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.
The US FAA issued AD 90-08-12, affecting Beech 55 model aircraft, in 1990. The USA is the State of Design for this type. As a result of a request from industry, CASA has amended the equivalent Australian AD to allow the use of updated service information. The amended AD, AD/BEECH 55/62 Amendment 5, will become effective on 15 February 2007. This AD cancels and replaces the previous issue.
As this AD is issued because of Australia’s obligations under Convention on International Civil Aviation, and because it is issued in response to an AD raised by the relevant State of Design, no consultation of the Australian public has taken place on this AD. The Office of Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Airframes in the Manufacturing, Certification and New Technologies Office, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Commonwealth Parliament, establishes the legislative framework for civil aviation in Australia, aiming to ensure the safety and efficiency of air navigation within the country. This Act grants the authority to the Governor-General to make regulations that serve the interests of air navigation safety, as demonstrated in the Civil Aviation Safety Regulations 1998. These regulations empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives, which are legislative instruments designed to maintain the airworthiness of aircraft and aeronautical products. This mechanism is crucial for aligning Australian civil aviation practices with international standards, particularly under the Convention on International Civil Aviation. The directives ensure that Australia, as a State of Registry, meets its obligations in maintaining the continuing airworthiness of aircraft types registered within its jurisdiction, thereby enhancing overall aviation safety.
Scope and Application
The Civil Aviation Safety Regulations 1998, as part 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 directives are intended to ensure the safety of air navigation in Australia and are issued in accordance with Australia's obligations under the Convention on International Civil Aviation, particularly Annex 8. ADs are issued by the State of Design for an aircraft type and are required to be assessed and, if appropriate, adopted by the State of Registry, which in Australia is CASA. This legislative framework applies to all aircraft registered in Australia and the aeronautical products used within them, as well as to manufacturers, operators, and other entities involved in the aviation industry. While ADs are legislative instruments subject to disallowance under the Acts Interpretation Act 1901, and thus require adherence to the Legislative Instruments Act 2003, they are not subject to public consultation or the need for a Regulatory Impact Statement as they are directly derived from international obligations and the determinations of the State of Design. The ADs extend their application nationally, ensuring uniform safety standards across all registered aircraft within Australia.
Key Provisions
The key operative sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, particularly section 98 and regulation 39.001, empower the Governor-General to enact regulations for aviation safety, and CASA to issue airworthiness directives (ADs) for specific aircraft types or aeronautical products. These ADs are legislative instruments as per the Legislative Instruments Act 2003, ensuring they hold legal authority (sections 98, 39.001, 46A, 6). The State of Design holds primary responsibility for the continuing airworthiness of an aircraft type under Annex 8 to the Convention on International Civil Aviation, and must provide necessary information to States of Registry, including Australia, to maintain airworthiness. CASA, as Australia’s national airworthiness authority, must then assess this information and issue corresponding Australian ADs when necessary.
Entities and individuals governed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 are obligated to adhere to the ADs issued by CASA. This includes ensuring that the aircraft meet the airworthiness standards stipulated in these directives. The State of Registry, which in this context is Australia, must develop or adopt requirements to ensure the continuing airworthiness of aircraft, ensuring compliance with both domestic and international standards. These obligations extend to manufacturers, operators, and maintenance providers who must implement the specified maintenance, repair, and operational procedures outlined in the ADs.
Breach of the requirements outlined in an airworthiness directive can lead to various civil and criminal consequences. Failure to comply with ADs can result in the grounding of an aircraft, fines, and other penalties as stipulated by the Civil Aviation Act 1988 and other related legislation. The maximum penalties for non-compliance can include substantial fines and imprisonment, reflecting the serious nature of aviation safety regulations. These consequences are intended to ensure that all parties involved in aviation operations prioritise safety and adhere to the prescribed standards to prevent accidents and ensure the safe operation of aircraft.
