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 55/3, affecting Piper Beech 55 model aircraft, in 1962. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 3 July 2008. No replacement AD is required, as normal maintenance practices now address the unsafe condition
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 regulate civil aviation in Australia, focusing on safety and efficiency. One of the Act's key provisions allows the Governor-General to make regulations necessary for the safety of air navigation, with the Civil Aviation Safety Regulations 1998 detailing specific requirements. These regulations include the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA), which serve as a primary means of ensuring the continuing airworthiness of aircraft. ADs are legislative instruments that align with international standards set by the Convention on International Civil Aviation, particularly Annex 8, which outlines the responsibilities of States of Design and Registry in maintaining aircraft safety. The Civil Aviation Safety Regulations mandate that CASA, as Australia's national airworthiness authority, must assess and potentially issue Australian ADs when necessary, ensuring compliance with international safety standards and reducing regulatory burdens where appropriate.
Scope and Application
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, provides the framework for the issuance of airworthiness directives (ADs) which are instrumental in ensuring the ongoing safety of aircraft and aeronautical products in Australia. Pursuant to section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to enact regulations, including ADs, for the safety of air navigation, with the Civil Aviation Safety Authority (CASA) being the body responsible for their issuance under regulation 39.001. These ADs apply to specific types of aircraft or aeronautical products and are considered disallowable instruments as per section 46A of the Acts Interpretation Act 1901, thereby classifying them as legislative instruments under section 6 of the Legislative Instruments Act 2003. ADs are issued by CASA, the national airworthiness authority, to ensure compliance with international standards set out in Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design provides necessary information to ensure the continuing airworthiness of an aircraft type. The State of Registry, in this case CASA, must then develop or adopt requirements to ensure the continuing airworthiness of aircraft registered in Australia, which may include issuing Australian ADs in response to those issued by the State of Design. The scope of these regulations is national, covering all aircraft registered in Australia and affecting the responsibilities of aircraft manufacturers, operators, and other entities involved in the maintenance and operation of these aircraft.
Key Provisions
The Civil Aviation Act 1988 provides the overarching legislative framework for civil aviation in Australia, with the Civil Aviation Safety Regulations 1998 offering detailed guidance on specific operational and safety standards. Section 98 of the Act allows the Governor-General to make regulations to ensure the safety of air navigation, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These ADs are legislative instruments, as stipulated by subregulation 39.001(5) and section 46A of the Acts Interpretation Act 1901, and they are further regulated under the Legislative Instruments Act 2003.
Under these provisions, the State of Design, which is the country where the aircraft is designed, holds the primary responsibility for ensuring the continuing airworthiness of an aircraft type. This includes providing necessary information to the State of Registry, which is the country where the aircraft is registered, to maintain airworthiness. CASA, as Australia's national airworthiness authority, is tasked with assessing information from the State of Design and issuing Australian ADs if necessary. This ensures that Australian-registered aircraft meet the required safety standards.
In terms of obligations, CASA must review ADs issued by the State of Design and determine whether they need to be implemented in Australia. If CASA deems it necessary, they issue an Australian AD that mandates the requirements specified by the State of Design. Additionally, CASA must consult with relevant stakeholders and ensure that any ADs issued are in line with international standards set by the Convention on International Civil Aviation, specifically Annex 8.
Should any party fail to comply with the requirements set out in an AD, there may be significant consequences. The Act does not explicitly outline specific offences or penalties for non-compliance with ADs, but general provisions within the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 may apply. Non-compliance could lead to enforcement actions, fines, or other regulatory sanctions. Additionally, failure to adhere to ADs could result in severe safety risks, potentially leading to aircraft being grounded or prohibited from operating until compliance is achieved.
