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/AA-1/10 affecting Grumman AA-1 series aircraft in 1972. 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 framework for the regulation of civil aviation in Australia, aiming to ensure the safety and efficiency of air navigation and the aviation industry. The Civil Aviation Safety Regulations 1998, which were made under the authority of the Act, include provisions for the issuance of airworthiness directives (ADs). ADs serve as a mechanism to address safety issues related to aircraft and aeronautical products, ensuring that they remain airworthy. The Civil Aviation Safety Regulations 1998 empower the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products, in accordance with international standards set by the International Civil Aviation Organization (ICAO). The objective of these regulations is to maintain and enhance the safety of air navigation, and the enactment of these ADs is in the interest of public safety and regulatory compliance. The authority to issue these directives is derived from the Act and implemented by CASA, which operates as the national airworthiness authority.
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) that mandate compliance with airworthiness requirements for specific kinds of aircraft or aeronautical products. These directives serve to maintain the safety of air navigation and are binding instruments under Australian law. The issuance of ADs aligns with international standards set forth in Annex 8 to the Convention on International Civil Aviation, which delineates the responsibilities of States of Design and States of Registry in ensuring the continuing airworthiness of aircraft. In this context, the State of Design is responsible for providing necessary information to maintain airworthiness, while the State of Registry, in this case CASA, must enforce these requirements domestically. For example, CASA issued AD/AA-1/10 for Grumman AA-1 series aircraft in 1972, but has since decided to cancel it, effective 17 January 2008, due to its redundancy as the safety concerns it addressed are now covered by another AD. The cancellation does not require public consultation or a Regulatory Impact Statement as it reduces the regulatory burden.
Key Provisions
The Civil Aviation Act 1988, supported by the Civil Aviation Safety Regulations 1998, provides the framework for the issuance and management of airworthiness directives (ADs). Section 98 of the Civil Aviation Act 1988 allows the Governor-General to create regulations for the safety of air navigation, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products (s. 39.001(5)). An AD is considered a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and as such, it is also a legislative instrument in accordance with section 6 of the Legislative Instruments Act 2003.
The obligations under the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 mandate that CASA, as Australia’s national airworthiness authority, must assess information provided by the State of Design and, if necessary, issue an Australian AD to enforce the requirements of the State of Design. This ensures that the continuing airworthiness of aircraft types registered in Australia is maintained. For instance, CASA issued AD/AA-1/10 for Grumman AA-1 series aircraft in 1972. Following a review, CASA decided to cancel this AD, effective from 17 January 2008, as the original unsafe condition it addressed is now covered by AD/GENERAL/74 Amendment 1. This decision was made under the authority of the Act by the Manager, Airframes in the Airworthiness Engineering Branch.
The consequences for breaching the provisions of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can be severe, involving both civil and criminal penalties. Failure to comply with an AD can result in severe penalties, including fines and imprisonment, as these directives are crucial for ensuring the safety of air navigation. The specific penalties for non-compliance are not detailed within the provided text but can generally be inferred to be substantial given the critical nature of airworthiness regulations. The legislative framework also ensures that the process for issuing and cancelling ADs is transparent and complies with relevant legislative requirements, including the need for disallowance and legislative instrument status.
