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 New Zealand CAA has issued AD DCA/CT4/7 affecting Pacific Aerospace CT4 model aircraft. New Zealand is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/CT4/2, which will become effective on 23 November 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, enacted by the Australian Parliament, serves to ensure the safety of air navigation within Australia. This legislation provides the legal framework for the regulation of civil aviation, addressing gaps in safety standards and operational practices. One critical aspect of this Act is the issuance of airworthiness directives (ADs) under section 98, empowering the Governor-General to make regulations that maintain the safety of air navigation. The Civil Aviation Safety Regulations 1998 further detail the procedures for issuing ADs, which are legislative instruments that mandate the continuing airworthiness of aircraft. These regulations ensure that Australia meets its international obligations under the Convention on International Civil Aviation, particularly concerning the responsibility of the State of Design for the airworthiness of aircraft types. The Civil Aviation Safety Authority (CASA) plays a pivotal role in implementing these directives, particularly when responding to ADs issued by other countries, such as the New Zealand Civil Aviation Authority, ensuring that Australian standards align with global safety requirements.
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 types of aircraft or aeronautical products. These directives are legislative instruments that are essential for maintaining the safety of air navigation as stipulated under section 98 of the Civil Aviation Act 1988. An AD becomes effective once issued by CASA, which must align with the requirements of the relevant State of Design, in this case, New Zealand, for the Pacific Aerospace CT4 model aircraft. The AD/CT4/2 issued by CASA will mandate the requirements originally set by the New Zealand Civil Aviation Authority’s AD DCA/CT4/7. This process ensures that the continuing airworthiness of aircraft registered in Australia is upheld in accordance with international standards set by the Convention on International Civil Aviation. The issuance of such directives does not require public consultation or a Regulatory Impact Statement, as determined by the Office of Regulatory Review.
Key Provisions
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are legislative instruments that are subject to disallowance under section 46A of the Acts Interpretation Act 1901 and must be registered under the Legislative Instruments Act 2003. ADs are critical for ensuring the continuing airworthiness of aircraft, as they are mandated by Annex 8 to the Convention on International Civil Aviation, which assigns responsibility to the State of Design for the ongoing airworthiness of aircraft types. The State of Registry, such as CASA in Australia, is responsible for implementing these ADs to ensure that aircraft remain airworthy.
In the case of the New Zealand Civil Aviation Authority (NZCAA) issuing AD DCA/CT4/7 for the Pacific Aerospace CT4 model aircraft, CASA, as Australia’s national airworthiness authority, is required to assess the information provided by the State of Design. CASA subsequently issues an Australian AD, such as AD/CT4/2, to mandate the requirements of the NZCAA’s directive. This process ensures that Australian aircraft comply with international standards for airworthiness, as mandated by the Convention on International Civil Aviation. Since this AD responds to an international obligation and an AD from the relevant State of Design, no public consultation has been required, and a Regulatory Impact Statement is not necessary.
Under the Civil Aviation Act 1988, CASA must adhere to the requirements set out in the Civil Aviation Safety Regulations 1998 when issuing ADs. This includes ensuring that any AD issued is consistent with the international obligations under the Convention on International Civil Aviation. CASA is also required to ensure that the ADs issued are effectively communicated to the relevant stakeholders, including aircraft operators and maintenance providers. These obligations ensure that the ADs are implemented efficiently and that the airworthiness of aircraft is maintained to the highest safety standards.
Failure to comply with an AD issued by CASA can lead to significant legal consequences. Under section 84A of the Civil Aviation Act 1988, a person who contravenes an AD commits an offence. The penalties for such an offence can include fines and imprisonment. The maximum penalty for contravening an AD can vary depending on the nature and severity of the offence, but it can include substantial fines and imprisonment terms that reflect the seriousness of the non-compliance. Ensuring compliance with ADs is therefore crucial for maintaining the safety and airworthiness of aircraft operating within Australia.
