Overview

The Airworthiness Directives 2004, made by David Alan Villiers, a delegate of the Civil Aviation Safety Authority (CASA) under the authority granted by the Civil Aviation Safety Regulations 1998, addresses the need to revoke and re-make certain airworthiness directives to ensure continued compliance with current safety standards. This legislative instrument was introduced to maintain and enhance aviation safety by updating or cancelling directives that no longer meet current regulatory requirements or have been superseded by more recent directives. The policy objective is to ensure that all airworthiness directives remain effective and relevant, thereby safeguarding the safety of aircraft operations in Australia. Each directive in the schedule is re-made in exactly the same form as it appears in the latest published edition, ensuring that all stakeholders are informed of the most current safety requirements.

Scope and Application

The Airworthiness Directives 2004, promulgated by David Alan Villiers, acting as a delegate of the Civil Aviation Safety Authority under subregulation 39.001 (1) of the Civil Aviation Safety Regulations 1998, pertains to the revocation and remaking of specific airworthiness directives affecting Schweizer (Grumman) G-164 (Ag-Cat) Series Aeroplanes. These directives apply to the entities and persons responsible for the maintenance, operation, and compliance of these aircraft, ensuring adherence to safety standards and regulatory requirements. The legislation's scope is national, as it concerns civil aviation activities within Australia, impacting various stakeholders in the aviation industry, including aircraft manufacturers, operators, maintenance providers, and pilots. The directives provide detailed instructions and requirements for specific modifications and inspections of the aircraft, ensuring they meet safety and airworthiness criteria. The application of these directives is comprehensive and mandatory for the specified aircraft types, with no exclusions or exemptions outlined in the text. The legislative instrument extends its reach through subordinate instruments, as evidenced by the detailed schedules and specific amendments listed in the document.

Key Provisions

The Airworthiness Directives 2004, under the authority of David Alan Villiers as a delegate of the Civil Aviation Safety Authority (CASA), primarily involve the revocation and re-making of specified Airworthiness Directives (ADs) for Schweizer (Grumman) G-164 (Ag-Cat) series aeroplanes. Section 1 of the legislation mandates the revocation of the listed ADs, as detailed in Schedule 1, and the subsequent re-making of each of these directives as separate instruments. The directives being re-made are listed in Schedule 1, which includes AD/G164/1 through AD/G164/21, with some amendments and modifications as noted. In terms of obligations and requirements, the Act imposes strict adherence to the re-made ADs on the entities governed by these directives. These ADs are critical as they detail specific maintenance, inspection, and modification requirements for various parts of the Schweizer (Grumman) G-164 (Ag-Cat) aeroplanes, ensuring their airworthiness. For example, AD/G164/1 requires a Hopper Load Jettison Requirement, while AD/G164/2 mandates Spray Pump Fan Armour Plates Modification. Each directive specifies the components that must be inspected, modified, or replaced to maintain the aircraft's safety standards. The Act also outlines the consequences for non-compliance with these directives. Section 2 of the Civil Aviation Safety Regulations 1998, under which this legislation operates, provides that failure to comply with an AD can result in severe penalties. Civil penalties can include fines and potential legal actions. Under section 39.001 of the Civil Aviation Safety Regulations 1998, the maximum penalty for non-compliance can amount to significant fines, with the exact amount depending on the severity and frequency of the offence. Additionally, criminal penalties may apply, leading to prosecution, imprisonment, or both, depending on the circumstances of the breach. Compliance with these ADs is crucial for maintaining the safety and airworthiness of the aircraft, and non-compliance can have serious legal repercussions for the operators and owners of these aeroplanes.
