Airworthiness Directives 2004 - Revocation and Remaking - Teledyne Continental Motors Piston Engines

The instrument relies on three interlocking concepts: revocation, remaking (re-issuance), and equivalence to the “latest published edition” of an AD. Revocation is performed by paragraph (a) which expressly revokes the Airworthiness Directives mentioned in Schedule 1. Remaking is performed by paragraph (b) which makes, as separate instruments, each AD mentioned in Schedule 1 and attached. The declared equivalence is in the Note which states that each attached AD is re-made in exactly the same form as appears in the latest published edition of the Directive.

The Schedule functions as the operative index. It lists AD names and AD numbers and annotates some entries as "CANCELLED" and others with amendment numbers. These annotations indicate prior administrative actions affecting those ADs (cancellation or amendment), and they are themselves part of the record the delegate used when revoking and remaking. The list is explicitly limited to Teledyne Continental Motors piston engines by the Schedule heading.

Legal authority: the delegate acts under subregulation 39.001(1) of CASR 1998. The instrument does not reproduce the wording of that subregulation, but it cites it as the power under which the delegate acts. The mechanics therefore are framed as an exercise of delegated regulatory power under the CASR regime.

Treatment of content: the instrument does not purport to change substantive requirements contained in any AD. The Note states the remade ADs are "in exactly the same form" as the latest published edition. Thus the main concepts emphasise administrative repositioning of the ADs rather than substantive amendment. The instrument therefore creates continuity of content while altering the statutory form and citation path by making each AD a separate instrument attached to this revocation/remaking instrument.

Document practice and publication: because the remade ADs are attached as separate instruments, users are required to consult those attachments or the "latest published edition" to know the operative compliance text. The Schedule itself is an index, not the operative compliance content. Some Schedule entries are marked as CANCELLED, which introduces a specific administrative concept: an AD previously cancelled remains listed for revocation and remaking in this administrative sweep. The presence of amendment markers in the Schedule shows that many of the ADs have histories of amendment, which the delegate preserves by remaking them in their latest published form.

The Schedule confines the subject matter to Airworthiness Directives for Teledyne Continental Motors piston engines. That identifies affected parties as those who own, operate, maintain, certify, or otherwise service aircraft equipped with those engines or affected engine components. Practical readers in the target audience should read that as signalling impact on a set of engine-specific maintenance and airworthiness regimes. The Schedule entries name aircraft part types and systems (for example, exhaust valves, oil dip stick retention, piston pins, cylinder heads, crankshafts, fuel pumps, turbochargers, rocker arm shafts, etc.), which shows a broad set of engine-related maintenance points where the ADs will address required inspections, replacements, modifications or retirements.

The instrument itself does not list individual operators, maintenance organisations, certificated maintenance engineers, or parts suppliers by name. It therefore affects anyone whose legal obligations depend on the operative content of an AD listed in the Schedule. Because the instrument revokes and remakes the ADs "in exactly the same form" as the latest published edition, the substantive duties, prohibitions or mandatory inspections contained in those ADs (as they appear in their latest published editions) will determine the day-to-day obligations of affected persons. To determine whether a particular aircraft or component is affected, an operator must consult the attached ADs or the latest published edition of each AD named in the Schedule.

The presence of some entries annotated "CANCELLED" in the Schedule affects who needs to act. If an AD has been cancelled but remains listed in Schedule 1, the instrument nevertheless revokes it and remakes the AD as attached. That may generate uncertainty for operators if a listed AD has been cancelled previously: operators must consult the attached remade instrument and the latest published edition to confirm whether any operative requirement persists. The Schedule also shows ADs with amendment numbers (for example "Amdt 1", "Amdt 2", "Amdt 3", "Amdt 7") indicating a history of change; affected parties need to be aware that the remade AD will reflect the latest published amendments.

Who pays: owners and operators of aircraft fitted with the listed Teledyne Continental components carry the costs of whatever requirements appear in the remade ADs (inspection, replacement, modification, retirement, or other mandated action). Service providers,maintenance organisations and certificated engineers,will also bear administrative and labour costs of compliance and recordkeeping. Suppliers of parts and overhaul services may experience demand changes driven by the AD content. CASA as regulator undertakes the administrative task of revoking and remaking instruments; its costs and recordkeeping burden are borne by the regulator.

Who decides: the delegate of CASA exercised statutory authority under subregulation 39.001(1) to make this instrument. After the remaking, decisions about compliance will be driven by the content of the re-made AD instruments (attached), and by CASA’s administrative processes for publishing and enforcing ADs under the CASR regime.

