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/HU 269/88 affecting Schweizer (Hughes) 269 series Helicopters.  CASA has assessed this AD and as a result has cancelled Australian AD/HU 269/88.  The cancellation will become effective on 7 May 2009.  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, Airframe and Structures, 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 ensure the safety and efficiency of civil aviation in Australia. It empowers the Governor-General to create regulations under section 98, which is further operationalised through the Civil Aviation Safety Regulations 1998. The Civil Aviation Safety Regulations 1998, particularly regulation 39.001, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specified aircraft or aeronautical products, which are critical for maintaining the continuing airworthiness of aircraft. These directives are legislative instruments, as per the Legislative Instruments Act 2003. The policy objective of these regulations is to align with international standards, specifically those outlined in Annex 8 of the Convention on International Civil Aviation, which mandates the State of Design to provide necessary information for the continuing airworthiness of aircraft types. CASA, acting as Australia’s national airworthiness authority, must then issue corresponding Australian ADs if deemed necessary, ensuring compliance with both national and international safety standards.

Scope and Application

The Civil Aviation Act 1988, as amended and supplemented by the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) to ensure the safety of aircraft and aeronautical products. These regulations apply to all aircraft and aeronautical products that are subject to the Act, including but not limited to, aircraft manufacturers, operators, and maintenance providers. The geographic reach of these regulations is national, as CASA acts as Australia's central authority for airworthiness. Under the Act, CASA must issue ADs if required by Australia's obligations under international conventions, specifically Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design provides necessary information for the continuing airworthiness of an aircraft type. Additionally, the State of Registry, in this case, CASA, must ensure the continuing airworthiness of aircraft on the Australian Register. ADs are legislative instruments and subject to disallowance under the Acts Interpretation Act 1901. This particular AD, AD/HU 269/88 affecting Schweizer (Hughes) 269 series Helicopters, was issued and subsequently cancelled due to the resolution of the unsafe condition, with no replacement AD required. The cancellation process did not involve public consultation as it was aligned with Australia's international obligations.

Key Provisions

The Civil Aviation Act 1988, under section 98, allows the Governor-General to create regulations that serve the interests of air navigation safety. In line with this provision, the Civil Aviation Safety Regulations 1998, specifically regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specified types of aircraft or aeronautical products. These ADs serve as enforceable instructions to ensure the continuing airworthiness of aircraft, and they are regarded as legislative instruments under section 46A of the Acts Interpretation Act 1901 and section 6 of the Legislative Instruments Act 2003. The obligations imposed by the Civil Aviation Safety Regulations 1998 include the State of Design's responsibility to provide necessary information to ensure the continuing airworthiness of an aircraft type, as outlined in Annex 8 to the Convention on International Civil Aviation. The State of Registry, on the other hand, must develop or adopt requirements to ensure the airworthiness of individual aircraft registered within its territory. When a State of Design issues an AD, CASA must assess this information and, if deemed appropriate, issue an Australian AD to enforce the requirements of the State of Design. In the case of Australian AD/HU 269/88, which affected Schweizer (Hughes) 269 series helicopters, CASA assessed the AD and subsequently cancelled it, effective from 7 May 2009, because the unsafe condition it addressed no longer existed. No replacement AD was necessary, and no consultation with the Australian public was conducted since the cancellation was due to Australia's obligations under the Convention on International Civil Aviation. Additionally, the Office of Best Practice Regulation determined that ADs do not require a Regulatory Impact Statement. The AD was issued by the Manager, Airframe and Structures, in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A(2) of the Act. Failure to comply with ADs can result in serious consequences. Under the Civil Aviation Act 1988, non-compliance can lead to civil penalties, including fines, and criminal penalties, including imprisonment. The severity of the penalties depends on the nature and extent of the non-compliance, as well as any resulting harm or risk to aviation safety. CASA has the authority to enforce compliance through inspections, audits, and other regulatory actions, ensuring that aircraft and aeronautical products meet the required safety standards.
