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.
Transport Canada has issued AD CF-88-01R1 affecting PT6B-36 and PT6B-36A engine models. Transport Canada is the State of Design for these engine models. CASA has assessed this AD and has issued Australian AD/PT6B/1, which will become effective on 9 July 2010.
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, Continuing Airworthiness, in the Airworthiness and Engineering Branch, on behalf of CASA, in accordance with subsection 94 (1) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Australian Parliament, establishes the legislative framework for the regulation of civil aviation in Australia. It provides the authority for the issuance of airworthiness directives (ADs) to ensure the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products, which are legislative instruments under the Acts Interpretation Act 1901 and Legislative Instruments Act 2003. The objective of these regulations is to ensure that aircraft remain airworthy and meet international safety standards as outlined in Annex 8 to the Convention on International Civil Aviation. The Civil Aviation Act 1988 thus addresses the need for a robust regulatory framework to manage and enforce airworthiness standards, aligning with global aviation safety protocols and ensuring the safe operation of aircraft within Australian airspace.
Scope and Application
The Civil Aviation (Airworthiness) Regulations 1998, under section 98 of the Civil Aviation Act 1988, empower the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) for specified types of aircraft or aeronautical products to ensure the safety of air navigation. These directives, as legislative instruments, are made by CASA in response to ADs issued by the State of Design of a particular aircraft type. For instance, in the case of PT6B-36 and PT6B-36A engine models, Transport Canada, as the State of Design, issued AD CF-88-01R1, prompting CASA to assess and subsequently issue Australian AD/PT6B/1. This legislative process is conducted in accordance with international obligations under the Convention on International Civil Aviation, which mandates the State of Registry to ensure the continuing airworthiness of aircraft within its jurisdiction. The regulatory framework does not require public consultation or a Regulatory Impact Statement for such directives, reflecting their technical nature and international alignment.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legislative framework within which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs). Under section 98 of the Act, the Governor-General can make regulations for the purposes of the Act, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 grants CASA the authority to issue ADs for specified kinds of aircraft or aeronautical products. Section 39.001(5) of these Regulations confirms that an AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901, meaning it is a legislative instrument as defined by section 6 of the Legislative Instruments Act 2003.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 require CASA to ensure the continuing airworthiness of aircraft registered in Australia. This obligation is particularly relevant when an AD is issued by the State of Design, as in the case of Transport Canada's AD CF-88-01R1 concerning PT6B-36 and PT6B-36A engine models. As the State of Design, Transport Canada has a responsibility under Annex 8 to the Convention on International Civil Aviation to provide information necessary for the continuing airworthiness of the aircraft type. CASA, as Australia’s national airworthiness authority, must then assess this information and, if appropriate, issue an Australian AD to mandate the requirements of the State of Design. In this instance, CASA has issued Australian AD/PT6B/1, which will become effective on 9 July 2010.
Failure to comply with ADs can have serious consequences. Under section 11 of the Civil Aviation Act 1988, an operator must not operate an aircraft unless it is airworthy. Section 47 of the Act makes it an offence for any person to contravene an AD, and such an offence is punishable by a fine of up to 120 penalty units or imprisonment for up to two years, or both. Additionally, CASA has the authority to take enforcement actions, including grounding non-compliant aircraft, which can result in significant operational disruptions and financial losses for the operator. Therefore, it is imperative for operators to comply with ADs to maintain the airworthiness of their aircraft and avoid potential legal and financial repercussions.
