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, the Civil Aviation Safety Authority (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.
CASA or its predecessors issued AD/TSA-600/1 Amdt 1 affecting Aerostar aircraft with pilots’ seats from a nominated manufacturer. CASA has reviewed this AD and as a result has cancelled it. The cancellation will become effective on 4 June 2009. No replacement AD is required.
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, enacted by the Australian Parliament, establishes the legal framework for ensuring the safety of air navigation. In this context, the Civil Aviation Safety Regulations 1998 empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives are crucial for maintaining the continuing airworthiness of aircraft and are a legislative instrument under the Legislative Instruments Act 2003. The ADs align with international standards set forth by the International Civil Aviation Organization (ICAO), particularly under Annex 8, which assigns the State of Design the responsibility for the continuing airworthiness of an aircraft type and the State of Registry for individual aircraft. CASA's role includes issuing and cancelling ADs to meet these obligations, as evidenced by the recent cancellation of AD/TSA-600/1 Amdt 1 for Aerostar aircraft, reflecting Australia's commitment to international aviation safety standards.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, 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 directives are legislative instruments, subject to disallowance and oversight under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The scope of these directives is grounded in international standards, particularly Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design the responsibility for the continuing airworthiness of an aircraft type and the State of Registry the responsibility for the individual aircraft. CASA, acting in accordance with these international obligations, issued and subsequently cancelled AD/TSA-600/1 Amdt 1, affecting Aerostar aircraft with pilots’ seats from a nominated manufacturer, effective from 4 June 2009. This cancellation aligns with Australia's international commitments and did not require public consultation or a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Safety Regulations 1998 (Regulation 39.001) grant the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs serve as critical regulatory instruments designed to ensure the continued safety and airworthiness of aircraft in accordance with the Civil Aviation Act 1988 (section 98). The ADs are issued under the purview of the State of Design, which has the overarching responsibility for the continuing airworthiness of an aircraft type, as stipulated in Annex 8 to the Convention on International Civil Aviation. Additionally, the State of Registry of an individual aircraft holds responsibility for ensuring the ongoing airworthiness of that aircraft.
Under these regulations, CASA has the authority to issue ADs that mandate specific actions or conditions for maintaining the airworthiness of aircraft. For instance, an AD may require aircraft operators to perform specific maintenance tasks, replace certain parts, or adhere to particular operational procedures. Compliance with these directives is mandatory for all parties governed by the Civil Aviation Safety Regulations 1998. Failure to adhere to the requirements set out in an AD can lead to serious safety implications, and thus, it is crucial for all relevant parties, including aircraft manufacturers, operators, and maintenance providers, to ensure strict compliance.
The Act imposes significant obligations on the parties it governs. Aircraft operators, for example, are required to follow the ADs issued by CASA, which may include conducting inspections, making repairs, or modifying aircraft configurations. Non-compliance with these directives can result in severe consequences, including potential grounding of aircraft, fines, and even criminal charges. Furthermore, the State of Registry is obligated to enforce and oversee compliance with ADs within its jurisdiction, ensuring that all aircraft meet the necessary safety standards. CASA, in its regulatory capacity, must also ensure that ADs are issued in accordance with international standards and obligations under the Convention on International Civil Aviation.
In terms of penalties and consequences for non-compliance, the Civil Aviation Safety Regulations 1998 outline severe repercussions for breaches of ADs. Violations can result in substantial fines, with the maximum penalty varying depending on the nature and severity of the breach. Additionally, persistent or egregious non-compliance can lead to criminal charges, including imprisonment. CASA has the authority to take enforcement actions, such as imposing fines, suspending or revoking airworthiness certificates, or initiating legal proceedings against non-compliant entities. These measures underscore the importance of adhering to ADs and the serious ramifications that can arise from failure to comply.
