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/CESSNA 310/50 affecting Cessna 310 aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/CESSNA 310/50. The cancellation will become effective on 8 May 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 Acting 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, addressing the need for comprehensive and consistent regulation to ensure the safety of air navigation. The Act empowers the Governor-General to make regulations that promote the safety of air navigation, including the issuance of airworthiness directives (ADs). The Civil Aviation Safety Regulations 1998 further specify the processes for issuing ADs, which are legislative instruments that mandate corrective actions for identified safety issues in aircraft or aeronautical products. In accordance with international standards set by the International Civil Aviation Organization (ICAO), the State of Design has the responsibility for the continuing airworthiness of aircraft types, while the State of Registry ensures the airworthiness of individual aircraft. The Civil Aviation Safety Authority (CASA) acts on behalf of Australia in these matters, assessing international ADs and issuing Australian ADs as necessary to ensure compliance with safety standards. The cancellation of a particular AD for Cessna 310 aircraft exemplifies CASA's role in upholding these international and domestic safety obligations.
Scope and Application
The Civil Aviation Act 1988, supported by the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) that govern the continuing airworthiness of aircraft and aeronautical products within Australia. These regulations are designed to ensure compliance with safety standards as mandated by international agreements, particularly Annex 8 to the Convention on International Civil Aviation. The ADs apply to specific types of aircraft or aeronautical products, and they are issued by the State of Design and adopted by the State of Registry, in this case, CASA. The application of ADs is crucial for maintaining the safety and airworthiness of aircraft registered in Australia. The issuance and cancellation of ADs, such as AD/CESSNA 310/50, reflect Australia's commitment to international aviation safety standards and the practical considerations of ensuring the safe operation of aircraft. The legislative framework allows for the modification of ADs without public consultation, as determined by the Office of Best Practice Regulation, which has deemed ADs not to require a Regulatory Impact Statement. The ADs are legislative instruments subject to disallowance under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003.
Key Provisions
The Civil Aviation Act 1988 and its accompanying regulations, particularly regulation 39.001 of the Civil Aviation Safety Regulations 1998, provide the legislative framework for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). Section 98 of the Act empowers the Governor-General to make regulations for air navigation safety, which CASA exercises through issuing ADs for specific aircraft types or aeronautical products. Regulation 39.001(5) further classifies ADs as disallowable instruments, establishing them as legislative instruments under section 6 of the Legislative Instruments Act 2003. This regulatory structure ensures that ADs serve as a critical mechanism for maintaining the continuing airworthiness of aircraft, aligning with international standards set by Annex 8 to the Convention on International Civil Aviation.
Under the Civil Aviation Safety Regulations 1998, CASA has the authority and responsibility to issue ADs to ensure the safety of aircraft registered in Australia. When a State of Design issues an AD, CASA must assess the information and, if necessary, issue a corresponding Australian AD to enforce the required safety measures. This process ensures that all aircraft registered in Australia meet the necessary safety standards and comply with international regulations. The cancellation of an AD, such as AD/CESSNA 310/50 for Cessna 310 aircraft, occurs when CASA determines that the unsafe condition addressed by the AD no longer exists, as was the case when the AD was cancelled on 8 May 2008.
The obligations imposed on CASA under these regulations include the duty to assess and, if necessary, issue ADs in accordance with Australia’s obligations under the Convention on International Civil Aviation. CASA must ensure that the continuing airworthiness of aircraft is maintained by enforcing compliance with ADs. This involves a thorough evaluation of the information provided by the State of Design and the subsequent issuance of Australian ADs when required. The State of Registry, which in Australia is CASA, must also develop or adopt requirements to ensure the continuing airworthiness of aircraft, as mandated by Annex 8. These obligations underscore the critical role of CASA in enforcing safety standards and maintaining the airworthiness of aircraft registered in Australia.
Breach of the requirements under the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can result in significant legal consequences. While the specific offences and penalties are not detailed in the provided text, generally, non-compliance with ADs can lead to enforcement actions, including fines and potential criminal charges. The severity of these consequences can vary depending on the nature and extent of the breach, with potential penalties for non-compliance being substantial. Ensuring adherence to ADs is crucial for maintaining aviation safety and avoiding the associated legal repercussions.
