CIVIL AVIATION ACT 1988
CIVIL AVIATION SAFETY REGULATIONS 1998
ISSUE OF AIRWORTHINESS DIRECTIVE
Under section 98 of the Civil Aviation Act 1988, the Governor-General may make regulations for the purposes of the Act and in the interests of the safety of air navigation. Under regulation 39.001 of the Civil Aviation Safety Regulations 1998, CASA may issue airworthiness directives (ADs) for kinds of aircraft or aeronautical products. Subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998 provides that an AD is a disallowable instrument for the purposes of section 46A of the Acts Interpretation Act 1901. Therefore, in accordance with section 6 of the Legislative Instruments Act 2003, an AD is a legislative 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 ICAO 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. When a State of Design issues an AD against a type of aircraft on the Australian Register, CASA, as Australia’s national airworthiness authority, must assess that information and, if appropriate, issue an Australian AD to mandate the requirements of the State of Design.
CASA issued AD/BEECH 33/1, affecting Beech 33 and 35-33 model aircraft in 1960. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 10 April 2008. No replacement AD is required, as the original unsafe condition no longer exists.
No consultation with the Australian public has taken place on this AD cancellation, because the cancellation results in a reduction of the regulatory burden. The Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide for the regulation of civil aviation and to promote safe and efficient air navigation. The Act empowers the Governor-General to make regulations necessary for the safety of air navigation, with regulation 39.001 of the Civil Aviation Safety Regulations 1998 allowing the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for kinds of aircraft or aeronautical products. This process ensures that aircraft meet safety standards and facilitates international cooperation under Annex 8 to the Convention on International Civil Aviation. The objective is to maintain the continuing airworthiness of aircraft, with CASA, as Australia's national airworthiness authority, playing a crucial role in enforcing these standards. The authority to issue and cancel ADs, such as the recent cancellation of AD/BEECH 33/1, is exercised by CASA in accordance with the provisions of the Civil Aviation Act 1988, demonstrating a commitment to safety and regulatory efficiency.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. This legislation applies to all aircraft registered in Australia and, by extension, to the operators of these aircraft and any associated aeronautical products. The geographic reach of this legislation is national, applying across all states and territories within Australia, in alignment with the overarching obligations under Annex 8 to the Convention on International Civil Aviation. While the Act and its regulations provide a comprehensive framework for ensuring the safety and airworthiness of aircraft, certain exclusions or exemptions are not explicitly detailed within the text. However, the authority to issue ADs is subject to the legislative processes outlined in the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003, thereby ensuring that such directives are duly recognised as legislative instruments. The application and scope of these ADs can also be extended or restricted through subordinate instruments as deemed necessary by CASA.
Key Provisions
The Civil Aviation Act 1988, particularly section 98, empowers the Governor-General to enact regulations for the safety of air navigation. Under this authority, regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. Subregulation 39.001(5) further clarifies that an AD is a disallowable instrument, meaning it can be disallowed by either house of Parliament, and is considered a legislative instrument as per section 6 of the Legislative Instruments Act 2003. This regulatory framework ensures that ADs are formally recognised and can be subject to parliamentary scrutiny.
The obligations under this Act and its associated regulations are multi-faceted. The State of Design, which refers to the country where the aircraft was designed, has the primary responsibility for ensuring the continuing airworthiness of an aircraft type. This involves providing necessary information to States of Registry, which are responsible for the individual aircraft within their jurisdiction. When an AD is issued by a State of Design, CASA must assess this information and, if deemed necessary, issue a corresponding Australian AD to enforce the requirements. This process ensures that safety standards are maintained across all aircraft registered in Australia, aligning with the provisions of Annex 8 to the Convention on International Civil Aviation.
In terms of regulatory consequences, the Civil Aviation Safety Regulations 1998 establish the framework within which ADs operate. Failure to comply with an AD can lead to severe consequences, including potential penalties for non-compliance with airworthiness requirements. While specific penalties are not detailed in the provided text, general aviation regulations often include fines and potential grounding of non-compliant aircraft. Additionally, under the Acts Interpretation Act 1901, disallowance of an AD by either house of Parliament can negate its legal effect, further underscoring the importance of adherence to these directives.
The Civil Aviation (Airworthiness) Regulations 1998 also address the issuance and cancellation of ADs. For instance, CASA issued AD/BEECH 33/1 in 1960, affecting Beech 33 and 35-33 model aircraft. After a review, CASA decided to cancel this AD, effective from 10 April 2008, as the original unsafe condition no longer existed. This cancellation was not subject to public consultation due to its nature of reducing regulatory burden, and it was determined that no Regulatory Impact Statement was required. The AD was made by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A(2) of the Civil Aviation Act 1988, ensuring the process was carried out by authorised personnel.
