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 2005-19-19 affecting Boeing 737 model aircraft. The United States is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/B737/251, which will become effective on 24 November 2005.
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 A/Manager, New Technologies and Systems, in the Manufacturing, Certification and New Technologies Office, 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 within Australia, provides the authority for the issuance of airworthiness directives (ADs). These regulations are designed to maintain the safety standards of aircraft and aeronautical products, in line with international conventions such as the Convention on International Civil Aviation. The Civil Aviation Safety Regulations 1998 further elaborate on the requirements and processes for issuing ADs, ensuring that they meet the necessary safety standards. The Civil Aviation Safety Authority (CASA) is empowered to issue ADs under these regulations, which are considered legislative instruments as per the Acts Interpretation Act 1901. This legislative framework ensures that Australia adheres to its international obligations, while also maintaining the highest safety standards for its registered aircraft. The process of issuing ADs, particularly in response to directives from the State of Design, is streamlined and does not require public consultation, as determined by the Office of Regulatory Review.
Scope and Application
The Civil Aviation Act 1988 and the associated Civil Aviation Safety Regulations 1998 provide a framework for ensuring the safety of air navigation in Australia, with a particular emphasis on the continuing airworthiness of aircraft. Under the Act, the Civil Aviation Safety Authority (CASA) is empowered to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives are crucial as they mandate necessary safety measures to be undertaken by aircraft operators, ensuring that aircraft remain airworthy and meet safety standards. The issuance of ADs is a legislative instrument, subject to disallowance and scrutiny under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The ADs are integral to complying with international obligations under the Convention on International Civil Aviation, particularly the responsibilities of the State of Design and State of Registry regarding aircraft airworthiness. CASA, as Australia's national airworthiness authority, must evaluate international ADs and, if deemed necessary, issue corresponding Australian ADs to maintain safety standards within the national aviation framework. The process is streamlined and does not require public consultation due to its international compliance nature, and it is exempt from the requirement for a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988, in particular section 98, provides the authority for the Governor-General to create regulations that promote the safety of air navigation. Under this legislative framework, regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These directives are essential tools for maintaining the safety and airworthiness of aircraft. Subregulation 39.001(5) further clarifies that ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and are legislative instruments as per the Legislative Instruments Act 2003. This regulatory structure is aligned with international standards set by Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design the overarching responsibility for the continuing airworthiness of an aircraft type, requiring them to provide necessary information to ensure the airworthiness of the aircraft to States of Registry.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 are significant. The State of Design must issue ADs to address any identified safety issues and provide necessary information to maintain airworthiness. The State of Registry, in this case CASA, must assess the information from the State of Design and, if necessary, issue an Australian AD to enforce the requirements on aircraft registered in Australia. This process ensures that Australian-registered aircraft meet international safety standards. For example, the United States, as the State of Design for Boeing 737 models, issued AD 2005-19-19, which CASA assessed and subsequently issued as Australian AD/B737/251, effective from 24 November 2005.
The Civil Aviation Safety Regulations 1998, along with the Civil Aviation Act 1988, establish clear penalties for non-compliance with ADs. Failure to adhere to an AD can result in severe consequences, including fines and imprisonment. The specific penalties vary depending on the severity of the breach and the specific regulations involved. For instance, under the Civil Aviation Act 1988, serious breaches can lead to substantial fines and imprisonment terms, reflecting the critical nature of air safety regulations. Additionally, operators and owners of non-compliant aircraft may face operational restrictions or even grounding of their aircraft, further emphasising the importance of compliance with ADs.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a robust framework for issuing and enforcing airworthiness directives. These regulations mandate that CASA, as the national airworthiness authority, assess and implement ADs issued by the State of Design to ensure the safety of Australian-registered aircraft. Non-compliance with these directives can lead to significant penalties, including fines and imprisonment, underscoring the critical importance of adhering to these safety regulations.
