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. An AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901.
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 Austrian Austro Control Group issued AD A-2004-004 R1, affecting Rotax Aircraft Engines, in 2004. Austria is the State of Design for Rotax Engines. As a result of a request from industry, CASA has amended the equivalent Australian AD to Amendment 1. The amended AD, AD/ROTAX/21 Amendment 1, will become effective on 17 March 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 - Systems, Airworthiness Standards Branch, Standards Division, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to regulate civil aviation in Australia and to ensure the safety and efficiency of air navigation. The Act empowers the Governor-General to make regulations that serve the interests of air navigation safety, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) as per regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs are crucial for maintaining the continuing airworthiness of aircraft types, aligning with international standards under Annex 8 of the Convention on International Civil Aviation. The State of Design, responsible for the aircraft type, issues ADs that must be assessed and, if appropriate, adopted by the State of Registry, which in Australia is CASA. This legislative framework ensures that Australian aircraft meet international safety standards and facilitates the exchange of continuing airworthiness information among contracting states.
Scope and Application
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Regulations 1998, governs the issue of airworthiness directives (ADs) which are crucial for ensuring the safety of air navigation. Under these regulations, the Civil Aviation Safety Authority (CASA) has the authority to issue ADs for specific types of aircraft or aeronautical products. These ADs are designed to address issues related to the continuing airworthiness of aircraft and are mandated by Australia's obligations under the Convention on International Civil Aviation, particularly under Annex 8, which designates the State of Design as responsible for the continuing airworthiness of an aircraft type. The State of Registry, in this case CASA as Australia’s national airworthiness authority, must then assess this information and issue corresponding ADs if deemed necessary. The ADs are not subject to disallowance under section 46A of the Acts Interpretation Act 1901 and do not require public consultation or a Regulatory Impact Statement, as determined by the Office of Regulatory Review. This process ensures that Australian ADs align with international standards and maintain the high safety levels required for aviation operations within Australia.
Key Provisions
The Civil Aviation Act 1988, particularly section 98, empowers the Governor-General to establish regulations aimed at ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 further allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These ADs are critical tools in maintaining the continuing airworthiness of aircraft, as they mandate specific actions or requirements to ensure safety and compliance with international standards. The ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, which means they can be annulled by either house of the Parliament.
Under Annex 8 to the Convention on International Civil Aviation, the State of Design, such as Austria for Rotax Aircraft Engines, holds the primary responsibility for the continuing airworthiness of an aircraft type. This includes providing necessary information to ensure the safety of the aircraft type to the States of Registry. In Australia, CASA, as the national airworthiness authority, must assess this information and, if appropriate, issue an Australian AD to enforce the requirements of the State of Design. This process ensures that Australian-registered aircraft meet the necessary safety standards as mandated by international agreements.
Entities governed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 are required to comply with ADs issued by CASA. This includes aircraft operators, manufacturers, and maintenance providers, all of whom must adhere to the specific directives outlined in the ADs. These directives can include mandatory inspections, repairs, or modifications to aircraft to ensure they remain airworthy. Failure to comply with these directives can result in serious safety risks and potential regulatory action against the non-compliant entities.
Breaches of ADs can lead to significant consequences, both civil and criminal. Civil penalties can include fines, suspension of airworthiness certificates, and even grounding of non-compliant aircraft. Criminal penalties may apply for more severe breaches, potentially leading to imprisonment, particularly if the non-compliance results in a safety incident or accident. The exact penalties depend on the severity of the breach and are determined by the courts. The Civil Aviation Act 1988 and associated regulations emphasise the importance of adhering to ADs to maintain the highest safety standards in aviation.