The instrument’s text sets out the administrative duties of the delegate, not the operational duties of aircraft operators. The delegate’s duties are explicit: (a) to revoke the Airworthiness Directives mentioned in Schedule 1; and (b) to make, as separate instruments, each Airworthiness Directive mentioned in Schedule 1 and attached. Those two clauses are the operative commands of the instrument and identify what the delegate must do under subregulation 39.001(1).

Operational duties and rights of affected persons are not detailed in the body of this instrument. Instead, the instrument remakes each AD "in exactly the same form as appears in the latest published edition of the Directive." Therefore the operative duties, prohibitions, permissible deviations, compliance periods, inspection intervals, parts replacements and reporting obligations that apply to owners, operators and maintainers are contained in the attached ADs or the "latest published edition" which the Note references. To determine precise duties and any administrative rights (for example, applications for alternative methods of compliance, approvals, reporting waivers or appeals) practitioners must consult those attached remade ADs.

The instrument does not itself include provisions that create specific rights of appeal or specify alternative methods of compliance. It also does not prescribe inspection intervals, parts to be replaced, or retirement life limits; those details belong to the remade ADs. The “exactly the same form” wording limits the delegate’s action to administrative re-issuance rather than substantive change; rights and duties therefore track the content of the latest published editions of the ADs.

Recordkeeping duties arise implicit from the restructuring: because ADs have been remade as separate instruments and some prior ADs are annotated "CANCELLED" or show amendment numbers, practitioners should treat the remaking process as potentially changing citation and retrieval paths for ADs. That implies a practical duty to update compliance registers, maintenance control manuals and continuing airworthiness records to reference the remade instrument identifiers and attached AD text.

Finally, the instrument’s silence on penalties or enforcement mechanisms means that those matters, including any rights to procedural fairness or review, will be governed by other provisions in the CASR framework and by the content of the remade ADs themselves. This instrument neither creates nor removes such procedural rights within its own text.

This instrument does not specify any penalties, monetary fines, or enforcement mechanisms within its text. It is an administrative act composed of a revocation provision, a remaking provision, a Schedule listing the ADs affected, and a Note stating the remade ADs mirror the latest published editions. There are no clauses in the instrument that set out sanctions for non‑compliance, nor any procedural enforcement steps. The only statutory citation is the authority under which the delegate acts, subregulation 39.001(1) of CASR 1998.

Because this instrument remakes Airworthiness Directives as separate instruments, enforcement and penalties,if any,will depend on the legal status of those remade ADs and on the broader regulatory framework established elsewhere in CASR 1998 and related legislation. The instrument itself does not reproduce those enforcement regimes, and practitioners must therefore consult the remade ADs and the enabling regulatory framework (CASR and any applicable Civil Aviation Act provisions, not reproduced here) to determine which contraventions attract penalties, which enforcement bodies act, and what processes apply.

The Schedule shows a mix of current ADs and entries annotated "CANCELLED", plus entries with amendment markers. That administrative history can affect enforcement in practice, because it affects which text is current at any moment. The Note purports to remove substantive ambiguity by remaking each AD "in exactly the same form as appears in the latest published edition of the Directive", but the practical effect for enforcement is that regulators and enforcers must rely on the remade instrument and its attachments to determine the content to be enforced. If an operator is cited for non-compliance with an AD, the relevant instrument for proving the obligation will be the remade AD attached to this instrument (or, as the Note suggests, the latest published edition of the Directive).

In short, the instrument itself is silent on penalties and enforcement. Any enforcement consequences for affected persons therefore arise from the AD content, and from the broader CASR enforcement architecture, neither of which are contained in the text of this instrument. Practitioners should therefore ensure they consult the remade AD attachments and the CASR enforcement provisions to determine the concrete penalties and enforcement paths that might apply.

The instrument explicitly situates itself within the Civil Aviation Safety Regulations 1998 regime by invoking subregulation 39.001(1) as the source of its delegated authority. It does not reproduce the broader regulatory provisions, nor does it reference other statutory instruments within its text. The instrument therefore performs a narrow administrative function under CASR 1998: it changes the form in which specified ADs are held and presented by revoking and remaking them as separate instruments.

Because the instrument remakes ADs "in exactly the same form" as the latest published editions, it seeks to preserve substantive interaction with other legal requirements tied to those ADs. Any interaction effects,overlap, precedence, or conflict,between the ADs and other legal obligations (for instance, air operator certificates, maintenance organisation approvals, or continuing airworthiness obligations found elsewhere in CASR 1998) are not resolved within this text; they must be resolved by cross-referencing the remade ADs and the other statutory provisions.

