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
The Civil Aviation Safety Authority or its predecessors issued AD/CESSNA 177/15 affecting Cessna 177, 177RG and F177RG model aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/CESSNA 177/15. 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, Airframe and Structures, in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Parliament of Australia, was established to regulate civil aviation and ensure the safety of air navigation. It provides the framework within which the Civil Aviation Safety Regulations 1998 operate, including the issuance of airworthiness directives (ADs). These ADs are legislative instruments used to address safety concerns related to specific types of aircraft or aeronautical products, thereby ensuring compliance with international standards set by the Convention on International Civil Aviation. The Civil Aviation Safety Authority (CASA) issues these ADs in accordance with Annex 8 of the Convention, which stipulates that the State of Design is responsible for the continuing airworthiness of an aircraft type, while the State of Registry ensures the airworthiness of individual aircraft. The ADs serve as a crucial mechanism for disseminating continuing airworthiness information, and their issuance and cancellation are integral to maintaining safety standards in civil aviation.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, encompasses various provisions designed to ensure the safety of air navigation in Australia. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specified types of aircraft or aeronautical products. These ADs, which are legislative instruments under the Legislative Instruments Act 2003, play a crucial role in maintaining the continuing airworthiness of aircraft as required by Annex 8 to the Convention on International Civil Aviation. The State of Registry of an individual aircraft, in alignment with international obligations, is tasked with ensuring the ongoing airworthiness of the aircraft, which involves adhering to the ADs issued by CASA. The Act and associated regulations apply to all relevant aircraft and aeronautical products within Australia, and CASA’s authority extends to the issuance and cancellation of ADs to mitigate safety risks. The recent cancellation of AD/CESSNA 177/15, which affected Cessna 177, 177RG, and F177RG model aeroplanes, exemplifies how CASA enforces these safety measures in response to the evolving safety landscape.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a framework for the issuance of airworthiness directives (ADs) under section 98 of the Act and regulation 39.001 of the Regulations (39.001(5)). ADs are legislative instruments that ensure the safety of aircraft by addressing specific safety concerns related to certain types or models of aircraft. They are issued by the Civil Aviation Safety Authority (CASA) and are governed by the oversight responsibilities of the State of Design and the State of Registry as outlined in Annex 8 of the Convention on International Civil Aviation. The State of Design must provide necessary information to ensure the continuing airworthiness of an aircraft type, while the State of Registry must implement or adopt requirements to ensure the airworthiness of individual aircraft.
Compliance with ADs is mandatory for all parties involved in the operation, maintenance, or certification of affected aircraft. Owners, operators, and maintenance providers must adhere to the requirements outlined in the ADs, which may include specific maintenance actions, operational limitations, or modifications to ensure the safety of the aircraft. CASA is responsible for issuing and enforcing ADs to maintain the highest safety standards in the aviation industry. Failure to comply with ADs can result in severe consequences, including potential grounding of the aircraft, revocation of airworthiness certificates, and enforcement actions against non-compliant entities.
Breach of ADs may result in both civil and criminal penalties. Under section 84A of the Act, CASA has the authority to impose administrative penalties for non-compliance with ADs. The maximum penalty for individuals is a fine of up to $22,200 or imprisonment for up to 12 months, or both, while the maximum penalty for corporations is significantly higher, reaching up to $1,110,000. Additionally, the non-compliance with ADs may also lead to criminal charges, resulting in more severe penalties depending on the nature and extent of the breach. CASA can take enforcement actions, including the issuance of compliance notices, investigations, and legal proceedings, to ensure adherence to ADs and to address any safety concerns arising from non-compliance.
