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 EASA has issued AD 2006-0118R1–E affecting several German Supplemental Type Certificates and Swedish CTT Systems installed on various aircraft models. Europe is the State of Design for LBA STC’s and Equipment manufactured by CTT Systems. CASA has assessed this AD and has issued Australian AD/AIRCON/14, which will become effective on 19 May 2006.
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, Airframes 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 was enacted to establish a legislative framework for civil aviation in Australia, ensuring the safety and efficiency of air navigation. The Act empowers the Governor-General to make regulations necessary for air safety, as exemplified by the Civil Aviation Safety Regulations 1998. These regulations allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft and aeronautical products. Such directives are instrumental in maintaining the continuing airworthiness of aircraft, aligning with Australia's responsibilities under the Convention on International Civil Aviation and the obligations of the relevant State of Design. This legislative structure ensures that Australia meets international standards and effectively manages the safety of air navigation within its jurisdiction.
Scope and Application
The Civil Aviation Safety Regulations 1998, pursuant to section 98 of the Civil Aviation Act 1988, empower 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. These ADs, which are considered legislative instruments under section 46A of the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003, are integral to maintaining the continuing airworthiness of aircraft and are issued by most International Civil Aviation Organization (ICAO) Contracting States, including Australia. The State of Registry, such as CASA in Australia, is tasked with ensuring the ongoing airworthiness of individual aircraft, developing or adopting necessary requirements in line with Annex 8 of the Convention on International Civil Aviation. In instances where a State of Design issues an AD, CASA must evaluate the information and, if appropriate, issue a corresponding Australian AD. This legislative framework underscores Australia's commitment to international aviation safety standards and ensures alignment with global regulatory practices.
Key Provisions
The Civil Aviation Act 1988 (section 98) provides the legal basis for the Governor-General to enact regulations aimed at ensuring the safety of air navigation. In line with this, regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. This regulatory framework is designed to maintain the safety and airworthiness of aircraft, and the ADs are considered legislative instruments under the Acts Interpretation Act 1901 (section 46A) and the Legislative Instruments Act 2003 (section 6).
The obligations under the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 place significant responsibility on CASA and the States of Registry to ensure the continuing airworthiness of aircraft. According to Annex 8 to the Convention on International Civil Aviation, the State of Design has the overarching responsibility for the continuing airworthiness of an aircraft type, requiring them to provide necessary information to the appropriate States of Registry. CASA, as Australia’s national airworthiness authority, must assess this information and, if necessary, issue an Australian AD to enforce the requirements of the State of Design. This ensures that any safety issues identified by the State of Design are adequately addressed within Australia's aviation sector.
Failure to comply with an airworthiness directive can result in serious legal and safety consequences. Under the Civil Aviation Act 1988, non-compliance with ADs can lead to significant penalties. The Act and associated regulations may impose both civil and criminal penalties for breaches, which can include fines and imprisonment. The exact penalties depend on the severity of the breach and the specific provisions of the Act. It is crucial for aircraft operators and owners to adhere to ADs to avoid these potential penalties and ensure the continued safe operation of their aircraft.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a robust framework for issuing and enforcing airworthiness directives to maintain the safety and airworthiness of aircraft. CASA plays a pivotal role in this process, ensuring that any safety concerns identified by the State of Design are addressed through the issuance of Australian ADs. Non-compliance with these directives can result in severe civil and criminal penalties, highlighting the importance of adhering to the regulations to maintain aviation safety standards.
