Overview

The Airworthiness Directives 2004 were enacted by David Alan Villiers, as a delegate of the Civil Aviation Safety Authority, under the authority granted by the Civil Aviation Safety Regulations 1998. This legislative instrument was introduced to address the need for updated and consolidated airworthiness directives for specific Cessna aircraft models, namely the 170, 172, F172, FR172, and 175 series aeroplanes. The directives aim to ensure that these aircraft maintain their airworthiness by addressing various safety concerns and specifying required maintenance and operational procedures. The enactment by the Civil Aviation Safety Authority reflects the regulatory body's commitment to ensuring that aviation safety standards are met and that the public is protected by maintaining the highest standards of aircraft safety.

Scope and Application

The Airworthiness Directives 2004, made by David Alan Villiers, the delegate of the Civil Aviation Safety Authority, under the authority of subregulation 39.001(1) of the Civil Aviation Safety Regulations 1998, primarily applies to the aircraft industry, particularly to those involved in the maintenance, operation, and airworthiness compliance of Cessna 170, 172, F172, FR172, and 175 Series aeroplanes. This legislation ensures that the aircraft meet specific safety standards and operational requirements. It encompasses the conduct and transactions associated with the airworthiness of these aircraft models, ensuring that all relevant parties adhere to the outlined directives. The scope of this Act is national, as it operates under the authority of the Commonwealth and applies across all states and territories in Australia. There are no specific exclusions, exemptions, or thresholds mentioned within the text; however, the application and enforcement of these directives are subject to the broader regulatory framework of the Civil Aviation Safety Regulations 1998. The Act also notes that each Airworthiness Directive is being remade in exactly the same form as appears in the latest published edition of the Directive, ensuring consistency and clarity in regulatory standards.

Key Provisions

The Airworthiness Directives 2004 legislative instrument, enacted by David Alan Villiers as a delegate of the Civil Aviation Safety Authority (CASA), includes the revocation of existing Airworthiness Directives (AD) and their re-making as separate instruments. The document lists specific ADs for Cessna 170, 172, F172, FR172, and 175 series aeroplanes, noting which directives are cancelled and which remain active. Each re-made directive is identical to the latest published version. The primary obligation imposed by the Act is the adherence to the re-made Airworthiness Directives by the relevant parties, such as aircraft owners, operators, and maintenance organisations. These directives mandate specific actions and requirements to ensure the airworthiness of the specified Cessna aeroplanes, including maintenance, repairs, and modifications. Compliance with these directives is essential for ensuring the safety and airworthiness of the aircraft in question. Failure to comply with the Airworthiness Directives can result in significant legal consequences. Civil penalties may be imposed for non-compliance, which can include fines or other monetary penalties. Additionally, if non-compliance leads to an accident or incident, the penalties can be more severe. In criminal cases, non-compliance can lead to prosecution under relevant aviation safety legislation, potentially resulting in substantial fines or imprisonment. The exact penalties depend on the severity of the breach and the impact on aviation safety.
