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, the Civil Aviation Safety Authority (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.
CASA’s predecessor issued AD/PA-31/101 Amendment 3 affecting Piper PA-31 model aircraft in 1983. CASA has decided to amend this AD to improve its clarity. Amendment 4 of this AD will become effective on 31 July 2008. Amendment 4 cancels and replaces Amendment 3.
No consultation with the Australian public has taken place on this AD amendment because the amendment imposes no increase in the regulatory burden. 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 provide a comprehensive legal framework for civil aviation in Australia, ensuring the safety and efficiency of air navigation. Under section 98 of this Act, the Governor-General is empowered to make regulations that serve the interests of aviation safety, delegating this authority to the Civil Aviation Safety Authority (CASA). The Civil Aviation Safety Regulations 1998, established under this Act, allow CASA to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, as outlined in regulation 39.001. These ADs, which are legislative instruments as per the Legislative Instruments Act 2003, are crucial for maintaining the continuing airworthiness of aircraft, aligning with international standards set forth in Annex 8 to the Convention on International Civil Aviation. CASA, as Australia’s national airworthiness authority, is mandated to assess information from the State of Design and, when necessary, issue Australian ADs to enforce the requirements of the State of Design on aircraft registered in Australia.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the authority of the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. This regulatory framework ensures the safety of air navigation and the continuing airworthiness of aircraft registered within Australia, in accordance with the requirements outlined in Annex 8 to the Convention on International Civil Aviation. The State of Design is responsible for the ongoing airworthiness of an aircraft type and must provide necessary information to the State of Registry, which in turn is responsible for implementing the requisite measures to maintain the aircraft's airworthiness. CASA, as Australia's national airworthiness authority, must assess the information provided by the State of Design and, if appropriate, issue an Australian AD to enforce the mandated requirements. The legislative instruments, such as ADs, are considered disallowable instruments under the Acts Interpretation Act 1901 and are treated as legislative instruments under the Legislative Instruments Act 2003. The issuance of AD Amendment 4 for Piper PA-31 model aircraft, effective from 31 July 2008, exemplifies CASA's commitment to improving regulatory clarity without increasing the regulatory burden.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 lay out a framework for ensuring the safety and airworthiness of aircraft within Australia. Under section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to create regulations that contribute to the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These ADs are a form of disallowable instrument under section 46A of the Acts Interpretation Act 1901, meaning they are subject to scrutiny and potential disallowance by Parliament.
The obligations placed on CASA under this regulation are significant. CASA must ensure that any airworthiness directive issued by the State of Design for a type of aircraft registered in Australia is assessed and, if necessary, adapted into an Australian AD. This process ensures that Australian aircraft meet international safety standards as stipulated in Annex 8 to the Convention on International Civil Aviation. The State of Registry, which in this context is Australia, has a responsibility to ensure the continuing airworthiness of its aircraft. This involves developing or adopting requirements that align with the ADs issued by the State of Design. CASA, acting on behalf of Australia, plays a crucial role in this process by implementing these requirements through Australian ADs.
Failure to comply with an AD can lead to serious consequences. Non-compliance with an airworthiness directive may result in the aircraft being grounded, preventing it from flying until the required actions are taken. This not only affects the operator of the aircraft but also poses significant safety risks. Under the Civil Aviation Act 1988, individuals or entities that violate these regulations may face penalties. While the exact penalties are not specified in the provided text, such violations typically include fines and potential criminal charges, reflecting the critical nature of air safety regulations.
