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 205/8 Amdt 1 affecting Cessna 205 model aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/CESSNA 205/8 Amdt 1. 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 was enacted to provide a framework for the regulation of civil aviation in Australia, aiming to ensure the safety of air navigation and the continuing airworthiness of aircraft. The Act empowers the Governor-General to make regulations for these purposes, as demonstrated in the Civil Aviation Safety Regulations 1998, which authorise the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These ADs serve as a means to maintain the safety standards for aircraft and aeronautical products, aligning with international obligations under the Convention on International Civil Aviation, particularly Annex 8 which mandates that the State of Design provides necessary information for continuing airworthiness. The Civil Aviation Safety Regulations 1998 specify that ADs are legislative instruments subject to disallowance under the Acts Interpretation Act 1901. The legislative process for issuing ADs, including the recent cancellation of AD/CESSNA 205/8 Amdt 1 for Cessna 205 model aeroplanes by CASA, is governed by the Act and involves internal assessments without the need for public consultation or a Regulatory Impact Statement.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) to ensure the safety of air navigation. These directives apply to specific kinds of aircraft or aeronautical products, and under regulation 39.001(5) of the Civil Aviation Safety Regulations 1998, ADs are classified as disallowable instruments, thereby being legislative instruments. The ADs are integral to maintaining the continuing airworthiness of aircraft, a responsibility that rests with the State of Registry under Annex 8 to the Convention on International Civil Aviation. The State of Design, meanwhile, bears the overall responsibility for ensuring the airworthiness of an aircraft type. CASA, acting in accordance with Australia's international obligations, has the authority to issue these directives, as demonstrated by the issuance and subsequent cancellation of AD/CESSNA 205/8 Amdt 1 affecting Cessna 205 model aeroplanes. The cancellation of this specific AD, which took effect on 25 September 2008, was due to the resolution of the unsafe condition it was designed to address, and no public consultation or Regulatory Impact Statement was required for this action. The issuance of such directives is a critical function of CASA, overseen by the Manager, Airframe and Structures, within the Airworthiness Engineering Group, in alignment with the statutory provisions outlined in the Act.
Key Provisions
The main operative sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 pertain to the issuance of airworthiness directives (ADs) (sections 98, 39.001, 39.001(5)). Section 98 allows the Governor-General to make regulations for the purposes of the Act, focusing on the safety of air navigation. Regulation 39.001 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products. Subregulation 39.001(5) clarifies that ADs are disallowable instruments under the Acts Interpretation Act 1901 and, therefore, legislative instruments under the Legislative Instruments Act 2003. These provisions collectively ensure that ADs are a formal means to address continuing airworthiness concerns in compliance with international standards.
The Civil Aviation Safety Regulations 1998 impose obligations on CASA and other entities to ensure the safety and airworthiness of aircraft. CASA, as the regulatory authority, must issue ADs when necessary to address safety issues related to aircraft or aeronautical products. The State of Design, as per Annex 8 to the Convention on International Civil Aviation, has the primary responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to the States of Registry. The State of Registry, in turn, must develop or adopt requirements to ensure the continuing airworthiness of individual aircraft. These obligations ensure a coordinated approach to maintaining the safety and airworthiness of aircraft both domestically and internationally.
There are no specific offences, penalties, or civil/criminal consequences mentioned for the breach of ADs within the provided text. However, the issuance and enforcement of ADs are critical regulatory tools that, if not complied with, could lead to significant safety risks and potential legal ramifications. Failure to adhere to ADs might result in penalties under other sections of the Civil Aviation Act 1988 or related regulations, which could include fines, enforcement actions, or other regulatory sanctions. The specific penalties for non-compliance would depend on the nature and severity of the breach, as well as the provisions of other relevant legislation.
