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, the Civil Aviation Safety Authority (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.
CASA or its predecessors issued AD/CESSNA 400/14 affecting Cessna 421 model aircraft. CASA has reviewed this AD and as a result has cancelled it. The cancellation will become effective on 28 August 2008. No replacement AD is required.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, no consultation with the Australian public has taken place on this AD cancellation. 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, Systems and New Technologies 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 Commonwealth Parliament, provides the legislative framework for civil aviation in Australia, aiming to ensure the safety and efficiency of air navigation. One of the mechanisms under this Act is the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA), which are regulations made to maintain the safety of aircraft. The Civil Aviation Safety Regulations 1998 detail the process for issuing these directives, which are integral for ensuring the continuing airworthiness of aircraft as per international standards set by the International Civil Aviation Organization (ICAO). The Act empowers CASA to issue such directives, which are considered legislative instruments under the Legislative Instruments Act 2003. Recently, CASA reviewed and subsequently cancelled AD/CESSNA 400/14, which affected Cessna 421 model aircraft, in accordance with Australia’s obligations under the Convention on International Civil Aviation, rendering the need for public consultation or a Regulatory Impact Statement unnecessary. This cancellation reflects CASA's commitment to adhering to international civil aviation standards while ensuring the safety and airworthiness of aircraft in Australia.
Scope and Application
The Civil Aviation Act 1988, through the Civil Aviation Safety Regulations 1998, grants the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs serve as a critical mechanism for ensuring the continuing airworthiness of aircraft, aligning with Australia's obligations under the Convention on International Civil Aviation. The State of Design holds primary responsibility for the ongoing airworthiness of an aircraft type and must provide necessary information to the State of Registry, which is tasked with ensuring the airworthiness of individual aircraft. This legislative framework underscores the importance of international cooperation and adherence to ICAO standards. Notably, the AD/CESSNA 400/14 concerning Cessna 421 model aircraft, previously issued by CASA, has been cancelled effective 28 August 2008, reflecting the dynamic nature of airworthiness requirements and the influence of international conventions on domestic regulatory decisions. The cancellation of this AD was made in accordance with the Act, without public consultation or the need for a Regulatory Impact Statement, underscoring the streamlined process for such regulatory adjustments.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 collectively empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. According to section 98 of the Act, the Governor-General can enact regulations for the safety of air navigation, and regulation 39.001 of the Regulations grants CASA the authority to issue ADs (paragraph 39.001(5)). These ADs are considered legislative instruments under section 6 of the Legislative Instruments Act 2003 and are disallowable instruments as per section 46A of the Acts Interpretation Act 1901.
The obligations imposed by these regulations primarily concern the State of Design and the State of Registry. The State of Design, as outlined in Annex 8 of the Convention on International Civil Aviation, bears the responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to ensure that the aircraft remain airworthy. Similarly, the State of Registry must establish or adopt requirements to maintain the airworthiness of individual aircraft. This responsibility ensures that both the design and operational aspects of aircraft safety are meticulously managed.
The Civil Aviation Safety Regulations 1998, through CASA, issued AD/CESSNA 400/14 concerning Cessna 421 model aircraft. However, CASA has reviewed and subsequently cancelled this AD, effective as of 28 August 2008. The cancellation is a result of Australia’s commitments under the Convention on International Civil Aviation, and therefore, no consultation with the Australian public was necessary. Additionally, the Office of Best Practice Regulation has determined that ADs do not necessitate a Regulatory Impact Statement.
In terms of consequences for non-compliance, the Act and Regulations do not explicitly state penalties or consequences for failing to adhere to an AD. However, failure to comply with airworthiness requirements can lead to severe civil or criminal penalties under other sections of the Civil Aviation Act 1988, including fines and imprisonment. CASA retains the authority to enforce compliance through various means, including inspections, audits, and legal action if necessary.
