CIVIL AVIATION ACT 1988
CIVIL AVIATION 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 New Zealand CAA has issued AD DCA/750XL/4 affecting Pacific Aerospace 750XL model aircraft. New Zealand is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/750XL/4, which will become effective on 7 July 2005.
As this AD is issued because of Australia’s obligations under Convention on International Civil Aviation, and because it is issued in response to an AD raised by the relevant State of Design, no consultation of the Australian public has taken place on this AD. The Office of Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Section Head - Airframes, Airworthiness Standards Branch, Standards Division, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to regulate civil aviation in Australia, ensuring the safety and efficiency of air navigation. Under this Act, the Civil Aviation Safety Regulations 1998 were created, which empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. These directives are critical for maintaining the continuing airworthiness of aircraft and are issued in accordance with international standards set by the International Civil Aviation Organization (ICAO). The legislation underscores CASA's responsibility to evaluate and respond to ADs issued by other states, such as New Zealand, which has designated Pacific Aerospace 750XL aircraft as its State of Design. CASA's issuance of Australian AD/750XL/4 on 7 July 2005 exemplifies this responsibility, reflecting Australia's commitment to international civil aviation obligations and safety standards.
Scope and Application
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, governs the issuance of airworthiness directives (ADs) in Australia. These regulations empower the Civil Aviation Safety Authority (CASA) to issue ADs for specified types of aircraft or aeronautical products under regulation 39.001. ADs are legislative instruments and serve to ensure the continuing airworthiness of aircraft by mandating safety requirements. The application of these directives extends to all aircraft registered in Australia, and CASA, as the national airworthiness authority, must respond to ADs issued by the State of Design, such as the New Zealand Civil Aviation Authority for the Pacific Aerospace 750XL model aircraft. The ADs issued by CASA, like AD/750XL/4, become effective as mandated and are in response to international obligations under the Convention on International Civil Aviation. The process does not require public consultation, and ADs are not subject to a Regulatory Impact Statement. The ADs are formulated by CASA officials, ensuring compliance with international standards and Australian aviation safety regulations.
Key Provisions
The Civil Aviation Act 1988, and specifically section 98, empowers the Governor-General to create regulations that ensure the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 permits the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. An AD is considered a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and is treated as a legislative instrument in accordance with section 6 of the Legislative Instruments Act 2003.
The obligations imposed by this legislation on the parties involved primarily concern the maintenance of airworthiness standards and the dissemination of relevant safety information. The State of Design, which in this context is New Zealand for the Pacific Aerospace 750XL model aircraft, bears the responsibility for the continuing airworthiness of the aircraft type, including the provision of necessary information to the State of Registry. For Australia, CASA, as the national airworthiness authority, must assess the information provided by the State of Design and, if deemed appropriate, issue an Australian AD to enforce the requirements set by the State of Design. This ensures that Australian aircraft meet the continuing airworthiness standards as per international agreements.
Failure to comply with an airworthiness directive can result in severe consequences. Under the Civil Aviation Act 1988, violations of ADs can lead to civil penalties. The specific penalties are not detailed in the provided text, but typically, they can include fines or other regulatory actions that enforce compliance with safety regulations. Additionally, the failure to adhere to these directives can result in criminal charges, especially if the non-compliance leads to accidents or incidents that endanger public safety.
In summary, the key provisions of this legislation involve the issuance and enforcement of airworthiness directives by CASA, in accordance with international agreements and national safety standards. The obligations on CASA, the State of Design, and the State of Registry are centered around ensuring that all aircraft meet required safety standards. Breaches of these directives can result in both civil and criminal penalties, with the primary aim being to maintain the highest safety standards in air navigation.
