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 CAA of New Zealand has issued AD DCA/750XL/3A affecting Pacific Aerospace Corporation 750XL model aircraft. New Zealand is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/750XL/3 Amendment 1, which will become effective on 14 February 2008. This AD cancels and replaces the previous issue.
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 Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the 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, is foundational legislation governing civil aviation in Australia. It provides the legal framework for ensuring the safety and efficiency of civil aviation operations, including the issuance of airworthiness directives to maintain the continuing airworthiness of aircraft. The Civil Aviation Safety Regulations 1998 further detail the regulatory requirements under the Act. One significant aspect of this legislation is the authority granted to the Civil Aviation Safety Authority (CASA) to issue airworthiness directives in accordance with Annex 8 to the Convention on International Civil Aviation. This process ensures that Australian aircraft meet international safety standards and aligns with the obligations of the State of Registry and the State of Design. The objective of these regulations is to protect public safety and maintain high standards of airworthiness, as mandated by international conventions and Australian law.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products, ensuring the ongoing airworthiness of aircraft registered in Australia. This regulatory framework is integral to maintaining the safety standards of civil aviation in Australia, aligning with international obligations under the Convention on International Civil Aviation. The ADs serve as a means for the State of Registry, in this case CASA, to implement the continuing airworthiness requirements mandated by the State of Design, such as the CAA of New Zealand for the Pacific Aerospace Corporation 750XL model aircraft. The ADs issued by CASA are legislative instruments subject to disallowance and are made in accordance with the provisions of the Legislative Instruments Act 2003. Given the international nature of airworthiness directives and their focus on safety, these instruments are typically issued without public consultation or a Regulatory Impact Statement. The application of these directives is geographically bound to Australia and its registered aircraft, ensuring compliance with both national and international aviation safety standards.
Key Provisions
The Civil Aviation Act 1988, specifically under section 98, empowers the Governor-General to create regulations for the safety of air navigation. These regulations are designed to ensure the safety and efficiency of air travel within Australian territory and beyond. Under regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) is authorised to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives are legal instruments that mandate actions to ensure the continued safety of aircraft in operation, as outlined in subregulation 39.001(5). The ADs are considered disallowable instruments as per section 46A of the Acts Interpretation Act 1901, and they are legislative instruments under the Legislative Instruments Act 2003.
The obligations imposed by the ADs on the relevant parties, such as aircraft manufacturers, operators, and owners, are significant. The State of Design, which is the country where the aircraft was designed, is responsible for the continuing airworthiness of the aircraft type. This includes providing necessary information to States of Registry to ensure compliance with safety standards. The State of Registry, which is the country where the aircraft is registered, must adopt or develop requirements to ensure the continuing airworthiness of the aircraft. When a State of Design issues an AD, CASA, as Australia’s national airworthiness authority, must assess the information and issue an Australian AD if appropriate. This ensures that Australian aircraft comply with international safety standards and regulations.
The ADs carry substantial consequences for non-compliance. Failure to adhere to the requirements outlined in an AD can result in serious safety risks and potential legal consequences. Under the Civil Aviation Act 1988, non-compliance with an airworthiness directive can lead to enforcement actions, including fines and potential criminal charges for serious breaches. The maximum penalties for these offences are specified in the Act, reflecting the importance of compliance with airworthiness standards. CASA has the authority to take action against non-compliant aircraft and operators, which can include grounding aircraft until the required actions are taken. The stringent enforcement of these directives is crucial to maintaining high safety standards in the aviation industry.
