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/CESSNA 400/27, affecting Cessna 400 series aircraft in 1971. 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, enacted by the Australian Parliament, serves to regulate civil aviation activities and ensure safety within the sector. This legislation provides the framework for the creation of regulations to safeguard air navigation, one of which is the Civil Aviation Safety Regulations 1998. Specifically, section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations in the interests of air navigation safety, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are legislative instruments under the Legislative Instruments Act 2003. The objective of these regulations is to ensure the continuing airworthiness of aircraft types, with the State of Design having primary responsibility under Annex 8 to the Convention on International Civil Aviation, and the State of Registry tasked with ensuring the airworthiness of individual aircraft. The recent decision by CASA to cancel AD/CESSNA 400/27, affecting Cessna 400 series aircraft, demonstrates the dynamic nature of airworthiness regulation, aimed at maintaining safety standards and reducing regulatory burden.
Scope and Application
The Civil Aviation Safety Regulations 1998, made under the authority of the Civil Aviation Act 1988, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs serve to ensure the continuing airworthiness of aircraft registered in Australia, aligning with international standards as outlined in Annex 8 to the Convention on International Civil Aviation. The State of Design, which is responsible for the overall airworthiness of an aircraft type, must provide necessary information to the States of Registry to maintain compliance with safety standards. CASA, as Australia's national airworthiness authority, must review and, if necessary, issue Australian ADs to mandate the requirements specified by the State of Design. For instance, CASA issued and subsequently cancelled AD/CESSNA 400/27 for Cessna 400 series aircraft, with the cancellation becoming effective on 17 January 2008, as the original safety concerns are now addressed by another AD. This process does not require public consultation or a Regulatory Impact Statement, as it reduces the regulatory burden and ensures that the safety requirements are effectively managed.
Key Provisions
The Civil Aviation Act 1988, specifically under section 98, grants the Governor-General the authority to establish regulations aimed at ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 further empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. These ADs serve as legal instruments for ensuring the continued airworthiness of aircraft, as mandated by Annex 8 to the Convention on International Civil Aviation. Subregulation 39.001(5) confirms that ADs are disallowable instruments under section 46A of the Acts Interpretation Act 1901, thereby classifying them as legislative instruments in accordance with section 6 of the Legislative Instruments Act 2003.
The obligations imposed by the Act and its regulations include ensuring that the State of Design, which is responsible for the continuing airworthiness of a particular aircraft type, provides necessary information to the appropriate State of Registry. The State of Registry, in turn, must establish or adopt regulations to maintain the airworthiness of aircraft registered within its jurisdiction. When the State of Design issues an AD for a type of aircraft registered in Australia, CASA, as the national airworthiness authority, is tasked with evaluating this information and, if necessary, issuing an Australian AD to enforce the requirements stipulated by the State of Design. This collaborative approach ensures that all aircraft operating in Australian airspace meet the highest safety standards.
In the case of AD/CESSNA 400/27, CASA issued an AD affecting Cessna 400 series aircraft in 1971. After a thorough review, CASA has decided to cancel this AD, effective 17 January 2008, as the original safety issue it addressed has since been resolved by another AD. The cancellation of AD/CESSNA 400/27 does not necessitate a replacement AD because the underlying safety concern is now covered by AD/GENERAL/74 Amendment 1. The decision to cancel the AD was made without public consultation, as the cancellation reduces the regulatory burden, and the Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement. The AD was issued by the Manager, Airframes, in the Airworthiness Engineering Branch of CASA, in accordance with subsection 84A(2) of the Act.
The Civil Aviation Safety Regulations 1998 outline various consequences for non-compliance with ADs. Failure to adhere to an AD can result in severe penalties, including fines and potential criminal charges. The specific penalties can vary depending on the severity of the violation and the circumstances surrounding the non-compliance. It is crucial for aircraft operators, maintenance personnel, and other stakeholders to comply with ADs to ensure the ongoing safety and airworthiness of aircraft. Non-compliance not only risks safety but also legal repercussions that can have significant implications for individuals and organisations involved in civil aviation.
