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.
The Civil Aviation Safety Authority or its predecessors issued AD/DHC-1/10 affecting De Havilland DHC-1 model aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/DHC-1/10. The cancellation will become effective on 25 September 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, Airframe and Structures, in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted to regulate and ensure the safety of civil aviation in Australia, empowers the Governor-General to make regulations for the purposes of the Act and in the interests of the safety of air navigation. The Civil Aviation Safety Regulations 1998, made under the Act, provide for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) to maintain the safety of aircraft and aeronautical products. These directives are essential tools for ensuring the continuing airworthiness of aircraft, as mandated by Annex 8 to the Convention on International Civil Aviation, which assigns responsibility to the State of Design for providing necessary information and to the State of Registry for implementing continuing airworthiness requirements. CASA, acting on behalf of Australia’s obligations under the Convention, has the authority to issue and cancel ADs as needed to address safety concerns, as evidenced by the cancellation of AD/DHC-1/10 for De Havilland DHC-1 model aeroplanes, which will become effective on 25 September 2008. This cancellation, necessitated by the resolution of the unsafe condition, did not require public consultation or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legal framework for the issuance of airworthiness directives (ADs) in Australia, with the overarching aim of ensuring the safety of air navigation. Pursuant to regulation 39.001 of the Civil Aviation Safety Regulations, the Civil Aviation Safety Authority (CASA) has the authority to issue ADs for specific types of aircraft or aeronautical products. These ADs serve as legislative instruments under the Legislative Instruments Act 2003 and are essential for maintaining the continuing airworthiness of aircraft, as mandated by Annex 8 to the Convention on International Civil Aviation. The State of Design and the State of Registry bear responsibilities for ensuring that appropriate information and requirements are provided to maintain airworthiness. CASA has the discretion to cancel existing ADs, such as Australian AD/DHC-1/10 for De Havilland DHC-1 model aeroplanes, if the unsafe conditions they address no longer exist, as determined by CASA's assessment. The cancellation of such an AD, in line with international obligations, does not require public consultation or a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988 and Civil Aviation Safety Regulations 1998 together provide a framework for issuing airworthiness directives (ADs) as a means to ensure the safety of air navigation. Under section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to make regulations that serve the interests of air navigation safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. These ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and are thus legislative instruments, as stated in subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998.
The obligations imposed by these regulations require CASA to issue ADs to ensure the continuing airworthiness of aircraft. The State of Registry of an individual aircraft must adhere to these ADs to maintain the safety and airworthiness of the aircraft. Additionally, the State of Design has a responsibility under Annex 8 to the Convention on International Civil Aviation to provide any necessary information to ensure the continuing airworthiness of the aircraft type to the appropriate States of Registry. In Australia, CASA has the authority to develop, adopt, and enforce these ADs to meet these international obligations.
The consequences of failing to comply with ADs can be severe. Under section 84A of the Civil Aviation Act 1988, CASA can take action against individuals or entities that do not comply with an AD, which may result in fines or other penalties. Although the Civil Aviation Safety Regulations 1998 do not specify the exact penalties, non-compliance with ADs can lead to serious civil or criminal consequences, including potential prosecution by CASA. The specific penalties are outlined in the Civil Aviation Act 1988 and may include fines and imprisonment, depending on the severity of the breach. The authority to issue ADs and enforce compliance is critical to maintaining the high safety standards required in civil aviation.