The Schedule’s inclusion of entries annotated "CANCELLED" and entries showing amendment numbers indicates a history of prior regulatory action. The revocation/remaking step interacts with that history by consolidating the latest published form of each AD into separately made instruments. This may change the official citation path and make legal cross-references (for example, in maintenance manuals or certificate conditions) require updating to reference the remade instruments rather than the earlier instrument forms.

The instrument could also interact with publication and instrument-making rules by producing multiple separately issued AD instruments attached to a single revocation/remaking instrument. That administrative configuration may have consequences for how ADs are archived, referred to in legal proceedings, or integrated into compliance systems. Those administrative consequences, however, are procedural and lie outside the text; the instrument itself does not set out those procedural rules.

Because the instrument does not address appeals, review rights, alternative compliance methods, or enforcement procedures, it leaves those interactions to the existing CASR framework and to the content of the remade ADs. Practitioners must therefore treat this instrument as a housekeeping measure within the CASR legislative structure, not as a substantive legal reform that alters how ADs interact with other laws. The only explicit cross-reference within the instrument is to subregulation 39.001(1), which is the legislative anchor for CASA’s power to make ADs.

The instrument records a single administrative act dated 20 December 2004, executed by David Alan Villiers as a delegate of CASA. It does not itself contain a prior amendment history for this instrument because it is a discrete instrument performing revocation and remaking on that date. The Schedule, however, reveals amendment histories for many of the ADs it lists. Several AD entries include amendment markers such as "Amdt 1", "Amdt 2", "Amdt 3", "Amdt 7", and so on. That indicates that many of the listed ADs were previously amended before this revocation/remaking exercise.

The Note in the instrument clarifies 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 language preserves the net effect of the historical amendments: the remade ADs incorporate all prior amendments up to their latest published editions. The purpose of listing amendment numbers in the Schedule appears to be to record the most recent amendment status of each AD at the time of revocation and remaking.

Entries annotated "CANCELLED" in the Schedule indicate that some ADs had already been cancelled prior to this instrument. The inclusion of cancelled ADs in the Schedule suggests the revocation step applies even where an AD had been administratively cancelled, and that the remaking step will re-issue the ADs as separate instruments reflecting their latest published form,which, for cancelled ADs, may replicate their cancelled status or otherwise document their cancellation in the remade form. The instrument does not explain the rationale for including cancelled items in the Schedule, but it does preserve the notation.

There is no subsequent amendment history recorded within this instrument. To trace further amendment history of any remade AD after 20 December 2004 practitioners must consult the remade AD instruments attached to this instrument, and the civil aviation instrument registers or publication repositories that record subsequent amendments. The instrument itself does not set out a process for future amendment; it is a snapshot administrative act that captures the ADs as they existed in their latest published editions on the date of remaking.

The instrument contains no reference to any litigation. It does not mention court proceedings, judicial interpretations, or administrative appeals. There is no record in the text of contested applications, judicial review, or any case law relating to the revocation or remaking action it records.

Because the instrument is a formal administrative act revoking and remaking multiple ADs under delegated authority, the absence of litigation references in the instrument means that any legal challenges or judicial reviews concerning the revocation/remaking process would need to be researched outside this instrument,by consulting case law databases, government litigation registers, or CASA’s administrative records. None of that material is reproduced or referenced in the instrument’s text supplied here.

Practitioners should therefore treat this instrument as having no litigation history recorded within it. If litigation or judicial decisions exist concerning any of the ADs listed in the Schedule, those decisions would be external to this instrument and would need to be located via independent legal research. The instrument’s silence on litigation does not imply the absence of any legal disputes historically concerning the ADs; it only means that the instrument itself does not record, reference, or summarise such disputes.

Several operational and interpretative pitfalls arise from the instrument’s sparse text and the way the Schedule is presented. First, the instrument revokes and remakes ADs but does not reproduce the substantive AD text in the body of the instrument; instead it relies on attached ADs said to be identical to the latest published editions. If a practitioner only has access to the Schedule, they will not know the operative compliance text. The Note’s reliance on "the latest published edition" means that to determine obligations one must obtain either the attached remade ADs or the published edition referred to by the Note. The instrument therefore creates a potential retrieval risk for operators who fail to obtain the attachments.

Second, the Schedule includes many entries annotated "CANCELLED". Revocation of an already cancelled AD, followed by remaking as a separate instrument, can create confusion about legal status. Practitioners must not assume that the annotation means an AD no longer imposes obligations; instead they must check the remade attached instrument to confirm whether cancellation is recorded, superseded or otherwise embodied in the remade form. Failure to check may lead to mistaken assessments of whether a requirement remains in force.

