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-28/41 affecting Piper PA-28 aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/PA-28/41. 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 provide a legislative framework for the regulation of civil aviation in Australia, with a primary focus on ensuring the safety of air navigation. This legislation empowers the Governor-General to make regulations that align with the Act's objectives, particularly concerning aviation safety. One such regulation, specified in the Civil Aviation Safety Regulations 1998, allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) that pertain to specific types of aircraft or aeronautical products. These directives serve as a critical tool for maintaining the continuing airworthiness of aircraft, aligning with international standards as outlined in Annex 8 to the Convention on International Civil Aviation. The ADs are instrumental in ensuring that the State of Design and the State of Registry uphold their responsibilities, thereby safeguarding the safety of Australian airspace. The cancellation of a specific airworthiness directive, such as AD/PA-28/41 for Piper PA-28 aircraft, reflects the dynamic nature of aviation safety regulations and the authority of CASA to respond promptly to emerging safety concerns.
Scope and Application
The Civil Aviation Act 1988, supported by the Civil Aviation Safety Regulations 1998, governs the issuance of airworthiness directives (ADs) under section 98 and regulation 39.001, respectively. These provisions empower the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products, ensuring compliance with safety standards. Such directives are legislative instruments, disallowable under section 46A of the Acts Interpretation Act 1901, and must adhere to the Legislative Instruments Act 2003. ADs are essential for maintaining the continuing airworthiness of aircraft, with the State of Design bearing overall responsibility and the State of Registry tasked with implementing the necessary requirements. In the case of AD/PA-28/41, which affected Piper PA-28 aircraft, CASA assessed the information and subsequently cancelled the directive, effective 5 June 2008, due to the resolution of the unsafe condition. This cancellation aligns with Australia’s commitments under the Convention on International Civil Aviation, and as such, no public consultation or Regulatory Impact Statement was required. The AD was issued by the Manager, Systems and New Technologies in the Airworthiness Engineering Branch of CASA, in accordance with the Act.
Key Provisions
The main operative sections of this legislation are section 98 of the Civil Aviation Act 1988 and regulation 39.001 of the Civil Aviation Safety Regulations 1998. Section 98 of the Act allows the Governor-General to make regulations for the safety of air navigation, while regulation 39.001 permits the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. Subregulation 39.001(5) specifies that an AD is a disallowable instrument, and thus a legislative instrument, under section 46A of the Acts Interpretation Act 1901.
The obligations and requirements imposed by this Act on the relevant parties include the responsibility of the State of Design to provide necessary information to ensure the continuing airworthiness of aircraft types, as stipulated under Annex 8 to the Convention on International Civil Aviation. The State of Registry is also tasked with developing or adopting requirements to ensure the continuing airworthiness of individual aircraft. CASA, as Australia’s national airworthiness authority, must assess information from the State of Design and, if necessary, issue an Australian AD to mandate the requirements of the State of Design. For instance, CASA assessed and subsequently cancelled Australian AD/PA-28/41, which affected Piper PA-28 aircraft, due to the unsafe condition no longer existing.
Regarding civil and criminal consequences, while the Act does not specify particular offences or penalties for non-compliance with ADs, failure to adhere to such directives can result in significant safety risks, potentially leading to aircraft being grounded or operations being restricted. Such actions could also result in legal consequences under other aviation regulations, including potential fines or penalties imposed by CASA. The maximum penalties for non-compliance with aviation regulations can vary, but they may include substantial fines and imprisonment, depending on the severity of the violation.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a framework for ensuring the continuing airworthiness of aircraft through the issuance of ADs. The Act and regulations impose clear responsibilities on both the State of Design and the State of Registry, with CASA playing a crucial role in assessing and implementing these directives within Australia. Non-compliance with these directives can have serious safety implications and potentially lead to legal and financial penalties.
