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/HU 269/91 affecting Schweizer (Hughes) 269 series Helicopters. CASA has assessed this AD and as a result has cancelled Australian AD/HU 269/91. The cancellation will become effective on 7 May 2009. 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 was enacted to provide for the safety and efficiency of civil aviation in Australia, and to establish the Civil Aviation Safety Authority (CASA) as the national airworthiness authority. One of its key provisions is section 98, which empowers the Governor-General to make regulations for the purposes of the Act, with a focus on ensuring the safety of air navigation. This Act was introduced to address the need for comprehensive regulation of civil aviation in Australia, aiming to maintain high safety standards and ensure the orderly development of air transport. The Civil Aviation Safety Regulations 1998, made under this Act, further detail the regulatory framework, including the issuance of airworthiness directives by CASA to maintain the continuing airworthiness of aircraft. The objective is to align Australian regulations with international standards and obligations under the Convention on International Civil Aviation. The regulations were enacted by the Australian Parliament, reflecting the government's commitment to upholding stringent safety and operational standards in the aviation sector.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. These ADs are mandated to ensure the safety of air navigation, aligning with the obligations of the State of Design and State of Registry under Annex 8 of the Convention on International Civil Aviation. CASA, as Australia's national airworthiness authority, is required to assess information from the State of Design and, if necessary, issue Australian ADs to enforce the requisite airworthiness measures. This regulatory framework ensures that the continuing airworthiness of aircraft registered in Australia is maintained in accordance with international standards. The issuance and cancellation of ADs, such as the cancellation of AD/HU 269/91 for Schweizer (Hughes) 269 series helicopters, are legislative instruments governed by the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The specific AD cancellations are made without public consultation as they fall outside the need for a Regulatory Impact Statement, reflecting the authority’s adherence to international obligations and domestic legislative mandates.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 outline key provisions for the issuance of airworthiness directives (ADs). Section 98 of the Act allows the Governor-General to make regulations for air navigation safety, while regulation 39.001 of the Regulations empowers CASA to issue ADs for specific types of aircraft or aeronautical products. This process is further clarified by subregulation 39.001(5), which establishes that an AD is a disallowable instrument and thus a legislative instrument under the Acts Interpretation Act 1901. Under Annex 8 to the Convention on International Civil Aviation, the State of Design has the primary responsibility for ensuring 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 continuing airworthiness, and CASA must assess and, if appropriate, issue an Australian AD to enforce these requirements.
Entities governed by these regulations, particularly CASA and States of Registry, are mandated to follow a structured process for the issuance and implementation of ADs. This includes assessing information from the State of Design and issuing Australian ADs as necessary to maintain safety standards. Furthermore, these entities must ensure compliance with international obligations under the Convention on International Civil Aviation, ensuring that all ADs issued are in line with the continuing airworthiness requirements set forth by ICAO Contracting States. This systematic approach ensures that aircraft remain airworthy and meet international safety standards.
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 also outline the consequences for non-compliance with ADs. Entities that fail to comply with ADs may face serious legal and financial repercussions. While the specific civil or criminal penalties are not detailed in the given text, it is understood that non-compliance could result in significant sanctions under the broader framework of the Act and associated regulations. For instance, penalties might include fines or imprisonment, depending on the severity of the breach and the specific provisions of the Act. The regulatory framework ensures that all parties adhere to stringent safety standards, with potential severe consequences for failure to do so.
