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/PHS/8, affecting Hamilton Standard propellers. CASA has reviewed this AD and determined that the requirements of this AD have been adequately addressed. It has been determined that the unsafe condition no longer exists. CASA has determined that AD/PHS/8 will be cancelled with an effective date of 23 November 2006.
The AD has been made by the Manager, New Technologies and Systems, 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 Australian Parliament, aims to ensure the safety of civil aviation in Australia, including the regulation of airworthiness. Under this Act, the Civil Aviation Safety Regulations 1998 were made to further detail the requirements and procedures for maintaining airworthiness. Specifically, regulation 39.001 of these Regulations empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs), which are legislative instruments that mandate actions to ensure the continuing airworthiness of aircraft. This regulatory framework is designed to align with international standards, particularly those set by the International Civil Aviation Organization (ICAO), ensuring that Australia’s approach to aircraft safety is consistent with global practices. CASA's issuance and subsequent cancellation of AD/PHS/8 demonstrates the practical application of these regulations in addressing specific safety concerns related to aircraft components, such as Hamilton Standard propellers.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the authority of the Civil Aviation Act 1988, enable the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These directives serve to ensure the continuing airworthiness of aircraft registered in Australia, in line with international standards set by the Convention on International Civil Aviation. As a legislative instrument, an AD is subject to disallowance under the Acts Interpretation Act 1901 and is regulated under the Legislative Instruments Act 2003. The AD applies to aircraft types within the Australian Register and is issued in response to directives from the State of Design, with CASA assessing and, if necessary, issuing Australian ADs to enforce the required safety measures. Subordinate instruments may further extend or restrict the application of these regulations, ensuring that the standards and requirements remain consistent with both national and international safety protocols.
Key Provisions
The Civil Aviation Safety Regulations 1998, under regulation 39.001, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives (section 39.001(5)) are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and thus they qualify as legislative instruments as per section 6 of the Legislative Instruments Act 2003. The authority to issue ADs stems from section 98 of the Civil Aviation Act 1988, enabling the Governor-General to make regulations for air navigation safety.
The obligations of the State of Design, as per Annex 8 of the Convention on International Civil Aviation, include maintaining the continuing airworthiness of aircraft types and providing necessary information to the States of Registry to ensure safety. The State of Registry, in turn, is responsible for ensuring the continuing airworthiness of individual aircraft. When a State of Design issues an AD, CASA, as Australia’s national airworthiness authority, must assess this information and, if necessary, issue an Australian AD to enforce the requirements. This process ensures that the safety standards set by the State of Design are implemented in Australia.
In the case of AD/PHS/8, issued by CASA and affecting Hamilton Standard propellers, CASA has reviewed the directive and concluded that the unsafe conditions it addressed have been resolved. As a result, CASA has decided to cancel AD/PHS/8, effective from 23 November 2006. This decision was made by the Manager, New Technologies and Systems, in the Manufacturing, Certification and New Technologies Office, on behalf of CASA, in accordance with subsection 84A(2) of the Civil Aviation Act 1988.
Failure to comply with an AD can result in serious consequences. Non-compliance may lead to civil or criminal penalties, depending on the severity of the breach. The Civil Aviation Act 1988 and associated regulations impose strict obligations on parties and entities governed by these laws. Penalties for non-compliance can include substantial fines and, in more severe cases, imprisonment. The exact penalties depend on the specific breach and can vary widely, but they are designed to ensure strict adherence to safety regulations and to deter non-compliance.
