Overview

The Airworthiness Directives 2004, enacted in 2004, was introduced to ensure the safety of airworthiness directives concerning the Pilatus Britten Norman BN2A Mk III (Trislander) Series Aeroplanes. This legislative instrument was created by David Alan Villiers, a delegate of the Civil Aviation Safety Authority, under subregulation 39.001 (1) of the Civil Aviation Safety Regulations 1998. The policy objective of the Airworthiness Directives 2004 is to revoke existing airworthiness directives and re-make them as separate instruments in order to maintain consistency and clarity within the regulations. The attached airworthiness directives focus on various aspects of the aircraft's design, including inspection, modification, and replacement of specific components to ensure the continued safety of the aircraft in operation. Each airworthiness directive within the Airworthiness Directives 2004 is re-made in exactly the same form as it appears in the latest published edition, ensuring that the regulations are up-to-date and easily accessible to industry professionals. By revoking and re-making these directives, the Civil Aviation Safety Authority aims to provide a comprehensive and consistent set of safety requirements for the Pilatus Britten Norman BN2A Mk III (Trislander) Series Aeroplanes, ultimately contributing to the overall safety of Australia's aviation industry.

Scope and Application

The Airworthiness Directives 2004 is a legislative instrument issued by the Civil Aviation Safety Authority (CASA) under the authority of the Civil Aviation Safety Regulations 1998. This Act applies to the Pilatus Britten Norman BN2A Mk III (Trislander) series aeroplanes, and it outlines specific airworthiness requirements and modifications that must be undertaken on these aircraft to ensure their safe operation. The geographic and jurisdictional reach of this Act is national, as it applies throughout Australia, enforced by CASA, a Commonwealth authority. This instrument revokes existing Airworthiness Directives and re-makes them in identical form, ensuring consistency and clarity in the regulatory framework governing the airworthiness of the specified aircraft. The Act does not explicitly state any exclusions or exemptions, implying that all aircraft within the scope of the legislation must comply with the outlined requirements. The application of the Act may be extended or restricted through subordinate instruments, which may provide further details or clarifications on specific aspects of the airworthiness directives.

Key Provisions

The legislative instrument F2006B07945, titled "Airworthiness Directives 2004," primarily serves to revoke certain Airworthiness Directives and remake them as separate instruments. This is detailed in the instrument issued by David Alan Villiers, the delegate of the Civil Aviation Safety Authority (CASA) under subregulation 39.001 (1) of the Civil Aviation Safety Regulations 1998. The revocation and remaking of Airworthiness Directives are outlined in Schedule 1, which lists specific directives related to Pilatus Britten Norman BN2A Mk III (Trislander) Series Aeroplanes. Each directive is being re-made in the same form as it appears in the latest published edition. The obligations imposed by the Act primarily pertain to aircraft manufacturers, operators, and maintenance organisations. They are required to adhere to the specific requirements outlined in the Airworthiness Directives, which include inspections, modifications, and replacements of various aircraft components. These requirements are designed to ensure the safety and airworthiness of the Pilatus Britten Norman BN2A Mk III (Trislander) Series Aeroplanes. Compliance with these directives is essential for maintaining the aircraft's certification and ensuring safe operation. Breaches of the Airworthiness Directives can lead to significant legal consequences. The Civil Aviation Safety Regulations 1998 provides a framework for enforcement, and non-compliance can result in civil or criminal penalties. For instance, failure to adhere to the directives may result in the grounding of the aircraft, which can have substantial operational and financial repercussions for the operators. Additionally, serious breaches may lead to criminal charges, with potential penalties including fines and imprisonment, as stipulated by the relevant aviation regulations. The specific penalties depend on the severity and impact of the non-compliance.
