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 90/3 Amendment 1, affecting Beech 90 model aircraft in 1972. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 3 July 2008. No replacement AD is required, as normal maintenance practices now address the unsafe condition.
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, enacted by the Australian Parliament, addresses various aspects of civil aviation within Australia, focusing primarily on ensuring the safety of air navigation and the continuing airworthiness of aircraft. This Act empowers the Governor-General to make regulations that align with the Act's objectives, particularly concerning the safety of air navigation. Under the authority granted by the Civil Aviation Act 1988, the Civil Aviation Safety Regulations 1998 permit the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives serve as a crucial mechanism for maintaining the safety standards required by the Convention on International Civil Aviation, ensuring that aircraft continue to meet necessary safety standards throughout their operational life. The policy objective behind these regulations is to uphold the highest standards of aviation safety, aligning with both national and international requirements.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 govern the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA), Australia's national airworthiness authority. These regulations empower CASA to issue ADs for specific types of aircraft or aeronautical products under regulation 39.001, aiming to ensure the safety of air navigation. ADs, as disallowable instruments under the Acts Interpretation Act 1901 and legislative instruments under the Legislative Instruments Act 2003, are essential for maintaining the continuing airworthiness of aircraft. The State of Design, typically the country where the aircraft was designed, has the primary responsibility for ensuring the continuing airworthiness of an aircraft type, while the State of Registry, in this case, Australia, must enforce and adopt the requirements to maintain this airworthiness. CASA must review and potentially issue Australian ADs when a State of Design issues an AD for aircraft registered in Australia. CASA issued AD/BEECH 90/3 Amendment 1 for Beech 90 model aircraft in 1972, which has now been cancelled due to the condition it addressed being covered by normal maintenance practices, effective from 3 July 2008. The decision to cancel the AD was made without public consultation as it reduces regulatory burden, and no Regulatory Impact Statement was required. The cancellation was authorised by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A(2) of the Act.
Key Provisions
The main operative sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 concern the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations for the safety of air navigation, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically allows CASA to issue ADs for types of aircraft or aeronautical products. These ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and are legislative instruments in accordance with section 6 of the Legislative Instruments Act 2003. Such ADs serve to ensure the continuing airworthiness of aircraft as mandated by Annex 8 to the Convention on International Civil Aviation, where the State of Design has the overarching responsibility for the continuing airworthiness of an aircraft type.
The obligations and requirements imposed by these provisions on parties such as CASA, States of Design, and States of Registry are significant. CASA, as Australia’s national airworthiness authority, must review and act on ADs issued by the State of Design. When a State of Design issues an AD, CASA must assess the information and, if necessary, issue an Australian AD to mandate the requirements. This process ensures that the continuing airworthiness of aircraft on the Australian Register is maintained according to internationally recognised standards. The State of Registry of an individual aircraft is also responsible for ensuring the continuing airworthiness of that aircraft, either by developing or adopting requirements to meet these standards. This regulatory framework aims to ensure that aircraft in Australian airspace meet safety standards set forth by ICAO.
Failure to comply with the ADs or the obligations set forth in the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can result in significant legal consequences. CASA, as the enforcing body, can impose penalties and sanctions for non-compliance. While specific penalties are not detailed in the provided text, it is clear that non-compliance could result in regulatory action against the operators or manufacturers of the aircraft. Such actions could include fines, suspension of operations, or other enforcement measures designed to ensure adherence to airworthiness standards. The regulatory framework is designed to protect public safety by ensuring that all aircraft meet stringent safety criteria.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a comprehensive regulatory regime for the issuance and enforcement of airworthiness directives. CASA has the authority to issue these directives, which are crucial for maintaining the safety and airworthiness of aircraft. The obligations on CASA, States of Design, and States of Registry are clear, with a focus on ensuring that aircraft meet international safety standards. Non-compliance with these regulations can result in significant penalties, reinforcing the importance of adhering to the established safety protocols.
