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/BELL 205/23 Amendment 4, affecting Bell 205 model helicopters in 1988. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 14 February 2008. No replacement AD is required, as the technical requirements are now included in the helicopter maintenance manuals.
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 legislative framework for the regulation of civil aviation in Australia, ensuring safety and efficiency in air navigation. This Act empowers the Governor-General to make regulations for the purposes of the Act, with a primary focus on the safety of air navigation. One such regulation is the Civil Aviation Safety Regulations 1998, which allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are essential for maintaining the continuing airworthiness of aircraft and are considered legislative instruments under the Legislative Instruments Act 2003. The policy objective of these regulations is to align with international standards, particularly those outlined in Annex 8 to the Convention on International Civil Aviation, ensuring that Australia meets its obligations to other ICAO Contracting States.
Scope and Application
The Civil Aviation Act 1988, as amended by the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products under regulation 39.001. These ADs are legislative instruments and are essential for maintaining the continuing airworthiness of aircraft, in accordance with Annex 8 to the Convention on International Civil Aviation. The State of Design and the State of Registry bear responsibilities for ensuring that aircraft remain airworthy, with CASA acting as Australia's national airworthiness authority to enforce these requirements. In the case of Bell 205 model helicopters, CASA issued AD/BELL 205/23 Amendment 4 in 1988; however, following a review, CASA has decided to cancel this directive, effective 14 February 2008. This cancellation reflects the integration of technical requirements into helicopter maintenance manuals, reducing regulatory burden without the need for public consultation or a Regulatory Impact Statement. The AD cancellation was authorised by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in line with the provisions of the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation Act 1988, in particular section 98, empowers the Governor-General to enact regulations aimed at ensuring the safety of air navigation. This legislative authority is exercised through the Civil Aviation Safety Regulations 1998, specifically regulation 39.001, which authorises the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. An AD, as clarified in subregulation 39.001(5), is considered a disallowable instrument under section 46A of the Acts Interpretation Act 1901 and is thus a legislative instrument as per section 6 of the Legislative Instruments Act 2003.
These airworthiness directives are vital for maintaining the continuing airworthiness of aircraft types, as outlined in Annex 8 to the Convention on International Civil Aviation. The State of Design, which is responsible for the aircraft type, must provide necessary information to ensure its airworthiness, and this information is typically communicated through ADs. In Australia, CASA, acting as the national airworthiness authority, must review and, if necessary, issue Australian ADs to enforce the requirements of the State of Design. For instance, CASA issued AD/BELL 205/23 Amendment 4 for Bell 205 model helicopters in 1988, which has now been cancelled due to the incorporation of these technical requirements into helicopter maintenance manuals.
The obligations under the Act and regulations require CASA to assess and respond to ADs issued by the State of Design. CASA must ensure that the continuing airworthiness of aircraft registered in Australia is maintained through the issuance of appropriate ADs. The State of Registry is also obligated to develop or adopt requirements to ensure the continuing airworthiness of aircraft, aligning with the directives issued by CASA. This ensures a coordinated approach to airworthiness maintenance, aligning with international standards and practices.
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 do not explicitly detail specific offences, penalties, or consequences for non-compliance with ADs. However, failure to comply with ADs can lead to significant safety risks and potential legal consequences under other provisions of the Act. CASA has the authority to take enforcement actions against non-compliance, which can include fines, suspension or revocation of aircraft certificates, and other regulatory measures to ensure compliance and maintain safety standards.
