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 Civil Aviation Safety Authority or its predecessors issued AD/BELL 206/25 affecting Bell 206A model aircraft.  CASA has assessed this AD and as a result has cancelled it.  The cancellation will become effective on 23 October 2008.  No replacement AD is required, as the unsafe condition no longer exists.

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, Systems and New Technologies in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.

Overview

The Civil Aviation Act 1988 was enacted to establish a legislative framework for the regulation of civil aviation in Australia, ensuring the safety and efficiency of air navigation. It empowers the Governor-General to create regulations under section 98 to safeguard air navigation. Complementing this Act, the Civil Aviation Safety Regulations 1998 provide the Civil Aviation Safety Authority (CASA) with the authority to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, as outlined in regulation 39.001. These ADs are considered legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The Act’s purpose is to maintain and enhance the safety standards of civil aviation, in alignment with Australia's international obligations under the Convention on International Civil Aviation. CASA, as the national airworthiness authority, ensures that Australian aircraft meet the necessary safety standards by issuing or cancelling ADs as appropriate.

Scope and Application

The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specified types of aircraft or aeronautical products to ensure the safety of air navigation. These regulations apply to the State of Design and the State of Registry of an aircraft, with CASA assessing and, if necessary, issuing ADs to mandate the requirements of the State of Design. For example, CASA issued and subsequently cancelled AD/BELL 206/25 affecting Bell 206A model aircraft, following an assessment that the unsafe condition it addressed no longer existed. The authority to issue these directives is derived from Annex 8 to the Convention on International Civil Aviation, which outlines the responsibilities of the States of Design and Registry in ensuring the continuing airworthiness of aircraft. This legislative framework underscores the international nature of aviation safety and CASA's role as Australia’s national airworthiness authority.

Key Provisions

The Civil Aviation Safety Regulations 1998, under regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These directives are designed to ensure that aircraft and products meet the necessary safety standards. A key aspect of this regulation is the specification in subregulation 39.001(5) that an AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and therefore a legislative instrument as per section 6 of the Legislative Instruments Act 2003. These directives are pivotal for maintaining the continuing airworthiness of aircraft, a responsibility that rests with the State of Design under Annex 8 to the Convention on International Civil Aviation. The obligations imposed by the Civil Aviation Safety Regulations 1998 on CASA and other relevant authorities are significant. CASA must diligently assess any airworthiness directives issued by the State of Design, particularly when these relate to aircraft registered in Australia. If an AD is deemed necessary, CASA is required to issue a corresponding Australian AD to enforce the requirements of the original directive. This ensures that all aircraft operating within Australia adhere to the highest safety standards. The State of Registry, which in Australia is CASA, must also develop or adopt requirements to ensure the continuing airworthiness of aircraft. This involves a thorough assessment process to determine whether an AD is necessary and, if so, to implement it effectively. Failure to comply with airworthiness directives can result in serious consequences. Under the Civil Aviation Act 1988, there are both civil and criminal penalties for non-compliance. Civil penalties can include fines and other monetary penalties, while criminal penalties can include imprisonment, reflecting the gravity of the safety risks associated with non-compliance. The maximum penalties are not specified in the provided text, but they are intended to deter violations and ensure that all stakeholders take their obligations seriously. The legislative framework thus creates a robust system for maintaining the safety of air navigation through the enforcement of airworthiness directives.
