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/CESSNA 150/3, affecting Cessna 150 model aircraft in 1961.  CASA has reviewed this AD and as a result has decided to cancel it.  The cancellation will become effective on 14 February 2008.  No replacement AD is required, as the original unsafe condition has long ceased to exist.

No consultation with the Australian public has taken place on this AD cancellation, because the cancellation results in a reduction of the regulatory burden.  The Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.

 

The AD has been made by the Acting 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 in Australia, ensuring safety and efficiency in air navigation. The Act empowers the Governor-General to make regulations, including the Civil Aviation Safety Regulations 1998, which allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for aircraft and aeronautical products. The policy objective is to maintain the safety of air navigation by ensuring that aircraft are airworthy and meet continuing airworthiness requirements as outlined in Annex 8 to the Convention on International Civil Aviation. CASA's role is to issue ADs based on the continuing airworthiness information provided by the State of Design and to ensure these directives are implemented by the State of Registry. The AD/CESSNA 150/3 cancellation, issued by CASA, exemplifies the regulatory process, aiming to reduce regulatory burden and ensure safety without necessitating a Regulatory Impact Statement or public consultation.

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) that apply to specific types of aircraft or aeronautical products to ensure the safety of air navigation. These directives are legislative instruments that apply to aircraft registered in Australia, regardless of their state or territory of operation. As Australia adheres to Annex 8 of the Convention on International Civil Aviation, the State of Design of an aircraft type is responsible for its continuing airworthiness, while the State of Registry, in this case CASA, is tasked with ensuring compliance with the ADs. The scope of the ADs includes mandating requirements set by the State of Design, which must be assessed and, if necessary, adopted or modified by CASA to align with Australian regulations. The issuance of ADs is a critical mechanism for maintaining the safety standards of aircraft in Australia, and their issuance is a routine part of CASA’s regulatory activities.

Key Provisions

The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, establishes a framework for ensuring the safety of air navigation, which includes the issuance of airworthiness directives (ADs). According to section 98 of the Act, the Governor-General has the authority to make regulations in the interests of safety. Regulation 39.001 allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products. This process ensures that any identified safety issues are addressed in a timely manner. The obligations placed on the parties governed by these provisions are significant. The State of Design, typically the country where the aircraft is designed, must provide necessary information to ensure the continuing airworthiness of an aircraft type, as stipulated in Annex 8 to the Convention on International Civil Aviation. The State of Registry, which is the country where the aircraft is registered, must adopt or develop requirements to ensure that the aircraft remain airworthy. CASA, as Australia’s national airworthiness authority, is responsible for assessing the information provided by the State of Design and, if appropriate, issuing an Australian AD to mandate the necessary requirements. Failure to comply with the ADs can result in various consequences. While the specific penalties are not detailed in the provided text, it is clear that non-compliance could lead to safety risks, which are inherently serious. The regulatory framework implies that breaches of airworthiness directives could lead to legal action, potentially including civil penalties or even criminal charges if the breach results in significant harm or endangers lives. The exact penalties would depend on the specific circumstances and any additional legislation that may apply. CASA's decision to cancel the AD/CESSNA 150/3, which affected Cessna 150 model aircraft from 1961, exemplifies the regulatory process in action. This cancellation, effective from 14 February 2008, is based on the determination that the original safety concern no longer exists. The decision not to consult the Australian public or prepare a Regulatory Impact Statement stems from the conclusion that this cancellation reduces the regulatory burden. The AD was issued in accordance with subsection 84A(2) of the Act, demonstrating adherence to the legislative requirements.
