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/BEECH 95/10 affecting Beechcraft 95 model aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/BEECH 95/10. The cancellation will become effective on 31 July 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, Airframe and Structures, in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Parliament of Australia, was introduced to regulate civil aviation and ensure the safety of air navigation. This Act provides the legal framework for the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998, aiming to maintain the safety standards of aircraft and aeronautical products. An AD is a legislative instrument that serves as a critical form of continuing airworthiness information, mandated by the Convention on International Civil Aviation. CASA, acting as Australia’s national airworthiness authority, is responsible for assessing international ADs and issuing corresponding directives for aircraft registered in Australia, thereby ensuring compliance with international safety standards and the ongoing airworthiness of aircraft. The legislative process for ADs is governed by the Legislative Instruments Act 2003, and specific ADs may be cancelled if the associated safety concerns are resolved, as demonstrated by the cancellation of AD/BEECH 95/10 for Beechcraft 95 model aircraft, which was cancelled by CASA without public consultation due to the resolution of the unsafe condition.
Scope and Application
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products to ensure the safety of air navigation. These ADs are legislative instruments under section 6 of the Legislative Instruments Act 2003 and are aligned with Annex 8 of the Convention on International Civil Aviation. The State of Design holds the primary responsibility for the continuing airworthiness of an aircraft type, providing necessary information to States of Registry, which then develop or adopt requirements for ensuring the airworthiness of aircraft within their jurisdiction. In Australia, CASA, as the national airworthiness authority, assesses ADs issued by the State of Design and, if necessary, issues corresponding Australian ADs. The Civil Aviation Act 1988 and associated regulations apply to aircraft registered in Australia, and the issuance, assessment, and cancellation of ADs are integral to maintaining safety standards in civil aviation. In this instance, CASA has cancelled Australian AD/BEECH 95/10 for Beechcraft 95 model aircraft, effective from 31 July 2008, as the unsafe condition no longer exists, without the need for a replacement AD or public consultation.
Key Provisions
The Civil Aviation Act 1988, in particular section 98, empowers the Governor-General to establish regulations for the Act, ensuring the safety of air navigation. Under regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) is authorised to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. This regulation highlights that an AD is considered a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and consequently, a legislative instrument as per section 6 of the Legislative Instruments Act 2003.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 are significant. The State of Design, which is the country where an aircraft type is designed, has the primary responsibility for the continuing airworthiness of the aircraft type and must provide necessary information to the States of Registry. The State of Registry, which is the country where the aircraft is registered, must develop or adopt requirements to ensure the continuing airworthiness of aircraft. CASA, as Australia's national airworthiness authority, is tasked with assessing information from the State of Design and, if necessary, issuing an Australian AD to enforce the requirements of the State of Design. This ensures that all aircraft registered in Australia comply with international safety standards.
Failure to comply with the airworthiness directives can lead to various legal consequences. Under the Civil Aviation Act 1988, non-compliance with ADs can result in significant penalties. The specific penalties for breach of ADs are not detailed in the provided text but typically include both civil and criminal sanctions. Civil penalties might include fines, while criminal penalties could involve imprisonment, reflecting the serious nature of ensuring aviation safety. The exact penalties would be determined based on the severity of the breach and any resultant harm or risk.
The process of issuing and cancelling ADs, as exemplified by the case of AD/BEECH 95/10 affecting Beechcraft 95 model aircraft, illustrates the dynamic nature of aviation safety regulations. CASA assessed the AD and determined that the unsafe condition it addressed no longer existed, leading to the cancellation of the directive. This cancellation, effective from 31 July 2008, was made in accordance with the legislative framework provided by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998. The decision to cancel the AD was influenced by Australia's obligations under the Convention on International Civil Aviation, which governs international standards and practices for airworthiness.
