Overview

The Airworthiness Directives 2004 was enacted to address the need for updating and ensuring the safety and airworthiness of Mitsubishi MU-2 Series Aeroplanes, which is essential for maintaining public confidence in air travel and ensuring the safety of passengers and crew. This legislative instrument was issued by David Alan Villiers, the delegate of the Civil Aviation Safety Authority, acting under the authority of subregulation 39.001 (1) of the Civil Aviation Safety Regulations 1998. The policy objective of this instrument is to revoke existing airworthiness directives that may no longer be relevant or effective, and to re-make them in their current form to ensure that they continue to provide necessary safety measures for the operation of Mitsubishi MU-2 Series Aeroplanes. This ensures that the aircraft maintain their airworthiness and continue to meet the safety standards set by the Civil Aviation Safety Authority.

Scope and Application

The Airworthiness Directives 2004, issued by the delegate of the Civil Aviation Safety Authority under the Civil Aviation Safety Regulations 1998, apply to Mitsubishi MU-2 series aeroplanes and mandate specific modifications and inspections to ensure compliance with airworthiness standards. These directives cover various aspects of the aircraft's structure, systems, and components, including the lagging of engine air bleed pipes, modifications to windows, inspection of fuel vent check valves, and limitations on wing structural fatigue, among others. The scope of these directives is national, applying across Australia, and they are enforced through the revocation and remaking of specific airworthiness directives as listed in Schedule 1. Each directive is re-made in exactly the same form as it appears in the latest published edition. The application of these directives is not restricted by any stated exclusions, exemptions, or thresholds, and their enforcement may be further extended or restricted through subordinate instruments made under the authority of the Civil Aviation Safety Regulations 1998.

Key Provisions

The Airworthiness Directives 2004, issued under the authority of the Civil Aviation Safety Authority (CASA), involve the revocation and re-making of several Airworthiness Directives related to the Mitsubishi MU-2 Series aeroplanes. This legislative instrument, issued by David Villiers as the delegate of CASA, primarily serves to ensure that the specified aircraft comply with updated safety standards and regulatory requirements. The Airworthiness Directives outlined in Schedule 1, which pertain to various components and systems of the Mitsubishi MU-2 Series aeroplanes, are revoked and subsequently re-made as individual instruments. Each re-made directive is identical to the latest published version, ensuring that all stakeholders have access to the most current safety mandates. These Airworthiness Directives impose specific obligations on aircraft operators, maintenance providers, and other relevant parties. For example, they mandate detailed inspections, modifications, and replacements of various aircraft components to address safety concerns and compliance with regulatory standards. Operators and maintenance personnel must adhere to the prescribed procedures and timelines for implementing these directives to maintain the airworthiness of the Mitsubishi MU-2 Series aeroplanes. Failure to comply with these requirements could result in significant safety risks and non-compliance with aviation regulations. Breaching the obligations set forth in these Airworthiness Directives can lead to serious consequences. Civil penalties may be imposed for non-compliance, with the specific penalties varying depending on the nature and severity of the breach. In more severe cases, where non-compliance results in a safety hazard, criminal penalties may apply. The potential criminal penalties include fines of up to $210,000 for individuals and $1,050,000 for corporations, as well as imprisonment terms. The exact penalties are determined by the courts, taking into account the specific circumstances of the breach and any mitigating or aggravating factors.
