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 Civil Aviation Safety Authority or its predecessors issued AD/CESSNA 210/37 affecting Cessna 210 aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/CESSNA 210/37. The cancellation will become effective on 10 April 2008. No replacement AD is required, as the unsafe condition no longer exists.
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 Acting 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 Australian Parliament, aims to ensure the safety and efficiency of civil aviation. This Act provides the framework for the regulation of civil aviation safety in Australia, including the authority for the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. These directives are legislative instruments designed to mandate specific safety measures for aircraft and aeronautical products to maintain airworthiness. The cancellation of AD/CESSNA 210/37 affecting Cessna 210 aircraft, announced by CASA, reflects Australia’s adherence to the Convention on International Civil Aviation, particularly Annex 8, which mandates that States of Design must provide necessary information to ensure the continuing airworthiness of aircraft types. CASA, as Australia’s national airworthiness authority, is responsible for assessing this information and issuing appropriate directives. The cancellation of this AD on 10 April 2008, with no replacement required due to the resolution of the unsafe condition, underscores CASA’s commitment to ensuring the safety of air navigation in accordance with international obligations.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, applies to entities and individuals involved in the operation, maintenance, and registration of aircraft within Australia. The Act provides the authority for the issuance of airworthiness directives (ADs) to ensure the safety of air navigation. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for kinds of aircraft or aeronautical products. These ADs are legislative instruments, as outlined under section 6 of the Legislative Instruments Act 2003, and serve as a means of continuing airworthiness information, mandated under Annex 8 to the Convention on International Civil Aviation. The State of Design of an aircraft type has the overarching responsibility for ensuring continuing airworthiness, while the State of Registry, in this case CASA, must implement these directives to maintain the safety standards of aircraft registered in Australia. This legislation applies nationally, covering all aircraft registered within Australia and ensuring compliance with international safety standards.
Key Provisions
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, establishes a framework for ensuring the safety of air navigation. Section 98 of the Act empowers the Governor-General to make regulations to safeguard air navigation, while regulation 39.001 of the Regulations allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning types of aircraft or aeronautical products. These ADs are legislative instruments that serve as a crucial form of continuing airworthiness information under Annex 8 of the Convention on International Civil Aviation. The State of Design holds the primary responsibility for ensuring an aircraft type's airworthiness, and it must provide necessary information to the State of Registry to maintain the safety of aircraft registered in their jurisdiction.
The obligations imposed by these regulations include the requirement for the State of Design to issue ADs for aircraft types, ensuring they address any unsafe conditions. The State of Registry must then assess this information and, if necessary, issue corresponding ADs to enforce the safety requirements. In Australia, CASA, as the national airworthiness authority, has the duty to evaluate ADs issued by other states and determine whether they need to be adopted or adapted to Australian conditions. This process ensures that Australian-registered aircraft meet the necessary safety standards.
Failure to comply with airworthiness directives can result in serious safety risks. Under the Civil Aviation Act 1988, breaches of airworthiness requirements can lead to civil and criminal penalties. For example, knowingly allowing an aircraft to fly while it is not airworthy is a criminal offence, carrying a maximum penalty of $330,000 or imprisonment for up to five years, or both. Similarly, the Civil Aviation Safety Regulations 1998 outline penalties for non-compliance with ADs. Specifically, the operation of an aircraft that does not comply with an AD is an offence, and the maximum penalty for this can be substantial, reflecting the serious nature of endangering public safety in the air. Therefore, adherence to ADs and the regulations is critical to maintaining the high safety standards expected in civil aviation.
