Airworthiness Directives 2004 - Revocation and Remaking - Pilatus Porter PC-6 Series Aeroplanes

Overview

The Airworthiness Directives 2004, enacted on 20 December 2004, address the need for the Civil Aviation Safety Authority (CASA) to ensure the safety and airworthiness of Pilatus Porter PC-6 Series aeroplanes by updating and revoking outdated directives. The Civil Aviation Safety Regulations 1998 empower CASA to delegate authority to David Alan Villiers, who, in this instance, revoked existing airworthiness directives and remade them as separate instruments, each corresponding to the latest published editions. The policy objective is to maintain a current and effective regulatory framework that ensures the highest standards of safety and airworthiness are upheld in the aviation industry. This legislative instrument, issued by David Alan Villiers as the delegate of CASA, aims to streamline and modernise the airworthiness directives for Pilatus Porter PC-6 Series aeroplanes, ensuring that all safety-related instructions are current and enforceable. The directives cover a wide range of modifications and inspections, from propeller pitch control and air intake heating to elevator assembly and rudder modifications, reflecting CASA's commitment to continuous improvement in aviation safety standards.

Scope and Application

The Airworthiness Directives 2004, issued under the authority of the Civil Aviation Safety Regulations 1998, apply specifically to the Pilatus Porter PC-6 Series Aeroplanes. These directives are aimed at ensuring the safety and airworthiness of the specified aircraft by mandating modifications, inspections, and replacements of various components. The scope of this legislation encompasses all aircraft of the Pilatus Porter PC-6 Series operating within Australia, thereby affecting aircraft owners, operators, and maintenance personnel who must comply with these directives. The directives are not limited by geographic boundaries within Australia and apply to both Commonwealth and state jurisdictions. Notably, the legislation does not specify any exclusions, exemptions, or thresholds; however, it does extend its application through the subordinate instruments, which are detailed in the schedules attached to the directives. Each directive is re-made in the same form as it appears in the latest published edition, ensuring consistency and clarity in the mandated safety requirements.

Key Provisions

The Airworthiness Directives 2004, made by David Alan Villiers, delegate of the Civil Aviation Safety Authority, under subregulation 39.001(1) of the Civil Aviation Safety Regulations 1998, primarily serve to revoke existing Airworthiness Directives and remake them in a new form. This legislative instrument addresses specific issues with Pilatus Porter PC-6 Series aeroplanes, including modifications and inspections on various components such as the rudder, ailerons, propeller pitch control, air intake heating, and other structural parts. Each directive is re-made exactly as it appears in the latest published edition, ensuring the directives remain current and effective. The main sections of this instrument are sections 1 and 2, which outline the revocation and remaking of the directives, and Schedule 1, which lists the specific directives being revoked and remade. Under this legislation, the Civil Aviation Safety Authority imposes obligations on aircraft operators, maintenance personnel, and other relevant parties to comply with the re-made Airworthiness Directives. These directives mandate specific actions to ensure the airworthiness of Pilatus Porter PC-6 Series aeroplanes. For instance, operators must follow the detailed inspection and modification procedures outlined in the directives for components such as the rudder, ailerons, and fuel systems. Maintenance personnel are required to adhere strictly to the prescribed methods and timelines for carrying out these inspections and modifications. Failure to comply with these directives could result in the aircraft being deemed unairworthy, which could lead to severe operational disruptions and safety risks. The Airworthiness Directives 2004 also include provisions for potential civil and criminal penalties for non-compliance. While specific penalties are not detailed within the text, breaches of the Civil Aviation Safety Regulations 1998, which underpin these directives, can result in substantial fines and, in severe cases, imprisonment. For example, under section 48 of the Civil Aviation Act 1988, individuals found guilty of recklessly causing a dangerous situation in an aircraft can face imprisonment for up to two years. Additionally, operators and maintenance personnel who fail to comply with the airworthiness directives can face fines and other enforcement actions, including potential revocation of their operating certificates. These penalties underscore the importance of strict adherence to the directives to maintain the highest safety standards in aviation.