Third, amendment markers in the Schedule highlight that many ADs have amendment histories. The Note's instruction to remake each AD "in exactly the same form as appears in the latest published edition" preserves those amendments, but it also means the operative AD may include a complex amendment history. Practitioners should be careful when citing or complying with ADs to reference the remade instrument and not an older numbered amendment or earlier version.

Fourth, the instrument changes the form of the ADs from whatever they were before into separate attached instruments. That can disrupt citation and cross-referencing in existing compliance documentation, maintenance control manuals, logbooks, and airworthiness records. Operators and maintenance organisations must update their document references; failure to do so could lead to recordkeeping discrepancies even where substantive compliance has been achieved.

Fifth, the instrument itself does not state what happens to transitional compliance dates, previously approved deviations, or alternative methods of compliance that may have been accepted under earlier AD forms. Since the instrument does not address those matters, practitioners must check the remade ADs and any CASA administrative guidance to confirm whether previously granted approvals survive the remaking process.

Finally, because this instrument is an administrative housekeeping exercise, there is a risk that operational personnel overlook it as non-substantive. The Note's assurance that the remade ADs are "exactly the same" can lull organisations into thinking no action is required; but the practical implications for record-keeping, citation, and retrieval mean that administrative updates are needed. Organisations should therefore treat this instrument as requiring coordinated compliance-administration work even where the technical maintenance actions remain unchanged.

The instrument itself instructs the delegate to revoke and remake the listed ADs; it does not spell out compliance steps for operators. Nevertheless the instrument creates discrete practical tasks for affected parties to ensure legal and operational continuity. The actions below flow directly from the instrument’s mechanics as stated in paragraphs (a) and (b) and from the Note that remade ADs equal the latest published editions.

1. Obtain the remade ADs: Acquire the attached Airworthiness Directives that are remade as separate instruments. The instrument relies on attached ADs for the operative content. If the attachments are unavailable from this instrument, obtain the latest published edition of each Directive named in Schedule 1, because the Note says the remade ADs are identical to those editions.

2. Update references: Replace citations in maintenance control manuals, continuing airworthiness records, aircraft logbooks and safety management system registers so they reference the remade AD instrument identifiers and the attached AD text rather than the prior instrument citation. The Schedule shows that many ADs had amendment markers; ensure the reference matches the remade (latest) edition.

3. Confirm cancellation status: For Schedule entries annotated "CANCELLED", confirm in the remade instrument whether the AD is reproduced as cancelled or whether the remade document contains operative text. Do not rely on the Schedule annotation alone.

4. Verify outstanding approvals: If any alternative methods of compliance, deferred compliance approvals, or exemptions had been granted under the ADs in their prior form, confirm whether those approvals remain in force with CASA or require re‑submission under the remade AD instruments. The instrument does not address transitional or grandfathering treatment.

5. Update compliance log and risk registers: Even where substantive technical requirements are unchanged, update compliance logs and risk registers to reference the remade instruments and to note the administrative change date (20 December 2004) so auditors can reconcile previous and current records.

6. Communicate to maintenance staff and suppliers: Notify certificated engineers, maintenance organisations, parts suppliers and overhaul providers that the ADs have been remade as separate instruments and supply copies of the remade ADs so they can align maintenance planning and parts procurement.

7. Retain proof of compliance: Keep copies of the remade ADs with documentary evidence of any inspections, replacements, modifications or retirements carried out under them. Because the instrument changes the form of ADs, records should show both the action taken and the remade instrument under which the action was taken.

8. Seek regulatory clarification where unclear: If the remade AD attachment or the latest published edition is ambiguous (for example in respect of cancellation notations, transitional approvals, or compliance windows), apply to CASA for clarification or review. The instrument provides no internal appeal or clarification mechanism.

9. Monitor for subsequent amendments: The Schedule demonstrates that ADs can carry amendment histories. After remaking, new amendments can be promulgated. Set up monitoring of CASA publications and AD registers to capture any further changes.

10. Legal checks: Where precise legal status is material for a transaction (for example sale, lease, or certification), obtain legal confirmation that the remade instrument is the operative legal instrument and that any prior AD references have been superseded in legal citation terms.

These steps are practical responses to an administrative reshaping of AD instruments. They follow from the instrument’s two operative clauses and the Note that the remade ADs replicate the latest published editions. Because the instrument does not itself specify substantive maintenance requirements, compliance in substance depends on following the remade ADs.
