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/CESSNA 310/22 Amdt 1affecting Cessna 310 aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/CESSNA 310/22 Amdt 1. 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 Australian Parliament, governs the regulation of civil aviation within Australia and seeks to ensure the safety of air navigation. Under section 98 of this Act, the Governor-General has the authority to make regulations for the purposes of the Act and in the interests of air navigation safety. One such regulation is regulation 39.001 of the Civil Aviation Safety Regulations 1998, which empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These ADs are considered legislative instruments and serve as a primary means of ensuring the continuing airworthiness of aircraft types, aligning with Australia's obligations under the Convention on International Civil Aviation. The issuance and cancellation of these directives are integral to maintaining safety standards in Australian aviation, with CASA acting on behalf of the national airworthiness authority to implement and manage these directives effectively.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, governs the regulation of airworthiness directives (ADs) within Australia. These regulations apply to all aircraft registered in Australia and are designed to ensure the continuing airworthiness of these aircraft. The Civil Aviation Safety Authority (CASA) has the authority to issue ADs under regulation 39.001, and these directives are considered legislative instruments under the Legislative Instruments Act 2003. The Act and its regulations extend to all aircraft within Australian jurisdiction, ensuring compliance with international standards set by the Convention on International Civil Aviation. Notably, the State of Registry, which in Australia is CASA, is responsible for implementing and enforcing ADs to maintain safety standards. The scope of these regulations is not limited to domestic operations but aligns with international obligations, ensuring uniformity in safety practices across the industry.
Key Provisions
The Civil Aviation Act 1988, particularly section 98, empowers the Governor-General to establish regulations aimed at ensuring the safety of air navigation. These regulations are designed to provide a legal framework for maintaining the safety standards necessary for aviation operations in Australia. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 further specifies that the Civil Aviation Safety Authority (CASA) has the authority to issue airworthiness directives (ADs) for various types of aircraft or aeronautical products. An AD is defined under subregulation 39.001(5) as a disallowable instrument, which means it can be annulled by a resolution of either House of Parliament. This regulatory instrument is subject to the scrutiny and requirements outlined in the Legislative Instruments Act 2003.
The obligations imposed by these provisions include the responsibility of the State of Design to ensure the continuing airworthiness of an aircraft type, as outlined in Annex 8 to the Convention on International Civil Aviation. This responsibility extends to providing all necessary information to the States of Registry to maintain the safety standards of the aircraft. For Australian registered aircraft, the State of Registry, in this case CASA, must develop or adopt requirements to guarantee the continuing airworthiness of those aircraft. When an AD is issued by the State of Design for a type of aircraft registered in Australia, CASA must assess this directive and, if deemed necessary, issue a corresponding Australian AD to enforce the required safety measures.
Non-compliance with the provisions of the ADs can result in significant consequences. Although the specific offences and penalties are not detailed within the text, it is implied that failure to adhere to the mandated safety requirements could lead to safety risks, potential accidents, and legal liabilities. Given that ADs are critical for ensuring the safety and airworthiness of aircraft, any breach of these regulations could result in severe civil or criminal penalties, reflecting the high stakes involved in aviation safety. The precise penalties would be aligned with the broader legal framework governing aviation safety in Australia, but they may include fines, enforcement actions, or other regulatory sanctions.
