 Amdt 2", and "Ageing Aircraft Modifications AD/F27/130 Amdt 3". These markers indicate that specific ADs went through one or more formal amendments prior to inclusion in this Schedule.

• Several ADs are annotated with different amendment numbers across the list. The highest amendment number shown in the supplied Schedule is "Amdt 7" for AD/F27/69, indicating that at least one AD had been amended multiple times before December 2004.

• Cancellation and supersession markers. The Schedule contains numerous entries that are labelled "CANCELLED" and a couple annotated "Superseded by AD/AIRCON/1" (AD/F27/59 and AD/F27/60). Where the Schedule lists an AD as cancelled or superseded, that is a record of prior amendment or revocation activity for that AD.

• This instrument itself is an amendment-style administrative measure. While it does not amend the substantive content of the ADs (the Note insists the remade ADs are identical to the latest published edition), it changes the administrative status of those ADs by revoking earlier instruments and creating separate attached instruments. That change in legal form is a kind of statutory housekeeping amendment to the corpus of ADs.

• No chronological amendment trail in the supplied text. The instrument does not provide dates of the original ADs, the dates of their prior amendments, or the dates they were cancelled or superseded. Those details will appear only in the ADs' publication history or in CASA records. The Schedule, however, provides a snapshot of AD numbers and their last-known amendment or cancellation annotation by December 2004.

For practitioners reconstructing regulatory history, the Schedule is useful as an index showing which ADs existed for the Fokker F27 series up to AD/F27/157 and which of those had amendment markers or cancellation annotations. To understand the substantive amendment history of any single AD you must obtain the attached remade AD (which the instrument says matches the latest published edition) and any prior versions or publication logs held by CASA.

The supplied instrument contains no record of litigation, judicial review, administrative appeals, or court decisions concerning the revocation and remaking exercise or any of the ADs listed in Schedule 1. There are no case names, judgments or references to disputes in the text.

From the instrument alone, therefore:

• There is no litigation history recorded. The instrument is a formal administrative instrument and contains no references to challenges or judicial determinations.

• If litigation or administrative review has occurred (for example, a challenge to the content of an AD or to the exercise of delegated power), that material is not present in the supplied text and must be sought in court records or CASA administrative files outside this instrument.

• The instrument identifies the decision-maker by name and delegation basis. For any prospective review or record search, that identifying information (the delegate's name and the subregulation cited) provides the relevant administrative hook for records requests and for any legal challenge tracing chain of delegation.

Practitioners who need to know whether any of the remade ADs have been the subject of litigation must consult judicial databases, administrative tribunal records and CASA correspondence archives. None of that material is reproduced in the instrument you were given.

Several practical and legal pitfalls arise from the structure and content that appear in the supplied instrument and Schedule. These are not normative judgements; they are concrete issues to check when advising clients or managing compliance.

• Attachment versus text absence. The instrument states that each AD is attached and remade "in exactly the same form as appears in the latest published edition of the Directive." The supplied text does not include those attachments. Do not assume the full operative AD text is in the instrument you have; obtain the attached remade ADs or the latest published editions to see the operative obligations, commencement dates and any transitional provisions.

• "CANCELLED" entries are present in the Schedule. The Schedule lists many AD numbers with the word "CANCELLED" prefixed. That can be confusing: the instrument purports to revoke and remake the ADs listed, but many are already marked cancelled. Practitioners must verify whether an AD marked "CANCELLED" in the Schedule signifies that there is no operative requirement, or whether the remade attached AD reintroduces content for historical or record‑keeping reasons. Do not rely on the mere presence of an AD number for enforceable obligations without reading the attached AD.

• "Superseded" entries. Two entries explicitly read "Superseded by AD/AIRCON/1". Where an AD has been superseded by another AD, check which instrument currently prescribes the operative requirement. Supersession relationships in the AD corpus affect which document an operator must obey.

• Amendment annotation ambiguity. The Schedule contains amendment markers such as "Amdt 1" through "Amdt 7". Those markers indicate previous amendments, but they do not disclose the content of those amendments or their effective dates. If a compliance action references an amendment number, you must obtain the remade AD or the CASA publication history to confirm exactly what changes occurred.

• Citation and recordkeeping differences. Because the instrument remakes ADs "as separate instruments", the way an AD is cited in legal filings, maintenance logs and compliance registers may change. Practitioners should synchronise internal citations with the remade instrument identifiers to avoid later evidentiary disputes about which version of an AD was complied with.

