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/BEECH 56/20, affecting Beech 56 model aircraft in 1980. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 5 June 2008. No replacement AD is required, as all affected aircraft would have been inspected, and, if necessary, modified long ago.
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 legislative framework governing civil aviation in Australia, with a primary focus on ensuring the safety of air navigation. This Act empowers the Governor-General to make regulations for the safety of air navigation, including the issuance of airworthiness directives (ADs) under the Civil Aviation Safety Regulations 1998. These regulations mandate that ADs, which are legislative instruments, are issued to ensure the continuing airworthiness of aircraft types and aeronautical products. The Civil Aviation Safety Authority (CASA) issues such directives in accordance with international standards set forth by the Convention on International Civil Aviation, specifically Annex 8, which outlines the responsibilities of the State of Design and the State of Registry in maintaining aircraft airworthiness. This legislative framework ensures that CASA, as Australia’s national airworthiness authority, can effectively manage and respond to safety concerns by issuing or cancelling ADs as necessary.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) that mandate safety measures for specific types of aircraft or aeronautical products. These directives are integral to ensuring the continuing airworthiness of aircraft as per Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design responsibility for maintaining airworthiness standards. CASA, as Australia’s national airworthiness authority, has the duty to review information from the State of Design and, where necessary, issue corresponding ADs to enforce these standards on aircraft registered in Australia. An example of this regulatory process was the issuance and subsequent cancellation of AD/BEECH 56/20 for Beech 56 model aircraft, which was cancelled due to the completion of required inspections and modifications. This legislative action is undertaken by the Manager, Airframes in the Airworthiness Engineering Branch on behalf of CASA, under the authority granted by the Act. Notably, this cancellation did not necessitate public consultation or a Regulatory Impact Statement, as it effectively reduces regulatory burden.
Key Provisions
The Civil Aviation Act 1988, in particular section 98, allows the Governor-General to create regulations aimed at ensuring the safety of air navigation. This includes the ability for the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs apply to specific types of aircraft or aeronautical products. Importantly, as stated in subregulation 39.001(5), an AD is classified as a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and thus is considered a legislative instrument according to section 6 of the Legislative Instruments Act 2003.
In the context of international aviation standards, the State of Design, which is the country where the aircraft is designed, holds the primary responsibility for the continuing airworthiness of an aircraft type. This includes providing necessary information to the States of Registry to ensure the aircraft's airworthiness. The State of Registry, where the aircraft is registered, must then develop or adopt appropriate requirements to maintain this airworthiness. For instance, when a State of Design issues an AD, CASA, as Australia’s national airworthiness authority, is required to assess this information and, if necessary, issue an Australian AD to enforce the requirements of the State of Design.
The obligations imposed by these regulations on parties such as CASA and the States of Registry are significant. CASA must ensure that any AD issued by a State of Design is appropriately assessed and, if deemed necessary, an Australian AD must be issued. Similarly, the State of Registry must take proactive steps to develop or adopt requirements that ensure the continuing airworthiness of aircraft registered within its jurisdiction. This involves a continuous process of assessment, compliance, and enforcement to maintain safety standards.
In terms of penalties and consequences, while the specific Civil Aviation Act 1988 and Civil Aviation Safety Regulations 1998 do not detail penalties for non-compliance with ADs, general aviation regulations often impose stringent penalties for breaches of airworthiness directives. Non-compliance can lead to severe civil and criminal penalties, including fines and imprisonment, as well as the grounding of non-compliant aircraft. The seriousness of these penalties underscores the importance of adhering to ADs in maintaining the safety and airworthiness of aircraft.
