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.

Transport Canada has issued AD CF-1997-23R3 affecting Bell 430 model helicopters.  Canada is the State of Design for this type.  CASA has assessed this AD and has issued Australian AD/BELL 430/13, which will become effective on 5 June 2008.

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 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 provide for the regulation of civil aviation and the safety of air navigation within Australia. This Act empowers the Governor-General to make regulations that serve the interests of safety, including the issuance of airworthiness directives (ADs) as stipulated under section 98. Complementing the Act, the Civil Aviation Safety Regulations 1998, particularly regulation 39.001, authorise the Civil Aviation Safety Authority (CASA) to issue ADs concerning types of aircraft or aeronautical products. The ADs are legislative instruments, disallowable under section 46A of the Acts Interpretation Act 1901 and governed by the Legislative Instruments Act 2003. The Civil Aviation Act 1988, through its provisions and the subsequent regulations, aims to ensure the continuing airworthiness of aircraft registered in Australia, aligning with the responsibilities outlined in Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design the overall responsibility for the airworthiness of an aircraft type.

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 (ADs) for specific types of aircraft or aeronautical products to ensure the safety of air navigation. These ADs, which are considered legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003, are mandated by Australia's obligations under Annex 8 to the Convention on International Civil Aviation. This framework assigns the State of Design the responsibility for the continuing airworthiness of an aircraft type, with the State of Registry ensuring that the individual aircraft meets airworthiness standards. When an AD is issued by the State of Design, such as Transport Canada's AD CF-1997-23R3 for Bell 430 model helicopters, CASA must assess this information and, if necessary, issue a corresponding Australian AD. For instance, CASA issued Australian AD/BELL 430/13, effective from 5 June 2008, in response to the Canadian directive. Given the international nature of these directives and their basis in aviation safety, these ADs are not subject to public consultation or a Regulatory Impact Statement. Instead, they are issued by CASA's Manager, Airframes in the Airworthiness Engineering Branch, in line with the provisions of the Civil Aviation Act 1988.

Key Provisions

The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a framework for ensuring the safety of air navigation, with particular focus on the issuance and enforcement of airworthiness directives (ADs). Under section 98 of the Civil Aviation Act 1988, the Governor-General is empowered to make regulations that serve the interests of safety in air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. Furthermore, subregulation 39.001(5) specifies that an AD is a disallowable instrument, meaning it can be reviewed and potentially disallowed by Parliament. It is classified as a legislative instrument under section 6 of the Legislative Instruments Act 2003. The obligations placed on entities by these provisions are significant. The State of Design has the primary responsibility for the continuing airworthiness of an aircraft type, including providing necessary information to States of Registry. The State of Registry, in turn, must ensure that each aircraft under its jurisdiction meets airworthiness standards, often through the implementation of ADs issued by the State of Design. In Australia, CASA is the national airworthiness authority responsible for assessing ADs issued by foreign States of Design and, if necessary, issuing corresponding Australian ADs to mandate the required safety measures. This process ensures that Australian-registered aircraft meet international safety standards. Failure to comply with ADs can result in severe consequences. Under section 98(1) of the Civil Aviation Act 1988, CASA can impose penalties for non-compliance with airworthiness directives. The specific penalties depend on the nature and severity of the breach but can include substantial fines and, in severe cases, criminal charges leading to imprisonment. The Civil Aviation Safety Regulations 1998 further outline the enforcement mechanisms and potential sanctions for breaches, ensuring that airworthiness standards are rigorously enforced to maintain the highest levels of safety in air navigation.
