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 65/11, affecting Beech 65 model aircraft in 1968. 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, primarily focusing on safety. This Act empowers the Governor-General to issue regulations under section 98, ensuring the safety of air navigation. The Civil Aviation Safety Regulations 1998, made under the authority of this Act, further delineate the procedures for maintaining airworthiness, including the issuance of airworthiness directives (ADs) as stipulated in regulation 39.001. These ADs, considered legislative instruments under the Legislative Instruments Act 2003, serve as critical mechanisms for ensuring the continuing airworthiness of aircraft. The Civil Aviation Safety Authority (CASA), acting as Australia's national airworthiness authority, assesses and issues ADs to mandate safety requirements derived from the State of Design, aligning with international standards set forth in Annex 8 of the Convention on International Civil Aviation.
Scope and Application
The Civil Aviation Safety Regulations 1998, made under the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft and aeronautical products, ensuring adherence to safety standards. These directives apply to aircraft registered within Australia and are integral to maintaining the continuing airworthiness of such aircraft as mandated by the State of Registry. Notably, the Act applies to all persons and entities involved in the operation and maintenance of aircraft within Australia, encompassing both domestic and international flights. The ADs are issued in accordance with international standards set by Annex 8 to the Convention on International Civil Aviation, ensuring consistency and compliance across jurisdictions. The ADs are legislative instruments, subject to disallowance under the Acts Interpretation Act 1901, and are issued by CASA under the authority vested in it by the Civil Aviation Act 1988. The geographic reach of these regulations is national, as CASA is the designated authority for all airworthiness matters within Australia. Any exclusions or exemptions from these regulations are not explicitly stated in the text, though the application of ADs is typically targeted at specific types of aircraft and aeronautical products, rather than broadly across all aviation activities. The issuance and enforcement of ADs are intended to reduce regulatory burdens while ensuring that safety standards are maintained, as evidenced by the decision to cancel AD/BEECH 65/11 without necessitating a replacement, given the aircraft in question have already undergone necessary inspections and modifications.
Key Provisions
The Civil Aviation Act 1988, under section 98, empowers the Governor-General to make regulations for the safety of air navigation, and the Civil Aviation Safety Regulations 1998, under regulation 39.001, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. This means that CASA can issue binding directives that dictate the maintenance, operation, and safety standards that must be adhered to by aircraft owners and operators. These ADs are considered legislative instruments under the Legislative Instruments Act 2003. This regulatory framework ensures that aircraft operating in Australia meet the necessary safety standards and remain airworthy.
Under this Act and its regulations, CASA has the responsibility to ensure the continuing airworthiness of aircraft registered in Australia. When the State of Design issues an AD for a type of aircraft on the Australian Register, CASA must review this information and, if necessary, issue a corresponding Australian AD to enforce the design state's requirements. This ensures that all aircraft operating in Australia comply with the safety standards set by the State of Design. The State of Registry also has the obligation to develop or adopt requirements to ensure the continuing airworthiness of aircraft under their jurisdiction. These obligations ensure that both the State of Design and the State of Registry play crucial roles in maintaining the safety and airworthiness of aircraft.
Failure to comply with airworthiness directives can result in significant legal consequences. Section 98 of the Civil Aviation Act 1988 and regulation 39.001 of the Civil Aviation Safety Regulations 1998 provide the legal basis for CASA to enforce compliance with ADs. Non-compliance with these directives can lead to serious safety risks, and CASA can take enforcement actions against aircraft operators and owners who fail to adhere to the mandated requirements. The consequences can include fines, suspension or revocation of aircraft certificates, and other regulatory penalties, which underscore the importance of adhering to the safety standards set forth by CASA.
The cancellation of AD/BEECH 65/11, which affected Beech 65 model aircraft from 1968, demonstrates CASA's commitment to reviewing and updating its directives to ensure they remain relevant and necessary. The decision to cancel this AD was made after a thorough review, and it was determined that no replacement AD was required as all affected aircraft had already been inspected and modified as necessary. This action highlights CASA's ongoing efforts to manage the regulatory burden and ensure that directives are proportionate and based on current safety needs. The process of cancelling this AD did not require public consultation, as it resulted in a reduction of the regulatory burden, and the Office of Best Practice Regulation determined that ADs do not require a Regulatory Impact Statement.
