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/BEA 121/12 affecting Beagle A.121 (Pup) 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 regulate civil aviation in Australia, ensuring the safety and efficiency of air navigation, amongst other objectives. The Act provides the legislative framework under which the Civil Aviation Safety Regulations 1998 were created, including the authority for the issuance of airworthiness directives. These directives are crucial for maintaining the continuing airworthiness of aircraft and aeronautical products, in line with international standards set by the International Civil Aviation Organization (ICAO). The Civil Aviation Safety Regulations 1998 specify that the Civil Aviation Safety Authority (CASA) can issue these directives, which are considered legislative instruments under the Acts Interpretation Act 1901. The policy objective is to enhance aviation safety by ensuring that aircraft meet specific safety standards, aligning with the responsibilities of the State of Design and the State of Registry as outlined in Annex 8 of the Convention on International Civil Aviation.
Scope and Application
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, establishes a framework for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). Under this legislative framework, CASA, as Australia's national airworthiness authority, is empowered to issue ADs for specific kinds of aircraft or aeronautical products in order to ensure the safety of air navigation. The issuance of ADs is mandated by regulation 39.001 of the Civil Aviation Safety Regulations 1998 and, according to subregulation 39.001(5), these directives are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, thereby qualifying them as legislative instruments. The ADs are a critical component of the international continuing airworthiness information system, as per Annex 8 to the Convention on International Civil Aviation, where the State of Design is responsible for providing necessary information to States of Registry to maintain aircraft airworthiness. The State of Registry, in this case CASA, must then ensure the ongoing airworthiness of the aircraft registered within its jurisdiction. This framework applies to all aircraft registered in Australia, and to the entities responsible for their maintenance and operation. The legislation does not specify exclusions or exemptions but mandates the assessment and potential issuance of ADs to align with international standards and to mitigate any identified unsafe conditions.
Key Provisions
The key sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 (CASR) provide the legislative framework for the issuance and management of airworthiness directives (ADs). Under section 98 of the Act, the Governor-General can make regulations for air navigation safety, and regulation 39.001 of the CASR allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products. Section 39.001(5) further clarifies that ADs are legislative instruments that can be disallowed under section 46A of the Acts Interpretation Act 1901.
The Act and Regulations impose several obligations on the parties they govern. For instance, 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 State of Registry. The State of Registry, in turn, must develop or adopt requirements to ensure the continuing airworthiness of individual aircraft registered within its jurisdiction. CASA, as Australia’s national airworthiness authority, must assess any AD issued by a State of Design and, if necessary, issue a corresponding Australian AD to mandate the requirements. This process ensures that all relevant safety measures are effectively communicated and enforced.
In terms of consequences for breaches, the Act and Regulations do not explicitly detail specific offences or penalties related to the issuance or non-compliance with ADs. However, the broader context of aviation law implies that non-compliance with ADs could result in significant civil or criminal consequences, including fines, imprisonment, or both, depending on the severity of the breach and the specific regulations involved. CASA has the authority to enforce compliance and take appropriate action against entities or individuals who fail to adhere to the requirements set forth in ADs.
The legislative process for issuing ADs, as seen in the case of AD/BEA 121/12 affecting Beagle A.121 (Pup) series aircraft, involves thorough review and assessment by CASA. In this instance, CASA decided to cancel the AD, effective from 17 January 2008, because the original unsafe condition was now addressed by another directive. The cancellation was made in accordance with subsection 84A(2) of the Act, without the need for public consultation as it was determined to reduce the regulatory burden. Additionally, the Office of Best Practice Regulation has assessed that ADs do not require a Regulatory Impact Statement, further streamlining the process.
