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 55/28, affecting Beech 55 model aircraft in 1972. 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 normal maintenance practices adequately address the requirements.
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, addresses the overarching regulation of civil aviation in Australia, with a focus on ensuring the safety of air navigation. Under this Act, the Civil Aviation Safety Regulations 1998 were established to provide detailed regulatory requirements for the operation and maintenance of aircraft. One such regulatory mechanism is the issuance of airworthiness directives (ADs) to ensure the ongoing airworthiness of aircraft. The ADs are legislative instruments that mandate safety improvements and maintenance practices. In accordance with the Convention on International Civil Aviation, the State of Design is responsible for the continuing airworthiness of an aircraft type, while the State of Registry must ensure the ongoing airworthiness of individual aircraft registered within its jurisdiction. CASA, as Australia's national airworthiness authority, issues Australian ADs to enforce the requirements set by the State of Design. In the case of AD/BEECH 55/28, CASA decided to cancel this AD for 1972 model Beech 55 aircraft, effective from 5 June 2008, due to the adequacy of normal maintenance practices in addressing the requirements previously specified by the AD.
Scope and Application
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, governs the issuance of airworthiness directives (ADs) in Australia, ensuring the safety of air navigation. Pursuant to section 98 of the Act, the Governor-General may establish regulations in the interest of air navigation safety, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products. An AD is considered a legislative instrument as per the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The State of Design holds overall responsibility for the continuing airworthiness of an aircraft type, and the State of Registry must ensure the continuing airworthiness of individual aircraft, with CASA as the national airworthiness authority responsible for assessing and issuing ADs in Australia. The issuance of ADs is aligned with Annex 8 of the Convention on International Civil Aviation, ensuring consistency across ICAO Contracting States. CASA issued AD/BEECH 55/28 affecting Beech 55 model aircraft in 1972; however, following a review, CASA has decided to cancel it, effective from 5 June 2008, as normal maintenance practices now adequately address the requirements. The cancellation of the AD aims to reduce the regulatory burden, and no public consultation or Regulatory Impact Statement was deemed necessary. The AD cancellation was made by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation (Safety) Regulations 1998 (Cth), specifically regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain kinds of aircraft or aeronautical products. These ADs, as provided in subregulation 39.001(5), are classified as disallowable instruments under section 46A of the Acts Interpretation Act 1901, and as such, are legislative instruments under section 6 of the Legislative Instruments Act 2003. This regulatory framework is designed to ensure the safety of air navigation, in accordance with section 98 of the Civil Aviation Act 1988.
Under the Civil Aviation Safety Regulations 1998, CASA must assess information provided by the State of Design regarding continuing airworthiness of an aircraft type, and if necessary, issue an Australian AD to enforce the requirements of the State of Design. The State of Registry, which in the case of Australia is CASA, is responsible for ensuring the continuing airworthiness of individual aircraft registered in Australia. This includes the obligation to develop or adopt requirements to ensure such airworthiness, as per Annex 8 to the Convention on International Civil Aviation. This Annex also stipulates that the State of Design has the overarching responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to States of Registry.
The Civil Aviation (Safety) Regulations 1998 do not require CASA to consult with the Australian public when cancelling an AD, particularly when 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. In the specific case of AD/BEECH 55/28, issued by CASA for Beech 55 model aircraft in 1972, CASA has reviewed the AD and decided to cancel it, effective from 5 June 2008. No replacement AD is required, as normal maintenance practices adequately address the requirements.
Should CASA fail to comply with the requirements of the Civil Aviation (Safety) Regulations 1998, there could be potential civil or criminal consequences, though the specific provisions of the Act do not detail the penalties for non-compliance with ADs. However, generally under Australian law, breaches of regulations can result in fines and, in more severe cases, imprisonment. The exact penalties would depend on the nature and severity of the breach.
