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.
The Civil Aviation Safety Authority or its predecessors issued AD/BEECH 90/88 affecting Beechcraft 90 and 65-90 model aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/BEECH 90/88. The cancellation will become effective on 31 July 2008. No replacement AD is required, as the unsafe condition no longer exists.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, no consultation with the Australian public has taken place on this AD cancellation. 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, Airframe and Structures, 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, serves to ensure the safety and efficiency of civil aviation within Australia. This legislation provides the legal framework for the Civil Aviation Safety Regulations 1998, under which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) to maintain and ensure the continuing airworthiness of aircraft. The ADs are instrumental in fulfilling Australia's obligations under Annex 8 of the Convention on International Civil Aviation, which mandates that the State of Design provides essential information for the continuing airworthiness of aircraft types, and that the State of Registry enforces these requirements. The Act aims to uphold the highest safety standards in civil aviation, aligning with international norms and ensuring the integrity of aircraft operations within Australia.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together provide the legislative framework for the issuance and management of airworthiness directives (ADs) in Australia. The Act applies to the Governor-General, who has the power to make regulations for the purposes of the Act and in the interests of the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically empowers the Civil Aviation Safety Authority (CASA) to issue ADs for types of aircraft or aeronautical products. These ADs are considered legislative instruments and are subject to disallowance under the Acts Interpretation Act 1901. CASA, as Australia's national airworthiness authority, is responsible for assessing ADs issued by the State of Design and issuing Australian ADs when necessary to ensure the continuing airworthiness of aircraft on the Australian Register. The geographic reach of these regulations is national, with CASA acting in accordance with international obligations under the Convention on International Civil Aviation, particularly Annex 8, which places responsibility for continuing airworthiness on the State of Design and State of Registry. The cancellation of a specific AD, such as AD/BEECH 90/88 for Beechcraft 90 and 65-90 model aircraft, reflects the dynamic nature of air safety regulations and the commitment to international standards, with no public consultation required due to these international obligations.
Key Provisions
The Civil Aviation Act 1988, particularly under section 98, empowers the Governor-General to enact regulations that safeguard air navigation safety. Complementing this, regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific aircraft types or aeronautical products. These ADs are formal instruments under subregulation 39.001(5) and the Acts Interpretation Act 1901, thereby making them subject to disallowance and legislative scrutiny as per the Legislative Instruments Act 2003. This legislative framework ensures that ADs, as a primary means of maintaining airworthiness, align with international standards under Annex 8 of the Convention on International Civil Aviation, where the State of Design holds primary responsibility for aircraft type airworthiness, and States of Registry must enforce these standards domestically.
The obligations under this legislation require CASA, as Australia's national airworthiness authority, to meticulously evaluate ADs issued by the State of Design concerning aircraft registered in Australia. When an AD is issued by the State of Design, CASA must review the information and, if necessary, issue an Australian AD to enforce the safety requirements. For instance, CASA issued AD/BEECH 90/88 concerning Beechcraft 90 and 65-90 model aircraft. After careful assessment, CASA cancelled AD/BEECH 90/88, effective from 31 July 2008, due to the resolution of the unsafe condition. This cancellation signifies that no further action is required as the safety issue has been addressed.
Under the Civil Aviation Safety Regulations 1998, CASA's role includes ensuring that any ADs issued are in line with international obligations and are appropriately communicated to stakeholders. This includes verifying that all necessary safety measures are implemented by the aircraft operators. Any failure to comply with the mandated ADs could lead to severe consequences, as CASA has the authority to enforce these regulations strictly. The regulatory framework underscores the importance of adhering to airworthiness directives to maintain the highest safety standards in civil aviation.
In terms of consequences, breaches of the Civil Aviation Safety Regulations 1998 can result in both civil and criminal penalties. Under section 84A(2) of the Civil Aviation Act 1988, any non-compliance with ADs could be considered a serious breach of safety regulations, potentially leading to significant fines and other sanctions. The specific penalties are determined based on the severity of the breach and the impact on aviation safety. The regulatory impact of these breaches is significant, as they directly affect the safety and reliability of air travel, a critical aspect of public transport infrastructure in Australia.
