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 Brazilian ANAC has issued AD 2008-08-01 affecting Embraer EMB-120 model aircraft. Brazil is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/EMB-120/48, which will become effective on 18 December 2008.
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 Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Airframes& 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 by the Australian Parliament, serves to provide a regulatory framework for civil aviation in Australia, with a primary focus on ensuring the safety of air navigation. Under this Act, the Civil Aviation Safety Regulations 1998 were formulated to further delineate the safety standards and regulatory measures necessary for the operation of aircraft within Australia. One key provision of these regulations is the authority granted to the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, as outlined in regulation 39.001. This legislative framework was designed to address the need for consistent and enforceable safety standards across the aviation sector, in line with Australia's international obligations under the Convention on International Civil Aviation. The policy objective is to ensure that the continuing airworthiness of aircraft is maintained in accordance with internationally accepted standards, thereby safeguarding the safety of air navigation.
Scope and Application
The Civil Aviation Act 1988 and its accompanying Civil Aviation Safety Regulations 1998 empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) to ensure the safety of air navigation. These ADs apply to specific kinds of aircraft or aeronautical products and are legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The State of Design has the primary responsibility for the continuing airworthiness of aircraft types, and States of Registry, including Australia, must ensure that aircraft meet these standards. In the case of Embraer EMB-120 model aircraft, following the issuance of a Brazilian AD by the Brazilian National Civil Aviation Agency (ANAC), CASA assessed the information and issued its own AD, AD/EMB-120/48, to align with international obligations under the Convention on International Civil Aviation. This process does not require public consultation or a Regulatory Impact Statement as it pertains to international obligations and is issued in response to an AD by the relevant State of Design.
Key Provisions
The Civil Aviation Act 1988, specifically under section 98, empowers the Governor-General to enact regulations aimed at enhancing the safety of air navigation. The Civil Aviation Safety Regulations 1998, through regulation 39.001, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. This regulatory framework ensures that all aircraft maintain a standard of airworthiness that aligns with international safety standards, particularly those set by the International Civil Aviation Organization (ICAO). Subregulation 39.001(5) further classifies ADs as disallowable instruments under section 46A of the Acts Interpretation Act 1901, thereby categorising them as legislative instruments under section 6 of the Legislative Instruments Act 2003.
The obligations imposed by these regulations primarily rest on CASA, which must evaluate any airworthiness directives issued by the State of Design and determine if they need to be implemented within Australia. As Australia’s national airworthiness authority, CASA must ensure that any airworthiness directives issued by the State of Design are assessed and, if necessary, converted into Australian ADs to maintain the continuing airworthiness of aircraft registered in Australia. This process is crucial for upholding international standards and ensuring that aircraft operating within Australian airspace meet stringent safety criteria.
In terms of enforcement and consequences, the Act does not explicitly list specific offences or penalties for non-compliance with ADs. However, the overarching regulatory framework under which ADs are issued implies that failure to comply with such directives could result in severe repercussions. These might include the grounding of aircraft, fines, or other legal actions deemed necessary by CASA to enforce compliance. Given the critical nature of airworthiness directives in maintaining aviation safety, non-compliance could lead to significant civil or criminal penalties, underscoring the importance of adhering to these regulations.
While the specific penalties for non-compliance are not detailed in the provided text, the implications of failing to adhere to airworthiness directives can be severe. The gravity of non-compliance could lead to actions such as the suspension or revocation of airworthiness certificates, thereby grounding the affected aircraft until the required actions are taken to rectify any safety issues. Additionally, CASA may impose fines or other financial penalties on operators who fail to comply with ADs, highlighting the serious consequences of neglecting airworthiness requirements. This regulatory approach ensures that all stakeholders are held accountable for maintaining the highest standards of aviation safety.
