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, the Civil Aviation Safety Authority (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.
CASA or its predecessors issued AD/PA-30/12 affecting Piper PA-30 aircraft. CASA has reviewed this AD and as a result has cancelled it. The cancellation will become effective on 18 December 2008. No replacement AD is required.
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 Manager, Airframes and Structures in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Australian Parliament, establishes the framework for the regulation of civil aviation in Australia, aiming to ensure safety and efficiency in air navigation. Under this Act, the Governor-General has the authority to issue regulations in the interest of air navigation safety, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) as per regulation 39.001 of the Civil Aviation Safety Regulations 1998. The ADs, being legislative instruments, are subject to disallowance and are essential for maintaining the continuing airworthiness of aircraft as per international standards set by the Convention on International Civil Aviation. The Civil Aviation Act 1988 addresses the need for a structured approach to aviation safety regulation, ensuring compliance with both national and international standards.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the authority of the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives for specific types of aircraft or aeronautical products, thereby ensuring the safety of air navigation. These airworthiness directives are legislative instruments as defined by the Legislative Instruments Act 2003. In accordance with the Convention on International Civil Aviation, the State of Design holds the primary responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to the State of Registry to ensure ongoing airworthiness. The State of Registry, in turn, is responsible for the continuing airworthiness of individual aircraft, developing or adopting appropriate requirements. As per the Convention, CASA has issued and subsequently cancelled AD/PA-30/12 for Piper PA-30 aircraft, with the cancellation effective from 18 December 2008, and no replacement directive is required. The cancellation is a result of Australia's obligations under the Convention, thus no public consultation or Regulatory Impact Statement was necessary. The directive was made by the Manager, Airframes and Structures in the Airworthiness Engineering Group on behalf of CASA, under the authority of the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation Act 1988, in particular section 98, empowers the Governor-General to enact regulations aimed at ensuring the safety of air navigation. This legislative authority is exercised through the Civil Aviation Safety Regulations 1998, which includes regulation 39.001, allowing the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. Such ADs serve as a formal mechanism to ensure that aircraft and related products maintain their airworthiness, adhering to international standards set forth in Annex 8 to the Convention on International Civil Aviation.
Under these regulations, the State of Design holds the primary responsibility for the continuing airworthiness of an aircraft type, including the obligation to provide necessary information to the State of Registry. The State of Registry, in turn, is mandated to develop or adopt requirements that ensure the ongoing airworthiness of the aircraft within its jurisdiction. This division of responsibilities ensures that all relevant parties contribute to the overarching goal of maintaining air safety.
The Civil Aviation Safety Regulations 1998 further clarify that ADs are legislative instruments, as per section 46A of the Acts Interpretation Act 1901 and section 6 of the Legislative Instruments Act 2003. This legal status underscores the importance of these directives in maintaining safety standards. For instance, CASA has issued and subsequently cancelled AD/PA-30/12, which affected Piper PA-30 aircraft, due to Australia's obligations under the Convention on International Civil Aviation. The cancellation took effect on 18 December 2008, and no replacement AD was deemed necessary.
The process for issuing and cancelling ADs is stringent and closely tied to international obligations, which means that public consultation is often not required. The Office of Best Practice Regulation has determined that ADs do not necessitate a Regulatory Impact Statement, reflecting their technical and safety-focused nature. These directives are issued by CASA, specifically by the Manager, Airframes and Structures in the Airworthiness Engineering Group, in accordance with subsection 84A(2) of the Act.
In terms of compliance, any failure to adhere to an airworthiness directive can result in significant legal consequences. The Act does not explicitly detail the penalties for non-compliance, but given the critical nature of airworthiness directives, violations could potentially lead to severe civil or criminal penalties, including fines and imprisonment, depending on the severity and impact of the non-compliance on aviation safety.
