AD/AS 355/24 Amdt 2 - Consolidation of Early Airworthiness Directives

Overview

The Civil Aviation Regulations 1998, amended under the authority of the Civil Aviation Act 1988, addresses the need for streamlined and consolidated airworthiness directives to ensure the safety of civil aviation operations. This particular legislative instrument, F2006B02479, targets the Eurocopter AS 355 (Twin Ecureuil) Series Helicopters and consolidates previous airworthiness directives to simplify compliance for operators. The amendment aims to reduce the administrative burden on operators while maintaining the high safety standards required by the Civil Aviation Safety Authority. It achieves this by retaining a one-time inspection of the engine firewalls, deleting outdated service bulletins, and reissuing necessary directives to ensure continued safety and efficiency in air operations. The Civil Aviation Regulations 1998 were enacted by the Parliament of Australia to regulate civil aviation safety, ensuring that aircraft meet specific airworthiness standards. The policy objective of this particular amendment is to streamline regulatory requirements and reduce the administrative burden on operators, while maintaining the integrity and safety of aircraft operations. By consolidating early airworthiness directives, the Civil Aviation Safety Authority seeks to provide clear and efficient guidance to operators, ensuring compliance with safety standards without unnecessary duplication or complexity.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, which pertains to the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, applies to all Eurocopter AS 355 (Twin Ecureuil) Series Helicopters. This legislation mandates compliance with Aerospatiale AS 355 SB 71-04 as part of the regulatory framework ensuring the airworthiness of these aircraft. The directive is intended to streamline the inspection process by consolidating previous directives, thereby reducing the administrative burden on operators. Notably, SB 71-08 has been deleted from the current requirements, while SB 05-02 has been reissued as AD/AS 355/36. These directives must be adhered to prior to the issuance of a Certificate of Airworthiness, underscoring the importance of maintaining stringent safety standards in the operation of these helicopters. The scope of this regulation is geographically limited to the Commonwealth of Australia, enforcing compliance among all entities operating Eurocopter AS 355 helicopters within Australian airspace. This includes both commercial and private operators, ensuring that all such aircraft meet the stipulated airworthiness criteria. There are no specified exclusions, exemptions, or thresholds within the text provided, indicating a broad application across the specified aircraft models. The effectiveness and reach of these directives may be further elaborated or adjusted through subordinate instruments, which may provide additional technical specifications or procedural details to support the overarching requirements outlined in the Civil Aviation Regulations.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, outlines the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives for the Eurocopter AS 355 (Twin Ecureuil) Series Helicopters, as detailed in AD/AS 355/24 Amendment 2. This regulation consolidates earlier airworthiness directives, including SB 71-04, and applies to all models of the specified helicopters. The primary requirement under this directive is that operators must ensure their aircraft comply with Aerospatiale AS 355 SB 71-04 before issuing a Certificate of Airworthiness. This consolidation aims to streamline and reduce the administrative burden on operators by consolidating necessary inspections and directives. Operators of Eurocopter AS 355 (Twin Ecureuil) Series Helicopters must adhere to specific obligations as stipulated by the Civil Aviation Regulations 1998. Primarily, these obligations include conducting a one-time inspection of the engine fire walls to ensure compliance with the requirements set forth in Aerospatiale AS 355 SB 71-04. This inspection must be completed prior to the issuance of a Certificate of Airworthiness. Additionally, certain earlier service bulletins, such as SB 71-08, have been removed from the consolidated directive, while others, like SB 05-02, have been reissued as a separate Airworthiness Directive (AD/AS 355/36). This reorganisation aims to simplify compliance processes for operators, ensuring they focus on the most critical and current directives. Failure to comply with the airworthiness directives specified in the Civil Aviation Regulations 1998 can result in serious legal and safety consequences. Operators who do not adhere to the requirements of AD/AS 355/24 Amendment 2, particularly the mandated inspection of engine fire walls, may face significant repercussions. The Civil Aviation Act 1988 provides for various penalties, including fines and potential imprisonment, for non-compliance with airworthiness directives. The exact penalties can vary based on the severity and circumstances of the breach, but the overarching aim is to enforce strict compliance to ensure the highest safety standards in civil aviation.
