CIVIL AVIATION ACT 1988
CIVIL AVIATION 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 Swiss Federal Office for Civil Aviation has issued AD HB-2005-263 affecting PC-6 model aircraft. Switzerland is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/PC-6/51, Amendment 1, which will become effective on 4 August 2005. This AD cancels and replaces the previous issue.
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 Section Head - Airframes, Airworthiness Standards Branch, Standards Division, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Australian Parliament, aims to ensure the safety of air navigation and the continuing airworthiness of aircraft. One of its key provisions allows the Governor-General to make regulations for these purposes. The Civil Aviation Safety Regulations 1998 further detail how airworthiness directives (ADs) can be issued by the Civil Aviation Safety Authority (CASA) for specific kinds of aircraft or aeronautical products. These ADs are legislative instruments that comply with international standards, particularly those outlined in Annex 8 to the Convention on International Civil Aviation. CASA, as the national airworthiness authority, must assess and issue Australian ADs when necessary, particularly when corresponding directives are issued by the State of Design. This ensures that aircraft registered in Australia meet international safety standards and continuing airworthiness requirements. The ADs are issued in accordance with the legislative framework and do not require public consultation or a Regulatory Impact Statement, as determined by the Office of Regulatory Review.
Scope and Application
The Civil Aviation Act 1988, supported by the Civil Aviation Regulations 1998, provides the legislative framework under which airworthiness directives (ADs) are issued in Australia. These directives are instrumental in ensuring the safety of air navigation and are issued by the Civil Aviation Safety Authority (CASA) for specific types of aircraft or aeronautical products as per regulation 39.001 of the Civil Aviation Safety Regulations 1998. Such ADs are legislative instruments, disallowable under section 46A of the Acts Interpretation Act 1901 and subject to the provisions of the Legislative Instruments Act 2003. They are issued under the authority granted by section 98 of the Civil Aviation Act 1988, with the aim of maintaining the continuing airworthiness of aircraft registered in Australia, aligning with international obligations under the Convention on International Civil Aviation. The State of Design, such as Switzerland in this case, holds the primary responsibility for the airworthiness of an aircraft type, while the State of Registry, in this instance Australia, is tasked with enforcing these standards. This specific AD, issued by CASA, is a response to an AD issued by the Swiss Federal Office for Civil Aviation for PC-6 model aircraft and mandates compliance with the safety requirements outlined by the State of Design.
Key Provisions
The Civil Aviation Act 1988, specifically section 98, empowers the Governor-General to create regulations aimed at ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 extends this authority to the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain aircraft or aeronautical products. These ADs are considered legislative instruments as per section 6 of the Legislative Instruments Act 2003 and can be disallowed under section 46A of the Acts Interpretation Act 1901. Essentially, ADs serve as a critical tool for maintaining the continuing airworthiness of aircraft and are a standard practice among International Civil Aviation Organization (ICAO) Contracting States.
Under the obligations outlined in the Act, CASA, as Australia's national airworthiness authority, must assess any AD issued by a State of Design, which is the country responsible for the aircraft's design. For instance, if Switzerland, the State of Design for the PC-6 model aircraft, issues an AD, CASA is required to evaluate this directive and determine its applicability to Australian-registered aircraft. If deemed necessary, CASA must then issue a corresponding Australian AD to enforce the requirements set forth by the State of Design. This process ensures that Australian aircraft meet international standards for airworthiness.
Failure to comply with an AD can result in significant legal consequences. While the Civil Aviation Act 1988 does not explicitly detail the penalties for non-compliance with ADs, breaches of regulations under the Act can lead to substantial fines and imprisonment. The severity of these penalties is influenced by the nature and extent of the non-compliance. In some cases, non-compliance can result in the grounding of an aircraft, which can have severe operational and financial repercussions for the operators.
In summary, the issuance and enforcement of ADs under the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 are pivotal in maintaining the safety and airworthiness of aircraft registered in Australia. CASA's role in assessing and implementing these directives ensures that Australian aviation standards align with international obligations and safety requirements. Non-compliance with ADs can result in severe legal and operational penalties, underscoring the importance of adhering to these regulatory mandates.
