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 United States FAA has issued AD 2008-26-10 affecting Cessna 177 series aeroplanes. The United States is the State of Design for this aeroplane series. CASA has assessed this AD and has issued Australian AD/CESSNA 177/34, which will become effective on 16 January 2009.
As this AD is issued because of Australia’s obligations under Convention on International Civil Aviation, and because it is issued in response to an AD raised by the relevant State of Design, no consultation of the Australian public has taken place on this AD. The Office of Regulatory Review 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, enacted to ensure the safety and efficiency of civil aviation in Australia, empowers the Governor-General to create regulations aimed at enhancing air navigation safety. Complementing this, the Civil Aviation Safety Regulations 1998 enable the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are crucial for maintaining the continuing airworthiness of aircraft and are aligned with international standards, particularly under Annex 8 of the Convention on International Civil Aviation. This legislation allows CASA to mandate Australian ADs in response to directives from the State of Design, ensuring that Australian aircraft meet international safety standards.
The process of issuing ADs is governed by the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003, which classify ADs as legislative instruments. CASA, as Australia’s national airworthiness authority, is responsible for assessing and issuing these directives, particularly when international obligations necessitate it. The issuance of ADs is typically a direct response to directives from the State of Design, such as the United States in the case of Cessna 177 series aeroplanes, and does not involve public consultation as it is based on international obligations and assessments. This legislative framework ensures that Australian aviation remains compliant with global safety standards, thereby safeguarding the interests of both domestic and international aviation stakeholders.
Scope and Application
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These directives are crucial for ensuring the continuing airworthiness of aircraft, aligning with Australia's obligations under Annex 8 to the Convention on International Civil Aviation. The authority to issue such directives stems from section 98 of the Civil Aviation Act 1988, with the intent to promote the safety of air navigation. Each AD is a legislative instrument, subject to disallowance under section 46A of the Acts Interpretation Act 1901, and must be reviewed in accordance with the Legislative Instruments Act 2003. The ADs issued by CASA respond directly to those issued by the State of Design, ensuring that Australian-registered aircraft meet international safety standards. The issuance of ADs like AD/CESSNA 177/34, which corresponds to FAA AD 2008-26-10, exemplifies the process wherein CASA mandates the requirements of the State of Design to ensure the continuing airworthiness of aircraft registered in Australia.
Key Provisions
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, provides the legislative framework under which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) to ensure the safety of air navigation. Specifically, section 98 of the Civil Aviation Act 1988 allows the Governor-General to make regulations for the purposes of the Act, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers CASA to issue ADs for types of aircraft or aeronautical products. These ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and are legislative instruments as per section 6 of the Legislative Instruments Act 2003.
The obligations imposed by the Act and regulations primarily rest on CASA and the State of Registry. CASA, as Australia's national airworthiness authority, must assess any ADs issued by the State of Design that affect aircraft on the Australian Register and, if necessary, issue corresponding Australian ADs. The State of Registry is responsible for ensuring the continuing airworthiness of individual aircraft, developing or adopting requirements to meet this responsibility as stipulated in Annex 8 to the Convention on International Civil Aviation. This means that when an AD is issued by the State of Design, the State of Registry must ensure that these directives are implemented and complied with to maintain the airworthiness of the aircraft in question.
Failure to comply with ADs can result in significant consequences. While the specific offences, penalties, and consequences for breach are not detailed in the provided text, it is clear that non-compliance with airworthiness directives can lead to safety risks and legal repercussions. In general, non-compliance with ADs can result in civil penalties, criminal charges, and potentially grounding of the aircraft until the required actions are taken to address the airworthiness issues identified by the ADs. The maximum penalties for such breaches can include substantial fines and imprisonment, reflecting the critical importance of airworthiness and safety in civil aviation.
