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 206/91 Amendment 1, affecting Bell 206 model helicopters in 2003. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 31 July 2008. No replacement AD is required, as the inspections required by this AD are now included in the helicopter maintenance manual.
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 establish a comprehensive regulatory framework for civil aviation in Australia, addressing the need for safety standards and regulatory oversight in the aviation industry. This Act empowers the Governor-General to make regulations that ensure the safety of air navigation, with a particular focus on airworthiness. One significant regulation under this Act is the Civil Aviation Safety Regulations 1998, which permit the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs). ADs are legislative instruments that mandate requirements to ensure the continuing airworthiness of aircraft, aligning with international standards as set out in Annex 8 to the Convention on International Civil Aviation. CASA, as Australia's national airworthiness authority, is tasked with assessing and implementing ADs issued by the State of Design, ensuring they meet Australian safety standards. The authority to issue and cancel ADs is exercised under the auspices of the Act to maintain and enhance aviation safety within Australia.
Scope and Application
The Civil Aviation Act 1988 and its associated regulations, including the Civil Aviation Safety Regulations 1998, empower 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 are governed under regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs are considered legislative instruments, disallowable under section 46A of the Acts Interpretation Act 1901, and are subject to scrutiny under the Legislative Instruments Act 2003. ADs are integral to maintaining the continuing airworthiness of aircraft types, a responsibility primarily held by the State of Design, while States of Registry, such as CASA in Australia, are tasked with ensuring compliance and issuing relevant ADs within their jurisdiction. The application of these regulations is not limited to Australia but aligns with international standards set by the International Civil Aviation Organization (ICAO). The recent cancellation of AD/BELL 206/91 Amendment 1 for Bell 206 model helicopters reflects CASA’s commitment to aligning regulatory practices with evolving maintenance standards and reducing unnecessary regulatory burdens, as no replacement AD is deemed necessary.
Key Provisions
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, lays down a framework for the regulation of aviation safety in Australia. Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to create regulations for air navigation safety. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning types of aircraft or aeronautical products. According to subregulation 39.001(5), an AD is considered a disallowable instrument under section 46A of the Acts Interpretation Act 1901 and is treated as a legislative instrument pursuant to section 6 of the Legislative Instruments Act 2003.
Under the obligations outlined in these regulations, CASA must act on information from the State of Design, which has primary responsibility for the continuing airworthiness of an aircraft type. Annex 8 of the Convention on International Civil Aviation requires the State of Design to provide necessary information to ensure the aircraft's airworthiness. The State of Registry, which is responsible for the individual aircraft's continuing airworthiness, must develop or adopt requirements to ensure the aircraft remains airworthy. If a State of Design issues an AD for an aircraft type registered in Australia, CASA must assess this information and, if necessary, issue an Australian AD to enforce the State of Design's requirements.
CASA's authority to issue ADs is exercised through a formal process, as demonstrated in the case of AD/BELL 206/91 Amendment 1, which affected Bell 206 model helicopters. CASA reviewed this AD and decided to cancel it, effective from 31 July 2008. The cancellation was made because the inspections required by this AD are now included in the helicopter maintenance manual. Given that the cancellation reduces the regulatory burden, no public consultation was necessary, and the Office of Best Practice Regulation determined that ADs do not require a Regulatory Impact Statement. The AD was issued by the Manager, Airframes in the Airworthiness Engineering Branch on behalf of CASA, in accordance with subsection 84A(2) of the Act.
There are specific consequences for non-compliance with ADs. Any breach of an AD can result in severe civil or criminal penalties. The severity of these penalties can vary, depending on the nature and extent of the non-compliance. CASA enforces these regulations rigorously to maintain the high safety standards required in the aviation industry.
