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 European Aviation Safety Authority (EASA) has issued AD 2007-0056 affecting BAe Jetstream 4100 model aircraft. EASA acts on behalf of the United Kingdom, the State of Design for this type. CASA has assessed this AD and has issued Australian AD/J4100/6, which will become effective on 20 February 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 in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted to address the need for a comprehensive regulatory framework governing civil aviation in Australia, includes provisions for the issuance of airworthiness directives to ensure the safety of air navigation. Under section 98 of this Act, the Governor-General has the authority to create regulations that serve the interests of air navigation safety. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives for certain types of aircraft or aeronautical products. These directives are essential for maintaining the continuing airworthiness of aircraft, aligning with international standards set forth in Annex 8 to the Convention on International Civil Aviation. CASA, as Australia’s national airworthiness authority, must evaluate and, when necessary, implement Australian airworthiness directives in response to those issued by the aircraft’s State of Design, ensuring compliance with both domestic and international aviation safety standards.
Scope and Application
The Civil Aviation Act 1988, through its regulatory mechanisms, applies to the safety of air navigation within Australia and mandates the creation of safety regulations to protect this domain. The Civil Aviation Safety Regulations 1998, particularly regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives are legislative instruments under section 46A of the Acts Interpretation Act 1901 and are issued to ensure the continuing airworthiness of aircraft registered in Australia, aligning with the responsibilities of the State of Registry as outlined in Annex 8 to the Convention on International Civil Aviation. The issuance of ADs, such as the one issued by CASA in response to EASA’s AD 2007-0056 for the BAe Jetstream 4100 model, is a direct result of international cooperation and obligations, and thus does not require public consultation. The ADs are issued by CASA to enforce safety measures, ensuring compliance with international standards and the specific safety requirements of aircraft registered within Australia.
Key Provisions
The Civil Aviation Act 1988 and the associated regulations, specifically under section 98 and regulation 39.001, empower the Governor-General to enact regulations that ensure the safety of air navigation. According to regulation 39.001(5) of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) is authorised to issue airworthiness directives (ADs) for particular types of aircraft or aeronautical products. These directives are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and as such, they are legislative instruments under section 6 of the Legislative Instruments Act 2003. ADs are a fundamental mechanism for ensuring the continuing airworthiness of aircraft types, a responsibility that rests with the State of Design, as outlined in Annex 8 to the Convention on International Civil Aviation. The State of Design must provide the necessary information to maintain airworthiness to the State of Registry. In Australia, CASA, as the national airworthiness authority, is obligated to assess any ADs issued by the State of Design and, if necessary, issue corresponding Australian ADs to enforce the requirements.
Entities and individuals governed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 are subject to specific obligations and requirements related to airworthiness directives. The State of Registry, which in Australia is CASA, must develop or adopt the necessary requirements to ensure the continuing airworthiness of aircraft registered in Australia. When an AD is issued by the State of Design, CASA must evaluate the directive and, if deemed appropriate, issue a corresponding Australian AD. This ensures that the safety standards and requirements set forth by the State of Design are effectively implemented within Australia. Operators of aircraft affected by an AD must comply with the directive’s requirements, including any mandated inspections, repairs, or modifications, to maintain the airworthiness of their aircraft. Failure to comply with an AD can lead to serious safety risks and potential legal consequences.
Failure to comply with an airworthiness directive can result in significant legal and safety consequences. Under the Civil Aviation Act 1988, non-compliance with an AD may be considered an offence, leading to both civil and criminal penalties. The Act allows for the imposition of fines and potential imprisonment for individuals and entities found in breach of an AD. The specific penalties vary depending on the nature and severity of the breach. For instance, under section 109 of the Act, CASA may issue a penalty notice for certain minor breaches, while more serious breaches may be prosecuted in court, leading to fines of up to $22,200 for individuals and $111,000 for corporations, as well as potential imprisonment. Additionally, non-compliance with an AD can result in the grounding of an aircraft, which can have severe operational and financial repercussions for operators. Ensuring adherence to ADs is therefore critical for maintaining aviation safety and avoiding legal repercussions.
