Explanatory Statement
Civil Aviation Safety Regulations 1998
CASA ADCX 001/25 — Repeal of Airworthiness Directives AD/TB10/31, AD/TB20/37 and AD/TB 200/4 Instrument 2025
Legislation
Under section 98 of the Civil Aviation Act 1988 (the Act), the Governor-General may make regulations for the purpose of carrying out and giving effect to the provisions of the Convention on International Civil Aviation relating to safety, amongst other things. Under regulation 39.001 of the Civil Aviation Safety Regulations 1998 (CASR), the Civil Aviation Safety Authority (CASA) may issue an airworthiness directive (AD) for a kind of aircraft or aeronautical product. Under subsections 98 (5B) and (5BA) of the Act, an AD is a legislative instrument unless it is expressed to apply in relation to a particular person, a particular aircraft or a particular aeronautical product.
Under subsection 33 (3) of the Acts Interpretation Act 1901, where an Act confers a power to make, grant or issue any instrument of a legislative or administrative character (including rules, regulations or by-laws), the power shall be construed as including a power exercisable in the like manner and subject to the like conditions (if any) to repeal, rescind, revoke, amend, or vary any such instrument.
Under Annex 8 to the Convention on International Civil Aviation, the State of Design has overall responsibility for continuing airworthiness of an aircraft type and must provide any information necessary to ensure the continuing airworthiness of a type to appropriate States of Registry. ADs (and their equivalents) are the most common form of continuing airworthiness information and are issued by most International Civil Aviation Organization Contracting States.
The State of Registry of an individual aircraft is responsible for its continuing airworthiness. Under Annex 8, the State of Registry must develop or adopt requirements to ensure the continuing airworthiness of aircraft. Regulation 39.001A of CASR, defines “airworthiness directive” to include foreign State of Design ADs issued on or after 1 October 2009. Accordingly, when a foreign State of Design issues an AD for a type of aircraft on the Australian Register, that AD applies to Australian aircraft. However, CASA may grant an exclusion from the AD or approve an acceptable means of compliance other than that set out in the AD.
Background
The French Civil Aviation Authority issued French AD F-2001-002(A) in January 2001 and CASA issued AD/TB10/31, AD/TB20/37 and AD/TB 200/4 to mandate the requirement of this AD for Australian operators.
The European Aviation Safety Authority (EASA) has revoked French AD F-2001-002(A) by issuing AD 2025-0160 which is automatically adopted by CASA under Part 39 of CASR. This foreign AD applies to Daher Aerospace (Socata / Aerospatiale) TB 9, TB 10, TB 20, TB 21, and TB 200 Aeroplanes.
Repeal
This instrument repeals 3 Australian airworthiness directives.
AD/TB10/31- Rudder Bearings (AD/TB10/31) is repealed because the requirements of AD/TB10/31 have been superseded by EASA AD 2025-0160 issued on 25 July 2025 with an effective date of 8 August 2025.
This instrument also repeals AD/TB20/37 - Rudder Bearings (AD/TB20/37), because the requirements of AD/TB20/37 have been superseded by EASA AD 2025-0160 issued on 25 July 2025 with an effective date of 8 August 2025.
This instrument also repeals AD/TB 200/4 - Rudder Bearings (AD/TB 200/4), because the requirements of AD/TB 200/4 have been superseded by EASA AD 2025-0160 issued on 25 July 2025 with an effective date of 8 August 2025.
The ADs will be repealed on 12 September 2025.
Consultation
No public or other consultation has taken place on the repeal of AD/TB10/31, AD/TB20/37 and AD/TB 200/4 because the requirements of ADs AD/TB10/31, AD/TB20/37 and AD/TB 200/4 have been superseded by EASA AD 2025-0160, which must be complied with from its effective date because it is a foreign State of Design AD. For this reason, it is CASA’s view that it is not necessary or appropriate to undertake any consultation under section 17 of the Legislation Act 2003 (LA).
Office of Impact Analysis (OIA)
An Impact Analysis (IA) is not required because ADs are covered by a carve out by the Office of Impact Analysis under which an IA is not required for Australian or foreign airworthiness directives (OIA23-06244).
Sunsetting
As the instrument relates to aviation safety and is made under CASR, Part 4 of Chapter 3 of the LA (the sunsetting provisions) does not apply to the instrument (as per item 15 of the table in section 12 of the Legislation (Exemptions and Other Matters) Regulation 2015). However, this instrument will be repealed in accordance with section 48A of the LA, which will occur before the sunsetting provisions would have repealed the instrument if they had applied. Therefore, the exemption from sunsetting does not affect parliamentary oversight of this instrument.

The repealed ADs relate to inspection and rectification or maintenance of specified aircraft or aeronautical products.
