COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
AIRWORTHINESS DIRECTIVE
For the reasons set out in the background section, the CASA delegate whose signature appears below issues the following Airworthiness Directive (AD) under subregulation 39.1 (1) of CAR 1998. The AD requires that the action set out in the requirement section (being action that the delegate considers necessary to correct the unsafe condition) be taken in relation to the aircraft or aeronautical product mentioned in the applicability section: (a) in the circumstances mentioned in the requirement section; and (b) in accordance with the instructions set out in the requirement section; and (c) at the time mentioned in the compliance section.
British Aerospace BAe 146 Series Aeroplanes
AD/BAe 146/89 Vickers Standby Generator 7/2001
Applicability: All BAe 146 100, 200 and 300 series aeroplane and all Avro 146-RJ70, RJ85 and RJ100 series aeroplanes with Modification HCM01059A incorporated.
Requirement: Incorporate Modification HCM01691A in accordance with BAe Systems (Operations) Limited Service Bulletin SB.24-137-01691A dated 12 April 2001.
Note: This Service Bulletin has been classified as Mandatory by the CAA(UK).
Compliance: Before 31 December 2004.
This Airworthiness Directive becomes effective on 12 July 2001.
Background: BAe has reported that the composite armature banding rings on the standby generator have been found to delaminate after prolonged operation at high temperature.
Vickers, the standby generator manufacturer, has introduced a replacement generator with banding rings manufactured from titanium.
This Directive requires incorporation of Modification HCM01691A which replaces standby generator part number (P/N) 520829 with P/N 3022049-000.

Delegate of the Civil Aviation Safety Authority 21 May 2001
The above AD is notified in the Commonwealth of Australia Gazette on 13 June 2001.
Overview
The Civil Aviation Regulations 1998, specifically Part 39 - 105, addresses safety concerns associated with aircraft and aeronautical products through Airworthiness Directives. This legislation was enacted to ensure the safety of aviation operations by mandating corrective actions when unsafe conditions are identified. In this particular instance, the Civil Aviation Safety Authority (CASA) has issued an Airworthiness Directive (AD) for the British Aerospace BAe 146 Series Aeroplanes, aiming to address an identified issue with the Vickers Standby Generator. The directive, AD/BAe 146/89, requires the incorporation of a specific modification (HCM01691A) to rectify the unsafe condition caused by the delamination of composite armature banding rings in the standby generator due to high-temperature operation. The policy objective here is to ensure that all affected aircraft are modified to prevent potential safety hazards, thereby maintaining the highest safety standards in civil aviation.
Scope and Application
This Airworthiness Directive (AD) issued by the Civil Aviation Safety Authority (CASA) under the Civil Aviation Regulations 1998 (CAR) applies specifically to all BAe 146 100, 200, and 300 series aeroplanes, as well as all Avro 146-RJ70, RJ85, and RJ100 series aeroplanes that have incorporated Modification HCM01059A. The directive mandates that a particular action must be taken to address a safety concern related to the Vickers standby generator. The requirement is to incorporate Modification HCM01691A, as specified in BAe Systems (Operations) Limited Service Bulletin SB.24-137-01691A dated 12 April 2001, which replaces a particular generator part with a new one manufactured from titanium. This modification is necessary to rectify an issue where the composite armature banding rings of the standby generator have been observed to delaminate after prolonged operation at high temperatures. The directive is effective as of 12 July 2001 and must be complied with before 31 December 2004, as published in the Commonwealth of Australia Gazette on 13 June 2001.
Key Provisions
The Civil Aviation Regulations 1998, specifically under Part 39 - 105, provide detailed provisions concerning Airworthiness Directives (ADs) issued by the Civil Aviation Safety Authority (CASA). These ADs are regulatory mandates aimed at ensuring the safety of aircraft by addressing potential safety issues identified with specific aircraft or aeronautical products. The key sections of this legislation, such as section 39.1(1), empower the CASA delegate to issue these directives. For instance, in the provided AD/BAe 146/89, the delegate issues an AD for the Vickers Standby Generator, requiring modifications to address a safety issue identified with the composite armature banding rings on the standby generator.
Under this Act, specific obligations and requirements are imposed on the entities governed by it. For example, in the case of AD/BAe 146/89, all BAe 146 100, 200, and 300 series aeroplanes, as well as all Avro 146-RJ70, RJ85, and RJ100 series aeroplanes with Modification HCM01059A incorporated, must incorporate Modification HCM01691A. This modification involves replacing the standby generator part number (P/N) 520829 with P/N 3022049-000, as outlined in the requirement section. This action must be taken before 31 December 2004, ensuring that the directive is implemented within the specified timeframe.
The legislation also outlines potential consequences for non-compliance with the ADs. While specific penalties are not detailed in the provided text, breaches of ADs can generally lead to both civil and criminal consequences. Civil penalties may include fines, while criminal penalties could result in imprisonment. The severity of these penalties can vary depending on the nature and extent of the breach, as well as the potential risk to aviation safety posed by the non-compliance. Ensuring adherence to these directives is crucial for maintaining the highest safety standards in civil aviation.
