Overview

The Airworthiness Directives 2004, enacted by David Alan Villiers as the delegate of the Civil Aviation Safety Authority, aim to ensure the continued safety of British Aerospace BAe 125 Series Aeroplanes by revoking and remaking existing Airworthiness Directives. The Civil Aviation Safety Authority is tasked with ensuring the safety of civil aviation, and these directives form part of that mandate. This legislative instrument facilitates the updating of safety regulations to address any identified issues and ensure compliance with current safety standards. Each directive in Schedule 1 is re-made in the same form as it appears in the latest published edition, ensuring that all stakeholders are operating under the most recent safety requirements.

Scope and Application

The Airworthiness Directives 2004, made under the authority of the Civil Aviation Safety Authority (CASA) and pursuant to subregulation 39.001(1) of the Civil Aviation Safety Regulations 1998, applies to the British Aerospace BAe 125 Series Aeroplanes. These directives cover a wide range of modifications and inspections to ensure the ongoing airworthiness of the aircraft. They mandate specific actions such as modifications to flight control castings, fuselage frame, aileron shroud clearance, cabin pressure safety, and more, as detailed in the schedules attached to the legislative instrument. Each directive is re-made in the same form as it appears in the latest published edition, ensuring compliance with current safety standards. The geographic reach of these directives is national, applying across Australia, and they are applicable to any entity or person involved in the operation or maintenance of the specified aircraft series within Australian jurisdiction. There are no stated exclusions, exemptions, or thresholds specified in the legislation; thus, the directives apply broadly to all relevant aircraft and operators. Any further extensions or restrictions to the application of these directives may be provided through subordinate instruments issued by CASA.

Key Provisions

The Airworthiness Directives 2004 legislative instrument, issued under subregulation 39.001(1) of the Civil Aviation Safety Regulations 1998, mandates the revocation and remaking of specific Airworthiness Directives for British Aerospace BAe 125 Series Aeroplanes. The directive (section 2) revokes the Airworthiness Directives listed in Schedule 1 and replaces them with new versions that are identical to the latest published editions. The new directives address various modifications, inspections, and replacements for components of the BAe 125 Series Aeroplanes, including flight control castings, fuselage frames, aileron shroud clearances, cabin pressure safety, aircraft flight data recorders, and numerous other parts. The obligations imposed by this Act on the parties or entities it governs are primarily centered around ensuring compliance with the specified Airworthiness Directives. These obligations require aircraft operators, maintenance personnel, and other relevant entities to adhere to the detailed modifications, inspections, and replacements outlined in the directives. This includes ensuring that all components are modified or inspected as specified, and that any necessary replacements are carried out in a timely manner to maintain the airworthiness of the BAe 125 Series Aeroplanes. Furthermore, operators and maintainers must ensure that all modifications and inspections are documented accurately and that records are kept up to date in accordance with the directives. Breaches of the requirements set forth in the Airworthiness Directives 2004 can lead to serious civil and criminal consequences. Under Australian law, failure to comply with airworthiness directives can result in significant penalties, including fines and imprisonment. The maximum penalty for an individual who breaches a civil aviation regulation can be substantial, potentially reaching thousands of Australian dollars. Additionally, corporate entities can face even higher fines. In more severe cases, where non-compliance leads to accidents or endangers flight safety, criminal charges may be brought against responsible individuals or entities, resulting in more severe penalties. The exact penalties can vary based on the severity of the breach and the specific provisions of the Civil Aviation Safety Regulations 1998, but the overarching intent is to ensure that all aircraft operated under these directives maintain the highest standards of safety and airworthiness.
