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/BEECH 55/58, affecting Beech 55 model aircraft in 1980. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 5 June 2008. No replacement AD is required, all affected aircraft would have been inspected, and, if necessary, modified long ago.
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 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, enacted by the Parliament of Australia, was established to regulate civil aviation safety in the country, aiming to ensure the safety of air navigation and public safety. In conjunction with this Act, the Civil Aviation Safety Regulations 1998 provide the regulatory framework governing airworthiness, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These ADs are legislative instruments issued under the authority of the Act to maintain the continuing airworthiness of aircraft. The objective of ADs is to address safety concerns and ensure compliance with safety standards for specific aircraft types or aeronautical products.
The Civil Aviation Safety Regulations 1998 empower CASA to issue ADs when necessary, and these directives are aligned with the international standards set by the International Civil Aviation Organization (ICAO). In a specific case, CASA has decided to cancel AD/BEECH 55/58, which affected Beech 55 model aircraft, effective from 5 June 2008. This cancellation was based on the assessment that no further action is required as all affected aircraft would have been inspected and modified as needed. The decision to cancel the AD was made without public consultation as it reduces the regulatory burden, and the Office of Best Practice Regulation has determined that such ADs do not require a Regulatory Impact Statement. The AD cancellation was authorised by the Manager, Airframes in the Airworthiness Engineering Branch of CASA, in accordance with the Act.
Scope and Application
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, provides the legislative framework under which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) for certain kinds of aircraft or aeronautical products. This regulatory mechanism is integral to ensuring the continuing airworthiness of aircraft, with CASA, as Australia’s national airworthiness authority, mandated to assess information from the State of Design and, when necessary, issue Australian ADs to enforce the requirements set by the State of Design. The issuance of ADs falls under regulation 39.001 of the Civil Aviation Safety Regulations 1998, which empowers CASA to mandate specific safety measures. These directives are legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003, thereby holding the force of law. The application of these regulations is national, extending across all states and territories in Australia, and aligns with international standards under Annex 8 to the Convention on International Civil Aviation. While ADs typically do not require public consultation due to their specific nature and minimal regulatory burden, they remain a critical tool for maintaining aviation safety standards.
Key Provisions
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, provides a framework for ensuring the safety of air navigation. Under section 98 of the Act, the Governor-General has the authority to make regulations for the purposes of the Act, which includes ensuring the safety of air navigation. Section 39.001 of the Regulations empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These ADs are formal notifications to aircraft owners and operators about safety issues that need to be addressed to maintain the continuing airworthiness of aircraft.
The obligations imposed by these regulations require CASA to issue ADs when necessary to address safety issues. For example, under regulation 39.001(5), an AD is considered a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and thus a legislative instrument. This means CASA must ensure that ADs are issued in accordance with legislative requirements and are properly scrutinised and approved. Additionally, Annex 8 to the Convention on International Civil Aviation places the responsibility of continuing airworthiness on the State of Design, which must provide necessary information to the States of Registry. In Australia, CASA, as the national airworthiness authority, must assess this information and, if appropriate, issue an Australian AD to enforce the requirements of the State of Design.
There are significant consequences for non-compliance with airworthiness directives. Under the Civil Aviation Act 1988, any person who contravenes an AD is subject to enforcement actions. The Act does not explicitly state the penalties for non-compliance, but such violations can lead to serious legal and safety repercussions, including potential fines and the grounding of aircraft. These measures are designed to ensure that aircraft remain airworthy and that safety standards are consistently met. Therefore, entities and individuals governed by these regulations must adhere strictly to the requirements outlined in any ADs issued by CASA.
The Civil Aviation Safety Regulations 1998 also include provisions for the issuance, review, and cancellation of ADs. For instance, CASA issued AD/BEECH 55/58 for Beech 55 model aircraft in 1980, which has now been reviewed and cancelled. The cancellation of this AD, effective from 5 June 2008, was determined not to require consultation with the Australian public due to its minimal regulatory impact. Additionally, the Office of Best Practice Regulation has concluded that ADs do not necessitate a Regulatory Impact Statement. This streamlined process ensures that CASA can efficiently address and resolve safety issues without undue bureaucratic delay.
