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 Civil Aviation Safety Authority or its predecessors issued AD/ROCK-114/7 affecting Gulfstream (Rockwell) 114 model aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/ROCK-114/7. The cancellation will become effective on 25 September 2008. No replacement AD is required, as the unsafe condition no longer exists.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, no consultation with the Australian public has taken place on this AD cancellation. 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 and New Technologies, in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 is a pivotal piece of legislation enacted to regulate civil aviation within Australia, ensuring the safety of air navigation as its primary objective. This Act provides the authority for the Governor-General to make regulations under section 98, thereby enabling the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. These directives are integral to maintaining the continuing airworthiness of aircraft and aeronautical products, and are designed in compliance with Annex 8 of the Convention on International Civil Aviation, which designates the State of Design as responsible for an aircraft type’s airworthiness. The Civil Aviation Act 1988 thus addresses the need for a robust regulatory framework that ensures aircraft safety and aligns with international standards. CASA, as Australia’s national airworthiness authority, plays a crucial role in assessing and issuing these directives, ensuring that they meet the highest safety standards.
Scope and Application
The Civil Aviation Act 1988 and its associated Civil Aviation Safety Regulations 1998 provide the framework for the issuance of airworthiness directives (ADs) in Australia, with the Civil Aviation Safety Authority (CASA) being the primary body responsible for ensuring the continuing airworthiness of aircraft registered in Australia. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers CASA to issue ADs for specific types of aircraft or aeronautical products to address safety concerns, and these directives are considered legislative instruments under section 6 of the Legislative Instruments Act 2003. The ADs serve as a critical mechanism for the continuing airworthiness of aircraft types, aligning with obligations under Annex 8 of the Convention on International Civil Aviation, which designates the State of Design as responsible for the continuing airworthiness of aircraft types. The State of Registry, in this case CASA, must then ensure that these directives are appropriately implemented to maintain safety standards. The AD/ROCK-114/7 concerning Gulfstream (Rockwell) 114 model aeroplanes, initially issued by CASA, has been subsequently cancelled by CASA due to the resolution of the safety issue it addressed, reflecting Australia's adherence to international obligations and the continuous reassessment of safety requirements.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legislative framework for the issuance of airworthiness directives (ADs) in Australia. According to section 98 of the Act, the Governor-General may make regulations in the interests of air navigation safety, and under regulation 39.001 of the Regulations, CASA is authorised to issue ADs for specific types of aircraft or aeronautical products. These ADs serve as legal instruments, as outlined in subregulation 39.001(5) and section 46A of the Acts Interpretation Act 1901, and are recognised as legislative instruments under section 6 of the Legislative Instruments Act 2003. Such ADs are instrumental in ensuring the continuing airworthiness of aircraft as mandated by Annex 8 to the Convention on International Civil Aviation, which places the responsibility on the State of Design to provide necessary information to appropriate States of Registry.
Under the Civil Aviation Safety Regulations, the State of Registry is obligated to develop or adopt requirements to ensure the continuing airworthiness of aircraft within its jurisdiction. This means that when the State of Design issues an AD for a type of aircraft registered in Australia, CASA, as the national airworthiness authority, is required to assess this information. If deemed necessary, CASA must then issue an Australian AD to mandate the requirements of the State of Design. This process ensures that the safety standards and regulations are consistently applied across different jurisdictions, aligning with international standards and practices.
Failure to comply with an AD can lead to severe consequences. Non-compliance may result in the aircraft being grounded, which could prevent it from being operated until the required safety measures are implemented. Furthermore, individuals or entities found in breach of an AD may face significant penalties, including fines and imprisonment, as stipulated in the applicable sections of the Civil Aviation Act 1988 and other related legislation. The specific penalties can vary depending on the severity of the breach and the regulatory context.
In the case of AD/ROCK-114/7, which affected Gulfstream (Rockwell) 114 model aeroplanes, CASA issued and subsequently cancelled the Australian AD following an assessment. The cancellation was effective from 25 September 2008, with no replacement AD needed as the unsafe condition no longer existed. Given that this cancellation was due to Australia's obligations under the Convention on International Civil Aviation, no public consultation was required, and the Office of Best Practice Regulation determined that a Regulatory Impact Statement was not necessary. The AD was issued by the Manager, Systems and New Technologies, in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A(2) of the Act.
