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/PDH/3 affecting all De Havilland model 3HFB (3/1000/2) propellers. CASA has assessed this AD and as a result has cancelled Australian AD/PDH/3. The cancellation will become effective on 9 April 2009. 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 Group, 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 the regulation of civil aviation in Australia, aiming to ensure the safety and efficiency of air navigation. Under this Act, the Governor-General is empowered to create regulations that serve the interests of air navigation safety. The Civil Aviation Safety Regulations 1998 further detail the regulatory measures, including the issuance of airworthiness directives by the Civil Aviation Safety Authority (CASA). These directives are crucial for maintaining the continuing airworthiness of aircraft, aligning with international standards as set out in Annex 8 to the Convention on International Civil Aviation. CASA, as Australia's national airworthiness authority, is tasked with ensuring that all aircraft meet the necessary safety standards, often necessitating the issuance or cancellation of such directives in response to international safety directives or the resolution of specific safety issues. The policy objective is to uphold the highest safety standards in civil aviation, thereby protecting both the public and the industry.
Scope and Application
The Civil Aviation Act 1988, as amended by the Civil Aviation Safety Regulations 1998, provides the framework for the regulation of airworthiness directives (ADs) in Australia. These regulations empower the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products, aiming to maintain and ensure the safety of air navigation. The issuance of ADs is a legislative instrument under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. ADs are crucial for the continuing airworthiness of aircraft, a responsibility that rests with the State of Design under Annex 8 of the Convention on International Civil Aviation, while the State of Registry, in this case CASA, must enforce these directives. This legislation applies to all aircraft registered in Australia, thereby affecting aircraft manufacturers, operators, and maintenance providers within the Australian jurisdiction. The scope of the ADs extends nationally, aligning with Australia’s obligations under international civil aviation conventions. The ADs can be subject to cancellation if the unsafe conditions they were intended to address no longer exist, as evidenced by the cancellation of AD/PDH/3 for De Havilland model 3HFB (3/1000/2) propellers, which was deemed unnecessary following an assessment by CASA.
Key Provisions
The Civil Aviation Act 1988, specifically under section 98, empowers the Governor-General to create regulations aimed at ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 extends this authority to the Civil Aviation Safety Authority (CASA), allowing it to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. Subregulation 39.001(5) further clarifies that ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and as such, are legislative instruments under section 6 of the Legislative Instruments Act 2003. This legislative framework ensures that ADs, which are crucial for maintaining the continuing airworthiness of aircraft, are issued in a manner consistent with Australian law and international standards.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 on parties and entities primarily revolve around the maintenance of aircraft airworthiness. Under these regulations, the State of Design is tasked with the overall responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to the appropriate States of Registry. The State of Registry, in turn, must develop or adopt requirements to ensure that individual aircraft remain airworthy. For Australian-registered aircraft, CASA, as the national airworthiness authority, must assess information from State of Design ADs and, if appropriate, issue corresponding Australian ADs to enforce the required safety measures.
Failure to comply with the provisions of ADs can lead to significant consequences. Although the text does not explicitly detail specific offences or penalties for non-compliance with ADs, it is understood that non-compliance with such regulations can result in severe safety risks and legal repercussions. The potential civil and criminal consequences can include fines, suspension or revocation of aircraft operating certificates, and criminal charges for individuals responsible for the non-compliance. The exact penalties may vary based on the severity of the violation and are typically prescribed in other sections of the Civil Aviation Act 1988 or related regulations.
The legislative process for issuing and cancelling ADs is also outlined in the text. For instance, CASA issued AD/PDH/3 concerning De Havilland model 3HFB (3/1000/2) propellers but later cancelled it on 9 April 2009 due to the unsafe condition no longer existing. The cancellation of this AD was made without public consultation, as it was determined that ADs do not require a Regulatory Impact Statement. This decision was made by the Manager, Systems and New Technologies, in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A(2) of the Act. This procedure highlights the streamlined yet rigorous approach CASA takes to ensure the safety and compliance of aircraft in Australia.
