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 United States FAA issued AD 2003-04-01, affecting Hartzell Propellers. The United States is the State of Design for these propellers.  As a result of a request from industry, CASA has amended the equivalent Australian AD to AD/PHZL/82 Amendment 1 which will become effective on 6 July 2006.  This AD cancels and replaces the previous issue.

As this AD is issued because of Australia’s obligations under Convention on International Civil Aviation, and because it is issued in response to an AD raised by the relevant State of Design, no consultation of the Australian public has taken place on this AD.  The Office of Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.

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 was enacted to ensure the safety and efficiency of civil aviation in Australia. This legislation provides a legal framework that allows for the regulation of civil aviation activities, including the safety of air navigation. One of the significant tools under this Act is the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These directives are critical for ensuring that aircraft and aeronautical products meet the necessary safety standards. The Civil Aviation Safety Regulations 1998 further define the process for issuing ADs, which are considered legislative instruments under the Legislative Instruments Act 2003. The ADs are essential for maintaining the continuing airworthiness of aircraft, a responsibility shared between the State of Design and the State of Registry, as outlined in Annex 8 to the Convention on International Civil Aviation. The objective of this legislative framework is to harmonise Australia's aviation safety regulations with international standards, ensuring the safe and efficient operation of aircraft within Australian airspace.

Scope and Application

The Civil Aviation Safety Regulations 1998, as authorised by the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products to ensure air navigation safety. These directives apply to the entities responsible for the airworthiness of aircraft within Australia, including aircraft manufacturers, operators, and other relevant parties. The geographic scope of these regulations extends to all aircraft registered in Australia, encompassing both national and international obligations under the Convention on International Civil Aviation. Notably, ADs are legislative instruments subject to disallowance and are made in accordance with the Legislative Instruments Act 2003. While ADs do not typically require public consultation or a Regulatory Impact Statement, they are mandated by Australia's international obligations and in response to directives issued by the aircraft's State of Design. CASA issues these directives to align with the continuing airworthiness requirements established by the State of Design, ensuring compliance with international standards and safety protocols.

Key Provisions

The Civil Aviation Act 1988 (section 98) grants the Governor-General the authority to create regulations, specifically aimed at ensuring the safety of air navigation. Under the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) is empowered to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, as per regulation 39.001. These directives are legislative instruments as per subregulation 39.001(5) and section 46A of the Acts Interpretation Act 1901. Such directives are essential for maintaining the continuing airworthiness of aircraft, as stipulated under Annex 8 of the Convention on International Civil Aviation. The ADs play a crucial role in ensuring the safety of aircraft by mandating specific requirements for their operation and maintenance. The State of Design is responsible for providing necessary information to maintain the airworthiness of an aircraft type, which is then adopted by the State of Registry. CASA, as Australia's national airworthiness authority, reviews the information provided by the State of Design and issues Australian ADs when necessary. This process ensures that Australian-registered aircraft comply with international safety standards. Under the Civil Aviation Act 1988, CASA must assess and implement ADs issued by other countries when they affect aircraft registered in Australia. For example, CASA amended the Australian AD for Hartzell Propellers following the issuance of a corresponding AD by the United States Federal Aviation Administration (FAA). This amendment, effective from 6 July 2006, cancels and replaces the previous AD, ensuring that Australian-registered aircraft comply with the updated safety requirements. This action underscores the importance of international cooperation in maintaining air safety standards. Breaching the requirements set out in these ADs can lead to serious consequences. Operators who fail to comply with the mandated requirements may face enforcement actions, including fines and potential suspension or revocation of their airworthiness certificates. The Civil Aviation Safety Regulations 1998 impose obligations on aircraft operators to adhere to these directives, and non-compliance can result in significant penalties. The maximum penalties for such breaches can include substantial fines and imprisonment, highlighting the critical nature of these safety measures.