• Absence of enforcement and penalty language. The instrument contains no enforcement or penalty details. If a client needs to understand the legal consequences of non-compliance, you must consult the remade ADs and the Civil Aviation Safety Regulations, because this instrument does not specify those consequences.

• Continuity of compliance proof. Remaking an AD without changing substantive content does not automatically ensure smooth evidentiary continuity in maintenance records. Maintenance files that reference the pre‑revocation AD number or date will need cross-referencing to the remade instrument to prove continuous compliance. The instrument provides no transitional or savings clause to assist with that mapping.

• Delegation trace must be confirmed. The instrument identifies a CASA delegate by name and the subregulation authorising the action. For a challenge or administrative request, confirm the delegate's authority was properly exercised under the cited provision because the instrument itself does not record the procedural steps taken to delegate or exercise that power.

• Scope restraint to Fokker F27. The instrument relates only to ADs listed in Schedule 1 for "Fokker F27 Series Aeroplanes". Do not generalise its administrative model to other aircraft types without checking whether separate instruments exist for them.

In short, the main practical go‑to for any practitioner is to obtain and read the attached remade ADs and the CASA published editions the Note references, cross-check cancellation and supersession markers, and reconcile internal records with any change in how ADs are presented or cited.

Compliance with the regime reflected by this instrument is a two-step exercise grounded in what the instrument does and in the substantive AD texts it remakes.

1. Obtain the remade ADs. The instrument states each AD is made "as separate instruments" and attached, and that each attached AD is "in exactly the same form as appears in the latest published edition of the Directive." The supplied text does not include those attachments. Your first compliance action is to retrieve the attached remade AD documents or the CASA "latest published edition" copies of each AD listed in Schedule 1. These contain the operative inspection, modification or reporting requirements.

2. Confirm applicability to specific aircraft. Each AD will specify scope, affected serial numbers, or other applicability criteria. Do not assume every AD in the Schedule applies to every Fokker F27 in a fleet. Read the scope clauses in the remade ADs and match them to aircraft by registration and serial number.

3. Map historical compliance records. Because the instrument revokes prior AD instruments and remakes them, reconcile your maintenance records, logbooks and continuing airworthiness files to ensure that historical compliance entries are mapped to the remade AD instrument identifiers. Where earlier entries cite amendment numbers or prior AD identifiers, create a cross-reference table showing equivalence to the attached remade instruments.

4. Confirm whether listed ADs are operative. The Schedule contains many entries marked "CANCELLED" and a few marked "Superseded by AD/AIRCON/1". For any AD you believe imposed a duty, confirm whether it remains operative or was historically cancelled or superseded. For cancelled ADs verify whether the attached remade instrument restates the cancellation or whether the remade instrument contains substantive obligations.

5. Observe deadlines and actions in remade ADs. Follow the inspection intervals, modification deadlines, and any reporting obligations set out in the remade ADs. Because the instrument states the remade ADs are identical to the latest published editions, the operative timeframes will be those published. Implement the work through certificated maintenance organisations or authorised engineers as required by the AD text.

6. Update compliance registers and safety management systems. Reflect the remade AD instrument identifiers in safety management systems, continuing airworthiness assurance records and compliance registers used for audits or regulatory inspections. Maintain documentary proof (job cards, inspection reports, parts replacement records) showing dates, personnel and certification of compliance.

7. Seek clarification from CASA if ambiguous. If an AD in the remade set appears to conflict with other ADs, contains unclear applicability, or the Schedule marking suggests cancellation/supersession complexity, seek formal clarification from CASA. The instrument identifies the decision as taken by a CASA delegate under subregulation 39.001(1), so CASA is the administrative source for any interpretative guidance.

8. Legal and audit checks. For contractual or insurance-sensitive work, obtain legal confirmation that the remade AD text provides continuity of legal obligation, and ensure external auditors or lessors are supplied with the remade AD texts and the record cross-references you have created.

9. Monitor for further AD activity. The instrument is a snapshot. ADs are regularly issued, amended, superseded or cancelled. Keep monitoring CASA's published ADs to capture future technical directives that may alter obligations for Fokker F27 aircraft.

10. Preserve evidence of compliance during the remaking transition. Because the instrument changes legal form, preserve all original documents demonstrating prior compliance in case CASA or third parties request historical proof demonstrating continuity across revocation and remaking.

These steps follow directly from the instrument's mechanics: it revokes and remakes ADs without changing substance but changes how those ADs will be presented and cited. Ensuring compliance therefore requires treating the remade ADs as the operative instruments and reconciling past records with the new instrument forms.
