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/R44/18, Amendment 1, affecting Robinson R44 model helicopters, in 2006. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 10 April 2008. The original unsafe condition is now addressed by AD/R44/22 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 establish a regulatory framework that ensures the safety and efficiency of civil aviation in Australia. One of the key mechanisms through which this is achieved is the issuance of airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs, as legislative instruments, are essential tools for maintaining the continuing airworthiness of aircraft, as mandated by international standards set forth in Annex 8 to the Convention on International Civil Aviation. The Civil Aviation Safety Authority (CASA) issues these directives to ensure compliance with safety standards, thereby safeguarding the interests of the public and the aviation industry. The authority to issue ADs is derived from the powers granted to the Governor-General under section 98 of the Act, and these directives must be assessed and, if necessary, adopted by the State of Registry to maintain the airworthiness of aircraft registered in Australia.
Scope and Application
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, establishes the framework for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These regulations apply to all aircraft and aeronautical products within the Commonwealth of Australia, thereby affecting entities such as aircraft manufacturers, operators, and maintenance service providers. The ADs are intended to ensure the safety of air navigation and the continuing airworthiness of aircraft types. The authority to issue ADs under regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows CASA to mandate specific safety requirements, which, as disallowable instruments under the Acts Interpretation Act 1901, must adhere to the Legislative Instruments Act 2003. Notably, while the ADs are a form of legislative instrument, they do not typically require consultation with the public or a Regulatory Impact Statement, unless otherwise deemed necessary by the Office of Best Practice Regulation. The geographic reach of these regulations is national, aligning with international standards set by the International Civil Aviation Organization (ICAO). Any exclusions or thresholds specific to the application of ADs are determined on a case-by-case basis by CASA, in line with the safety imperatives dictated by the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation Act 1988, specifically section 98, grants the Governor-General the authority to enact regulations for the Act's purposes and the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 enables the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning types of aircraft or aeronautical products. These directives are considered legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. An AD is a regulatory tool issued by the State of Design to ensure the continuing airworthiness of aircraft types and is typically adopted by the State of Registry, which, in Australia's case, is CASA.
Entities governed by the Civil Aviation Act 1988, particularly CASA and aircraft operators, have specific obligations under the legislation and the associated regulations. CASA is responsible for assessing and, if necessary, issuing Australian ADs based on directives from the State of Design. Aircraft operators, on the other hand, must comply with all ADs applicable to their aircraft to ensure compliance with airworthiness standards. These obligations include adhering to any mandatory requirements, undertaking necessary maintenance or modifications, and maintaining records of compliance as stipulated by the ADs.
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 include provisions for penalties and consequences for non-compliance with ADs. Failure to adhere to the requirements of an AD can result in significant civil or criminal penalties, depending on the severity of the breach. Under the Civil Aviation Act 1988, CASA has the authority to enforce compliance through measures such as fines, suspension or revocation of airworthiness certificates, and other administrative actions. The maximum penalties for non-compliance can vary, but they are designed to ensure that all parties maintain high standards of airworthiness and safety in aviation operations.
CASA issued AD/R44/18, Amendment 1, in 2006 for Robinson R44 model helicopters. Following a review, CASA decided to cancel this directive, effective from 10 April 2008. The cancellation resulted from the unsafe condition being addressed by a newer AD, AD/R44/22 Amendment 1. No public consultation was required for this cancellation as it reduced the regulatory burden, and the Office of Best Practice Regulation determined that ADs do not necessitate a Regulatory Impact Statement. The cancellation was executed by the Manager, Airframes, in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A(2) of the Act.
