Overview

The Airworthiness Directives 2004 were enacted to address the need for a comprehensive and updated regulatory framework governing the airworthiness of aircraft in Australia. This legislative instrument, issued by David Villiers as the delegate of the Civil Aviation Safety Authority, revokes existing airworthiness directives and remakes them to ensure consistency with the latest safety standards. The policy objective behind these directives is to maintain the highest levels of safety in civil aviation by ensuring that aircraft meet specific technical and operational standards. By remaking the airworthiness directives, the Civil Aviation Safety Authority aims to provide clear and updated guidance to aircraft owners and operators, thereby enhancing the overall safety of the national airspace.

Scope and Application

The Airworthiness Directives 2004, issued by the delegate of the Civil Aviation Safety Authority (CASA), specifically David Alan Villiers, under subregulation 39.001 (1) of the Civil Aviation Safety Regulations 1998, are designed to revoke and re-make certain Airworthiness Directives that pertain to the airworthiness of Embraer EMB-120 Brasilia Series aeroplanes. These directives are applicable to aircraft operators and maintenance providers within Australia and those operating Australian-registered aircraft abroad. The scope of the directives includes detailed instructions and requirements to ensure the ongoing airworthiness of these specific aircraft models, addressing various components and systems such as the generator control unit, autopilot disengagement logic, and electrical power systems. The geographic reach of these directives is national, impacting all entities involved in the operation and maintenance of the specified aircraft within Australia. Notably, the directives provide specific exclusions and amendments where applicable, ensuring that only relevant and necessary changes are implemented. The authority to extend or restrict the application of these directives is granted through subordinate instruments, allowing CASA to make precise and targeted amendments as necessary to maintain safety standards.

Key Provisions

The Airworthiness Directives 2004 legislative instrument primarily focuses on the revocation and remaking of various Airworthiness Directives (ADs) related to the Embraer EMB-120 (Brasilia) series aeroplanes. The key sections of the instrument (sections 1 and 2) revoke the specified Airworthiness Directives listed in Schedule 1 and then re-make each of these directives as separate instruments. The re-made directives are in the exact form as they appear in the latest published edition of the directive. This ensures that the ADs are updated and reflect the most current safety and regulatory requirements. Under the Airworthiness Directives 2004, the obligations imposed on the parties governed by these directives are significant. These include adherence to the specific requirements outlined in each Airworthiness Directive. Operators of the Embraer EMB-120 (Brasilia) series aeroplanes must ensure compliance with the detailed instructions and modifications mandated by the ADs. This could involve various tasks such as installing new components, modifying existing systems, conducting inspections, and making repairs. Failure to comply with these directives can result in serious safety hazards and potential non-compliance with aviation regulations. The Airworthiness Directives 2004 also stipulates consequences for non-compliance with the ADs. Breaching any of the requirements outlined in the re-made directives can lead to civil and criminal penalties. The maximum penalties for such breaches are substantial, reflecting the critical importance of adhering to airworthiness standards. Civil penalties can include fines, while criminal penalties may involve imprisonment. The exact penalties depend on the severity of the breach and the specific regulations violated. Enforcement of these penalties is a crucial aspect of ensuring that all parties maintain the required airworthiness standards. In summary, the Airworthiness Directives 2004 instrument plays a vital role in maintaining the safety and regulatory compliance of the Embraer EMB-120 (Brasilia) series aeroplanes. By revoking outdated directives and re-making them with the latest safety requirements, the legislation ensures that all operators adhere to stringent standards. The obligations placed on the governed parties are clear and detailed, and the consequences for non-compliance are severe, underscoring the importance of strict adherence to these directives.
