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 raised AD/BAL/3 Amendment 4 to correct an unsafe situation on Hot Air Balloon aircraft. This Airworthiness Directive mandates maintenance, overhaul and retirement lives for LP Gas Cylinders. As a result of a request from industry, CASA has amended the Australian AD to reference the current amendments of the relevant Australian Standards. The amended AD, AD/BAL/3 Amendment 5, will become effective on 9 July 2010. This AD cancels and replaces the previous issue.
CASA has not consulted with the Australian industry and public because the change is an administrative amendment to align with current Australian Standards and State requirements.
The Office of Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Continuing Airworthiness, Airworthiness and Engineering Branch, on behalf of CASA, in accordance with subsection 94 (1) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide a legislative framework for the regulation of civil aviation in Australia, with an emphasis on ensuring the safety and efficiency of air navigation. Under the Act, the Governor-General has the authority to make regulations for the purposes of the Act and in the interests of the safety of air navigation. The Civil Aviation Safety Regulations 1998, made under the authority of the Act, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products to maintain the continuing airworthiness of aircraft. These ADs are legislative instruments subject to disallowance. The Civil Aviation Act 1988 aims to facilitate the safe, efficient and orderly development of civil aviation in Australia by providing a comprehensive regulatory framework overseen by CASA.
Scope and Application
The Civil Aviation (Airworthiness) Regulations 1998, as an extension of the Civil Aviation Act 1988, pertain to the continuing airworthiness of aircraft, including the issuance of airworthiness directives (ADs). The scope of the regulations applies to aircraft registered in Australia and the operators of these aircraft, ensuring compliance with safety standards mandated by the Civil Aviation Safety Authority (CASA). The regulations are intended to address potential safety issues identified in specific types of aircraft or aeronautical products. The authority to issue ADs is vested in CASA, which must align with the continuing airworthiness information provided by the State of Design, typically the manufacturer, and ensure that Australian requirements are met. This legislative framework extends nationally and applies to all aircraft registered under Australian jurisdiction, irrespective of the location of the aircraft or the nationality of the operator. The ADs themselves are legislative instruments that are disallowable under the Acts Interpretation Act 1901, subject to scrutiny and review as per the Legislative Instruments Act 2003. The ADs serve to mandate corrective actions and maintenance schedules to ensure safety and compliance with international standards as set out in Annex 8 to the Convention on International Civil Aviation. In the specific case of AD/BAL/3 Amendment 4, which was updated to AD/BAL/3 Amendment 5, the amendments address safety concerns related to LP Gas Cylinders in Hot Air Balloon aircraft and were made to align with current Australian Standards, without the need for consultation or a Regulatory Impact Statement due to the administrative nature of the change.
Key Provisions
The Civil Aviation Act 1988, through 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 instrumental in ensuring the safety and airworthiness of aircraft and are considered legislative instruments as they are disallowable under section 46A of the Acts Interpretation Act 1901 and regulated under the Legislative Instruments Act 2003. Section 98 of the Civil Aviation Act 1988 underpins this regulatory power, allowing the Governor-General to create such regulations for the safety of air navigation.
The obligations under this legislation require CASA to monitor and respond to airworthiness issues identified by the State of Design, which has overall responsibility for the continuing airworthiness of aircraft types as outlined in Annex 8 to the Convention on International Civil Aviation. Specifically, the State of Registry, which is the country where the aircraft is registered, must ensure that the aircraft remains airworthy by adopting or developing requirements to that effect. When CASA issues an AD, it mandates compliance with the identified safety measures, which must then be adhered to by the State of Registry and the aircraft operators.
Non-compliance with ADs can result in severe consequences. While the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 do not specify particular offences or penalties within the text of the ADs themselves, general aviation regulations provide for potential penalties, including fines and imprisonment, for violations of safety regulations. The specific consequences would depend on the nature of the breach and the discretion of the courts in applying the broader regulatory framework.
In the case of the AD/BAL/3 Amendment 4, CASA issued an amendment to address an unsafe situation concerning LP Gas Cylinders on hot air balloons. This amendment was made to mandate maintenance, overhaul, and retirement lives for these cylinders. The subsequent amendment, AD/BAL/3 Amendment 5, aligns with current Australian Standards and State requirements. Although CASA did not consult with industry and the public due to the administrative nature of the changes, the authority to issue such directives remains firmly within their purview. The Office of Regulatory Review has concluded that these ADs do not necessitate a Regulatory Impact Statement, underscoring their regulatory rather than legislative nature.
