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 2007-0235 affecting Pilatus PC 12 aircraft. EASA acts on behalf of Switzerland, the State of Design for these types. CASA has assessed this AD and has issued Australian AD/PC-12/50 which will become effective on 25 October 2007.
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, Systems 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 by the Australian Parliament, is a foundational piece of legislation that governs civil aviation in Australia, ensuring the safety, efficiency and orderly growth of civil aviation. One of its key provisions is the ability to issue airworthiness directives (ADs) to address safety concerns or deficiencies in aircraft, as outlined in regulation 39.001 of the Civil Aviation Safety Regulations 1998. This regulatory mechanism is crucial for maintaining the continuing airworthiness of aircraft registered in Australia, ensuring compliance with international standards set by the Convention on International Civil Aviation.
The issuance of airworthiness directives, such as the AD/PC-12/50 issued by CASA in response to an EASA directive concerning Pilatus PC 12 aircraft, exemplifies the practical application of the Civil Aviation Act 1988 in harmonising national aviation safety standards with international obligations. These directives, which are legislative instruments under the Legislative Instruments Act 2003, are issued without public consultation, as determined by the Office of Best Practice Regulation, which has also concluded that they do not require a Regulatory Impact Statement. This streamlined process allows the Civil Aviation Safety Authority (CASA) to act swiftly and effectively to address safety issues, thereby fulfilling the policy objective of maintaining high safety standards in Australian civil aviation.
Scope and Application
The Civil Aviation Act 1988, supported by the Civil Aviation Safety Regulations 1998, establishes the legislative framework for issuing airworthiness directives (ADs) in Australia. These directives apply to aircraft or aeronautical products and are issued by the Civil Aviation Safety Authority (CASA) to ensure the continuing airworthiness of these entities. ADs serve as a critical mechanism for enforcing safety standards in the aviation industry, aligning with international obligations under the Convention on International Civil Aviation. The authority to issue these directives stems from regulation 39.001, which mandates CASA to issue ADs for specified types of aircraft or aeronautical products. Each AD is considered a legislative instrument under the Legislative Instruments Act 2003, subject to disallowance as per the Acts Interpretation Act 1901. Although these directives are integral to maintaining safety standards, they are not subject to public consultation or a Regulatory Impact Statement due to their alignment with international conventions and the nature of the safety measures they implement.
Key Provisions
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, provides the legal framework for the issuance and enforcement of airworthiness directives (ADs). Under section 98 of the Act, the Governor-General has the authority to make regulations that serve the safety of air navigation. Specifically, regulation 39.001 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for particular types of aircraft or aeronautical products. These ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and are legislative instruments in accordance with section 6 of the Legislative Instruments Act 2003.
The issuance of ADs is governed by international standards set forth in Annex 8 to the Convention on International Civil Aviation, which designates the State of Design as having overall responsibility for the continuing airworthiness of an aircraft type. This state must provide necessary information to ensure the airworthiness of the aircraft to the States of Registry. The State of Registry, in turn, is responsible for the ongoing airworthiness of individual aircraft and must develop or adopt requirements to maintain this airworthiness. When the State of Design issues an AD, CASA, as Australia's national airworthiness authority, must evaluate this information and, if deemed appropriate, issue an Australian AD to enforce the requirements of the State of Design.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 require CASA to meticulously assess any foreign ADs and determine their applicability to aircraft registered in Australia. This process ensures that Australian ADs are consistent with international safety standards and are tailored to meet the specific needs of the Australian aviation industry. CASA must also ensure that these ADs are issued promptly and efficiently to maintain the safety and airworthiness of aircraft operating within Australian airspace.
In terms of consequences for non-compliance, breaches of ADs can lead to serious civil and criminal penalties. The Act does not specify maximum penalties for violations of ADs, but non-compliance can result in severe consequences, including the grounding of aircraft, fines, and potential criminal charges. The rigorous enforcement of ADs is critical to maintaining the high safety standards expected in the aviation industry, and failure to adhere to these directives can have significant legal and safety implications for both operators and regulators.
