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 35/17 affecting all model Beechcraft 35 aircraft with serial numbers prior to D4215. CASA has assessed this AD and as a result has cancelled Australian AD/BEECH 35/17. The cancellation will become effective on 8 May 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 Acting Manager, Systems and New Technologies 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 Parliament of Australia, serves as the foundational statute for the regulation and oversight of civil aviation within the country. The 1988 Act was introduced to address the need for a comprehensive legal framework that would ensure the safety, efficiency, and orderly development of civil aviation. It grants the Governor-General the authority to create regulations aimed at enhancing the safety of air navigation, a crucial aspect of the aviation industry. The Civil Aviation Safety Regulations 1998, made under the authority of the Act, further detail the regulatory requirements for ensuring the airworthiness of aircraft. Regulation 39.001 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives, which are legislative instruments that become enforceable upon disallowance under the Acts Interpretation Act 1901. CASA, as the national airworthiness authority, is tasked with issuing these directives to mandate safety requirements derived from international standards and national assessments.
Scope and Application
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, thereby ensuring adherence to safety standards mandated by the Civil Aviation Act 1988. These ADs are legislative instruments, as outlined in subregulation 39.001(5) and further clarified by the Legislative Instruments Act 2003. The ADs are essential for maintaining the continuing airworthiness of aircraft, aligning with the obligations of the State of Design and State of Registry under Annex 8 to the Convention on International Civil Aviation. CASA, acting as Australia’s national airworthiness authority, is responsible for assessing and issuing such directives to ensure compliance with international standards, thereby safeguarding the safety of air navigation within Australia.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together provide the framework for ensuring the safety of air navigation in Australia. Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations necessary for the safety of air navigation, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 enables the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. An AD is a legislative instrument under section 6 of the Legislative Instruments Act 2003 and is subject to disallowance under section 46A of the Acts Interpretation Act 1901.
The obligations of the State of Design under Annex 8 to the Convention on International Civil Aviation are crucial in this context. The State of Design has the overall responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to the appropriate States of Registry to ensure the aircraft’s continued safe operation. In Australia, CASA, as the national airworthiness authority, is responsible for assessing the information provided by the State of Design and, if appropriate, issuing an Australian AD to mandate the required safety measures. Similarly, the State of Registry is responsible for developing or adopting requirements to ensure the continuing airworthiness of aircraft registered within its territory.
Under the Civil Aviation Safety Regulations 1998, CASA has issued various ADs to address safety concerns, such as AD/BEECH 35/17 for Beechcraft 35 aircraft with serial numbers prior to D4215. However, CASA has subsequently cancelled Australian AD/BEECH 35/17 because the unsafe condition it was intended to address no longer exists. The cancellation of this AD took place on 8 May 2008, and no replacement AD was required. Due to Australia’s obligations under the Convention on International Civil Aviation, CASA did not consult the Australian public on this cancellation, and the Office of Best Practice Regulation determined that ADs do not require a Regulatory Impact Statement. The AD was made by the Acting Manager, Systems and New Technologies in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A(2) of the Act.
Failure to comply with ADs can result in serious safety risks and potential legal consequences. Under section 22 of the Civil Aviation Act 1988, any person who contravenes an AD can be fined up to $126,000 for an individual and $630,000 for a body corporate, in addition to potential imprisonment for up to two years. Furthermore, CASA may impose further penalties or sanctions, including the suspension or revocation of an aircraft's certificate of airworthiness, which can prevent the aircraft from operating legally. The seriousness of these penalties underscores the importance of adhering to ADs to maintain the highest standards of aviation safety.
