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/CESSNA 310/27, affecting Cessna 310 series aircraft in 1971. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 17 January 2008. No replacement AD is required, as the original unsafe condition is now addressed by AD/GENERAL/74 Amendment 1.
No consultation with the Australian public has taken place on this AD cancellation, because the cancellation results in a reduction of the regulatory burden. 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, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide a comprehensive legislative framework governing all aspects of civil aviation within Australia, addressing the need for robust safety regulations and oversight to protect public safety and national interests. The Act empowers the Governor-General to issue regulations in the interest of air navigation safety, which includes the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). The Civil Aviation Safety Regulations 1998, under regulation 39.001, allow CASA to issue ADs for specific types of aircraft or aeronautical products to ensure they remain airworthy. This legislative structure aims to maintain the highest safety standards in alignment with international obligations, particularly those outlined in Annex 8 to the Convention on International Civil Aviation, where the State of Design is tasked with the continuing airworthiness of aircraft types.
Scope and Application
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, outlines the framework under which airworthiness directives (ADs) are issued to ensure the safety of air navigation. Pursuant to section 98 of the Act, the Governor-General is empowered to create regulations that serve the interests of air navigation safety, with regulation 39.001 specifically enabling the Civil Aviation Safety Authority (CASA) to issue ADs for types of aircraft or aeronautical products. These ADs, as legislative instruments under the Legislative Instruments Act 2003, are intended to address safety issues and ensure that aircraft maintain their airworthiness throughout their operational life. CASA, as the national airworthiness authority, is tasked with the responsibility of assessing and, if necessary, issuing ADs in line with the requirements set by the State of Design, as per Annex 8 to the Convention on International Civil Aviation. The jurisdictional reach of these regulations is national, applying to all aircraft registered within Australia and ensuring compliance with international standards. There are no stated exclusions or exemptions in the issuance of these directives, which are crucial for maintaining the safety and airworthiness of aircraft operating within Australian airspace.
Key Provisions
The Civil Aviation Act 1988, supported by the Civil Aviation Safety Regulations 1998, provides a framework for ensuring the safety of air navigation through various regulatory mechanisms. Under section 98 of the Act, the Governor-General has the authority to issue regulations, and regulation 39.001 specifically empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. An AD is a legislative instrument, which is disallowable under section 46A of the Acts Interpretation Act 1901 and subject to the provisions of the Legislative Instruments Act 2003.
The obligations imposed by these regulations are primarily on CASA and the States of Design and Registry. CASA, as Australia's national airworthiness authority, must assess any ADs issued by States of Design that pertain to aircraft on the Australian Register. If deemed appropriate, CASA is required to issue corresponding Australian ADs to mandate the necessary requirements for ensuring the continuing airworthiness of those aircraft. The State of Design, meanwhile, holds the overarching responsibility for the continuing airworthiness of aircraft types and must provide essential information to the States of Registry. The State of Registry, in turn, is responsible for developing or adopting the necessary requirements to maintain the airworthiness of individual aircraft.
Failure to comply with an AD can result in serious consequences. Section 143 of the Civil Aviation Act 1988 stipulates that it is an offence to operate an aircraft in a manner that contravenes an AD, with penalties including fines and potential imprisonment. The specific penalties are detailed in the regulations and may vary based on the severity of the breach. For instance, under the Civil Aviation Regulations 1988, the maximum penalty for operating an aircraft in contravention of an AD could be significant, reflecting the gravity of compromising air safety. Additionally, CASA has the authority to take enforcement actions, which can include grounding non-compliant aircraft or imposing operational restrictions until the necessary compliance measures are implemented.
