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.
CASA issued AD/PA-32/77 affecting Piper PA-32 series aircraft in 1991. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 17 January 2008. No replacement AD is required, as the original unsafe condition has long ceased to exist.
No consultation with the Australian public has taken place on this AD cancellation, because the cancellation results in a reduction of 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, Airframes 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 legislative framework for civil aviation in Australia, ensuring safety and efficiency in air navigation. The Act empowers the Governor-General to make regulations in the interest of safety, which includes the issuance of airworthiness directives by the Civil Aviation Safety Authority (CASA). This authority is exercised under regulation 39.001 of the Civil Aviation Safety Regulations 1998, where CASA can issue directives for specific kinds of aircraft or aeronautical products. The cancellation of the airworthiness directive AD/PA-32/77, which was issued in 1991 and affects Piper PA-32 series aircraft, exemplifies the Act’s application in managing aviation safety. CASA, as Australia’s national airworthiness authority, has determined that the directive can be cancelled as the original safety concerns no longer exist, thus reducing regulatory burden. This action was taken under the authority granted by the Act, ensuring that the safety standards continue to be upheld without unnecessary regulatory constraints.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, provides the legislative framework for the issuance of airworthiness directives (ADs) in Australia. Specifically, regulation 39.001 allows the Civil Aviation Safety Authority (CASA) to issue ADs for certain kinds of aircraft or aeronautical products, thereby ensuring the continuing airworthiness of aircraft registered in Australia. This process aligns with international standards under Annex 8 to the Convention on International Civil Aviation, which places the responsibility of ensuring airworthiness on the State of Design and the State of Registry. The ADs are legislative instruments under section 46A of the Acts Interpretation Act 1901 and are subject to disallowance under section 6 of the Legislative Instruments Act 2003. CASA’s decision to issue or cancel an AD, such as the recent cancellation of AD/PA-32/77 concerning Piper PA-32 series aircraft, is made in accordance with subsection 84A(2) of the Act and is informed by the ongoing safety and regulatory needs of the aviation industry. The cancellation of AD/PA-32/77, effective from 17 January 2008, was deemed not to require public consultation or a Regulatory Impact Statement as it reduces regulatory burden without compromising safety.
Key Provisions
The Civil Aviation Act 1988, in section 98, empowers the Governor-General to establish regulations aimed at ensuring the safety of air navigation. These regulations include the Civil Aviation Safety Regulations 1998, which, under regulation 39.001, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specified types of aircraft or aeronautical products. Importantly, subregulation 39.001(5) clarifies that an AD is a disallowable instrument as defined by section 46A of the Acts Interpretation Act 1901, and consequently, it is considered a legislative instrument under section 6 of the Legislative Instruments Act 2003.
The obligations under these provisions require CASA to meticulously assess any AD issued by the State of Design concerning aircraft types registered in Australia. The State of Design, as outlined in Annex 8 to the Convention on International Civil Aviation, is responsible for ensuring the continuing airworthiness of aircraft types and must provide necessary information to the States of Registry. The State of Registry, in turn, must implement or adopt requirements that guarantee the continuing airworthiness of aircraft. For example, when CASA issues an Australian AD, it mandates compliance with the safety standards set by the State of Design, ensuring that Australian-registered aircraft meet international safety standards.
An instance of this regulatory process was evident in AD/PA-32/77, which was issued by CASA in 1991 for Piper PA-32 series aircraft. Following a review, CASA decided to cancel this AD, effective from 17 January 2008, due to the cessation of the original unsafe condition. As this cancellation reduces regulatory burden, CASA did not consult the Australian public. Additionally, the Office of Best Practice Regulation determined that no Regulatory Impact Statement was necessary for this AD cancellation. The AD cancellation was executed by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in compliance with subsection 84A(2) of the Act.
In terms of penalties and consequences, any breach of the regulations outlined in the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 could lead to significant civil and criminal consequences. Specifically, violations of ADs may result in penalties for non-compliance, which could include fines and, in severe cases, imprisonment. The exact penalties depend on the nature and severity of the breach, but they are intended to enforce strict adherence to air safety standards. CASA has the authority to take enforcement actions against individuals or entities that fail to comply with ADs, ensuring that the highest safety standards are maintained in the aviation sector.
