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 33/11, affecting Beech 18 model aircraft in 1971. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 20 December 2007. No replacement AD is required, as the original unsafe condition is now covered by AD/GENERAL/74.
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 Commonwealth Parliament, is the primary legislative framework governing civil aviation in Australia. This Act, along with the Civil Aviation Safety Regulations 1998, was introduced to ensure the safety of air navigation and to regulate the operation of aircraft within Australia. One of the key tools under this regulatory regime is the issuance of airworthiness directives (ADs), which are legislative instruments used to mandate safety standards and ensure the continuing airworthiness of aircraft. The Civil Aviation (Safety) Regulations 1998 empower the Civil Aviation Safety Authority (CASA) to issue these directives, which are aligned with international standards set by the International Civil Aviation Organization (ICAO). CASA's role as the national airworthiness authority involves assessing information from the State of Design and, if necessary, issuing corresponding Australian ADs. Recently, CASA has decided to cancel AD/BEECH 33/11, which affected Beech 18 model aircraft in 1971, due to its redundancy as the unsafe condition it addressed is now covered by another AD. This decision was made in accordance with the legislative provisions and did not require public consultation, as it reduces the regulatory burden.
Scope and Application
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific kinds of aircraft or aeronautical products. These directives are intended to ensure the safety of air navigation and are applicable to the continuing airworthiness of aircraft registered in Australia. The issuing of ADs is in line with international standards, particularly Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design, where the aircraft type is designed, must provide necessary information to the State of Registry to ensure continuing airworthiness. CASA, acting as Australia's national airworthiness authority, is responsible for assessing this information and issuing Australian ADs as required. ADs are legislative instruments, and their issuance must comply with the legislative processes outlined in the Legislative Instruments Act 2003. Notably, the cancellation of an AD, such as AD/BEECH 33/11 concerning Beech 18 model aircraft, is a process that may occur if the unsafe condition addressed by the AD is no longer applicable, as determined by CASA. In this specific case, the cancellation of the AD does not necessitate public consultation or a Regulatory Impact Statement, reflecting a reduction in regulatory burden.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legislative framework for the regulation of airworthiness in Australia. Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations for the safety of air navigation, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These ADs are legislative instruments that can be disallowed under section 46A of the Acts Interpretation Act 1901 and are subject to the provisions of the Legislative Instruments Act 2003.
Under the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, the State of Design, which is the State responsible for the design of the aircraft, has the overarching responsibility for the continuing airworthiness of the aircraft type. This State must provide any necessary information to the States of Registry, which are responsible for the individual aircraft registered within their jurisdiction. Annex 8 to the Convention on International Civil Aviation further supports this arrangement, requiring States of Design to issue ADs and equivalents to ensure airworthiness, and mandating States of Registry to develop or adopt requirements to maintain airworthiness. In Australia, CASA, as the national airworthiness authority, must assess information from the State of Design and, if necessary, issue Australian ADs to enforce the required measures.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 on parties and entities are primarily focused on ensuring the continuing airworthiness of aircraft. CASA must review ADs issued by the State of Design and determine if they need to be enforced in Australia through the issuance of Australian ADs. States of Registry, including CASA in Australia, must develop or adopt requirements to ensure the airworthiness of individual aircraft within their jurisdiction. Aircraft operators and owners must comply with all ADs issued under the regulations, ensuring that any required modifications or inspections are performed in accordance with the stipulated timeframes.
The Civil Aviation Safety Regulations 1998 do not explicitly outline specific offences, penalties, or civil/criminal consequences for breach of ADs. However, failure to comply with an AD may result in significant legal and operational consequences for aircraft operators and owners. CASA has the authority to take enforcement action, including grounding non-compliant aircraft, imposing fines, and taking legal action against non-compliant entities. In severe cases, breaches may lead to criminal charges under other relevant aviation legislation, such as the Civil Aviation Act 1988, with penalties including substantial fines and imprisonment. Additionally, non-compliance with ADs can result in the suspension or revocation of an aircraft's certificate of airworthiness, effectively grounding the aircraft until the necessary compliance measures are taken.
