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/PA-18/10 affecting Piper PA-18 aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/PA-18/10. The cancellation will become effective on 5 June 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, 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 was enacted to establish a legislative framework for the regulation of civil aviation in Australia, ensuring safety and efficiency within the industry. In the interest of maintaining the safety of air navigation, the Governor-General has the authority to make regulations under section 98 of the Act, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) as per regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs are legislative instruments that are subject to disallowance and are issued to address continuing airworthiness issues for aircraft types, in accordance with Annex 8 to the Convention on International Civil Aviation. The State of Design holds primary responsibility for the airworthiness of aircraft types, and ADs are the primary means of communication for ensuring continuing airworthiness among states. CASA, as Australia's national airworthiness authority, is tasked with assessing international ADs and issuing corresponding Australian ADs as necessary. In this instance, CASA has cancelled Australian AD/PA-18/10 for Piper PA-18 aircraft, effective 5 June 2008, due to the resolution of the unsafe condition, without the need for a replacement AD.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together establish the framework under which airworthiness directives (ADs) are issued and managed within Australia. These ADs apply to persons or entities operating aircraft or aeronautical products in Australia, and cover a broad range of conduct and transactions related to ensuring the continuing airworthiness of these items. The ADs issued by the Civil Aviation Safety Authority (CASA) are intended to mandate compliance with airworthiness standards, ensuring that aircraft remain safe for operation. Geographically, the ADs apply nationally within Australia, with CASA acting as the national airworthiness authority responsible for the implementation and oversight of these directives. The authority to issue ADs extends to all types of aircraft and aeronautical products registered in Australia. Additionally, the ADs are crafted to align with international standards, particularly those outlined in Annex 8 to the Convention on International Civil Aviation, which pertains to the continuing airworthiness of aircraft. The ADs can be amended or cancelled by CASA based on safety assessments and international obligations, without the need for public consultation or regulatory impact statements. This legislative framework allows CASA to effectively manage air safety through targeted regulatory interventions.
Key Provisions
The Civil Aviation Act 1988, through section 98, empowers the Governor-General to enact regulations conducive to air navigation safety. Within the framework of this authority, regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are intended to ensure that aircraft remain airworthy throughout their operational life, aligning with the obligations of the State of Design and State of Registry as outlined in Annex 8 to the Convention on International Civil Aviation.
The obligations imposed by these regulations are significant. The State of Design, which is responsible for the design and maintenance of an aircraft type, must provide all necessary information to ensure the continuing airworthiness of that type. This includes issuing ADs, which are critical for communicating required safety measures. On the other hand, the State of Registry, which oversees the individual aircraft, must develop or adopt requirements to maintain the airworthiness of aircraft within its jurisdiction. In Australia, CASA is responsible for assessing ADs issued by other countries and determining whether to issue corresponding Australian ADs. This ensures that Australian-registered aircraft comply with international safety standards.
Failure to comply with the requirements set out in an AD can lead to serious consequences. Section 84A of the Civil Aviation Act 1988 allows for civil penalties for non-compliance, which can include fines of up to $105,000 for individuals and $525,000 for corporations. Additionally, continued operation of an aircraft that does not meet the AD requirements can result in enforcement actions, including grounding of the aircraft. In some cases, continued non-compliance may also lead to criminal charges, with potential imprisonment for those responsible for ensuring compliance. The severity of these penalties underscores the importance of adhering to ADs to maintain the highest standards of aviation safety.
