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.
CASA issued AD/R22/24, affecting Robinson R22 helicopters. Amendment 1 of this AD was in response to the information in the AD being incorporated in the aircraft maintenance manual. Following that incorporation into the aircraft manual, the manufacturer revised the data. As a result of that revision a review of the AD was conducted and it was determined that the unsafe condition detailed in the AD was being adequately addressed by the latest revision of the manufacturers maintenance manual. CASA has determined that AD/R22/24 Amendment 1 will be cancelled with an effective date of 26 October 2006.
The AD has been made by the Manager, Airframes/New Technologies and Systems, in the Manufacturing, Certification and New Technologies Office, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Commonwealth Parliament, addresses the overarching framework for civil aviation within Australia, with a primary focus on ensuring the safety of air navigation. This legislation empowers the Governor-General to create regulations that contribute to air navigation safety, including the issuance of airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. The policy objective underpinning the Act is to maintain the highest possible safety standards in civil aviation, ensuring that all aircraft and aeronautical products operate within safe parameters. The Act’s provisions facilitate the implementation of ADs, which are legislative instruments that mandate specific actions to address safety concerns, in alignment with international standards set by the International Civil Aviation Organization (ICAO). These ADs play a crucial role in ensuring the continuing airworthiness of aircraft, with the Civil Aviation Safety Authority (CASA) acting as the national airworthiness authority responsible for issuing and enforcing these directives.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 apply to various entities and individuals involved in civil aviation within Australia. Under regulation 39.001, the Civil Aviation Safety Authority (CASA) has the authority to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products, which are considered legislative instruments as per the Legislative Instruments Act 2003. These ADs are crucial for ensuring the continuing airworthiness of aircraft as stipulated under Annex 8 to the Convention on International Civil Aviation. The State of Design and the State of Registry both play significant roles in this regulatory framework, with the former responsible for providing necessary information to ensure airworthiness and the latter tasked with developing or adopting requirements to maintain airworthiness. CASA, acting on behalf of Australia, assesses information from the State of Design and issues Australian ADs to enforce these requirements. An example of this process is evident in AD/R22/24, which was issued for Robinson R22 helicopters. After a revision by the manufacturer, it was determined that the unsafe condition detailed in the AD was adequately addressed by the latest revision of the maintenance manual, leading to the cancellation of AD/R22/24 Amendment 1 effective from 26 October 2006. This act of issuing and amending ADs demonstrates the jurisdictional reach of the Civil Aviation Act and the Civil Aviation Safety Regulations, ensuring compliance and safety in civil aviation.
Key Provisions
The Civil Aviation Act 1988, as amended by the Civil Aviation Safety Regulations 1998, enables the issuance of airworthiness directives (ADs) to ensure the safety of aircraft and aeronautical products. Section 98 of the Act allows the Governor-General to make regulations for the safety of air navigation, while regulation 39.001 provides the Civil Aviation Safety Authority (CASA) with the authority to issue ADs. These ADs are legislative instruments under section 6 of the Legislative Instruments Act 2003. Additionally, Annex 8 of the Convention on International Civil Aviation mandates that the State of Design (the country where the aircraft is designed) must ensure the continuing airworthiness of the aircraft type, and provide necessary information to the States of Registry.
The obligations imposed by these provisions include the responsibility of the State of Design to provide ongoing airworthiness information and the requirement for the State of Registry to ensure the continuing airworthiness of individual aircraft. In the context of Australia, CASA must assess any ADs issued by the State of Design and, if necessary, issue corresponding Australian ADs. This ensures that Australian registered aircraft comply with international safety standards. For instance, CASA issued AD/R22/24 concerning Robinson R22 helicopters, which was later amended and subsequently cancelled following revisions by the manufacturer and a review that found the safety concerns were adequately addressed in the updated maintenance manual.
Breaches of these provisions can lead to civil and criminal consequences. If an operator fails to comply with an AD, they may face enforcement actions by CASA. Civil penalties for non-compliance can include fines, while more severe breaches may lead to criminal charges. The maximum penalties for breaches can vary, but they are intended to ensure strict adherence to safety regulations. For example, under section 84A(2) of the Act, CASA has the authority to enforce compliance and impose penalties on those who do not adhere to the mandated airworthiness requirements.
