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 US FAA has issued AD 2007-06-09 affecting Boeing B737 model aircraft.  The USA is the State of Design for this type.  CASA has assessed this AD and has issued Australian AD/B737/277 Amdt 1, which will become effective on 7 June 2007.  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, Airframes 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 establish a framework for the regulation of civil aviation in Australia, aiming to ensure the safety and efficiency of air navigation. This Act empowers the Governor-General to make regulations for the purposes of the Act, particularly in the interests of air navigation safety. One of the significant regulatory mechanisms under this Act is the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) as per regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs are legislative instruments under section 46A of the Acts Interpretation Act 1901 and are essential for maintaining the continuing airworthiness of aircraft types as per Annex 8 of the Convention on International Civil Aviation. The responsibility of the State of Registry to ensure the airworthiness of individual aircraft is complemented by the role of the State of Design in providing necessary information through ADs. CASA, acting as Australia's national airworthiness authority, must issue corresponding ADs in response to directives from the State of Design, such as the recent AD issued for Boeing B737 model aircraft following the US Federal Aviation Administration's directive. This AD, issued under the authority of CASA, reflects Australia's commitment to international civil aviation standards and obligations.

Scope and Application

The Civil Aviation Safety Regulations 1998, specifically under regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These directives are legislative instruments as defined under section 6 of the Legislative Instruments Act 2003 and are aimed at ensuring the safety of air navigation in accordance with the Civil Aviation Act 1988. ADs are issued in response to obligations under the Convention on International Civil Aviation, particularly when a State of Design issues safety measures for a particular aircraft type registered in Australia. For instance, CASA has issued Australian AD/B737/277 Amdt 1 in response to the US Federal Aviation Administration's AD 2007-06-09 for Boeing B737 model aircraft, as the USA is the State of Design. The ADs apply to the continuing airworthiness of the specified aircraft types and are mandated by the relevant State of Registry, which in this case is CASA for Australian-registered aircraft. The process does not involve public consultation or a Regulatory Impact Statement as determined by the Office of Regulatory Review. The ADs are issued under the authority of the Act, specifically under subsection 84A(2), by the Manager, Airframes within CASA's Manufacturing, Certification and New Technologies Office.

Key Provisions

The Civil Aviation Act 1988, specifically section 98, provides the framework for the Governor-General to create regulations that ensure the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are critical tools in maintaining the safety and airworthiness of aircraft, and they are legally binding instruments under section 6 of the Legislative Instruments Act 2003. The ADs serve to ensure that aircraft continue to meet the safety standards necessary for operation, and they are considered legislative instruments under the Acts Interpretation Act 1901. The obligations imposed by these regulations are significant for both the State of Design and the State of Registry. The State of Design, which is responsible for the overall airworthiness of an aircraft type, must provide necessary information to ensure that the aircraft remain airworthy. This includes issuing ADs when safety issues are identified. The State of Registry, on the other hand, must develop or adopt requirements to ensure the continuing airworthiness of aircraft registered within its jurisdiction. When a State of Design issues an AD, the State of Registry, represented by CASA in Australia, must assess this information and issue corresponding ADs as needed. This process ensures that all aircraft within the registry meet the required safety standards. Failing to comply with an airworthiness directive can have serious consequences. The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 do not explicitly detail specific penalties for non-compliance with ADs, but the overarching legal framework includes potential civil and criminal penalties for breaches of aviation safety regulations. Non-compliance with ADs can lead to severe outcomes, including fines, imprisonment, or both, as stipulated in other sections of the Civil Aviation Act 1988. The severity of the penalties reflects the critical importance of adhering to airworthiness directives to maintain the safety of air navigation. The issuance of the AD for the Boeing B737 model aircraft, specifically AD 2007-06-09 from the US Federal Aviation Administration (FAA), highlights the practical application of these provisions. CASA, as Australia’s national airworthiness authority, has assessed the US AD and issued Australian AD/B737/277 Amdt 1, effective from 7 June 2007. This Australian AD replaces the previous directive and ensures that Australian-registered Boeing B737 aircraft meet the updated safety requirements. Given that this AD is a response to international obligations under the Convention on International Civil Aviation, and because it is issued in direct response to an AD from the State of Design, no public consultation was required. Additionally, the Office of Regulatory Review has determined that such ADs do not necessitate a Regulatory Impact Statement. The AD was made by the Manager, Airframes in the Manufacturing, Certification and New Technologies Office, on behalf of CASA, in accordance with subsection 84A(2) of the Act.
