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/R22/51, affecting Robinson R22 series helicopters, in 2004. The FAA is the State of Design for the R22 type. As a result of a request from industry, CASA has amended the Australian AD to clarify that a once-only magnetic particle non-destructive test on the coupling is required. The amended AD, AD/R22/51 Amendment 2, will become effective on 27 October 2005. This AD cancels and replaces the previous issue.
The Office of Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, New Technologies and Systems, in the Manufacturing, Certification and New Technologies Office, 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 regulation of civil aviation in Australia, aiming to ensure the safety and efficiency of air navigation. The Act empowers the Governor-General to make regulations necessary for the purposes of the Act and in the interests of air navigation safety. Under the authority granted by the Civil Aviation Act, the Civil Aviation Safety Regulations 1998 were established, which include provisions for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These regulations reflect international standards set by the International Civil Aviation Organization (ICAO), particularly Annex 8, which mandates that the State of Design must maintain and provide information to ensure the continuing airworthiness of aircraft types. CASA, as Australia’s national airworthiness authority, has the responsibility to assess this information and issue ADs as necessary to maintain safety standards in line with international obligations.
Scope and Application
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives are legislative instruments, subject to disallowance as per the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The application of these ADs is integral to ensuring the continuing airworthiness of aircraft, aligning with the responsibilities outlined in Annex 8 to the Convention on International Civil Aviation, where the State of Design and the State of Registry have defined roles in maintaining aircraft safety standards. CASA, as Australia’s national airworthiness authority, is tasked with issuing Australian ADs when necessary, following the issuance of ADs by the State of Design. This legislative framework applies to all aircraft registered in Australia and is influenced by international standards and requirements, ensuring a cohesive approach to aviation safety across jurisdictions. The ADs are designed to address specific safety concerns or maintenance requirements, and any amendments, such as those made to AD/R22/51 for Robinson R22 series helicopters, are intended to enhance safety without necessitating a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Safety Regulations 1998 under section 39.001 empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. Section 39.001(5) of the same regulations stipulates that an AD is a disallowable instrument, thus classifying it as a legislative instrument under section 6 of the Legislative Instruments Act 2003. This legislative framework ensures that ADs serve as a critical tool for maintaining the continuing airworthiness of aircraft, aligning with Annex 8 to the Convention on International Civil Aviation. Specifically, ADs are the primary mechanism by which States of Design provide necessary information to States of Registry to ensure that aircraft remain airworthy.
The obligations imposed by these regulations are significant. The State of Design, such as the Federal Aviation Administration (FAA) for the Robinson R22 type, is responsible for issuing ADs that include safety-critical information. CASA, as Australia’s national airworthiness authority, must then assess this information and, if necessary, issue corresponding Australian ADs to mandate the required actions. For example, CASA issued AD/R22/51 in 2004, which has now been amended to include a specific requirement for a once-only magnetic particle non-destructive test on the coupling of Robinson R22 series helicopters. Such amendments ensure that the ADs remain current and reflect the latest safety standards.
Failing to comply with an AD can lead to severe consequences. Under the Civil Aviation Act 1988, non-compliance with an airworthiness directive can result in civil penalties. The Act does not specify maximum penalties but provides that CASA can take enforcement action, including the possibility of grounding non-compliant aircraft. Additionally, operators found to be in violation of ADs may face prosecution, which could lead to criminal penalties if the non-compliance is deemed to have endangered safety. The seriousness of these consequences underscores the importance of adhering to ADs to maintain the safety and airworthiness of aircraft.
