COMMONWEALTH OF AUSTRALIA (Civil Aviation Safety Regulations 1998), PART 39 - 106 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
AIRWORTHINESS DIRECTIVE
On the effective date specified below, and for the reasons set out in the background section, the CASA delegate whose signature appears below revokes Airworthiness Directive (AD) AD/ARRIUS/1 and issues the following AD under subregulation 39.1 (1) of CASR 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.
Turbomeca Turbine Engines - Arrius Series
AD/ARRIUS/1
Amdt 1
Fuel Injection Manifold Replacement 12/2004
TX
Applicability: Arrius 2F engines.
Requirement: Replace the fuel manifolds and carry out repetitive power check in accordance with the procedures of Turbomeca Alert Service Bulletin Number A319 73 4001 Update 3 or later updates as approved by the French DGAC.
Note: DGAC AD 1999-233(A) refers.
Compliance: As detailed in the requirement document or later approved DGAC updates.
This Amendment becomes effective on 15 October 2004.
Background: This directive was issued requiring the initial replacement of fuel injection manifolds and subsequent replacement of fuel injection manifolds found to be defective at the 200 hourly power checks. The requirement reflects advice of blockage of the manifolds that may lead to engine flameout during rapid deceleration.
This Amendment is issued to reflect that later revisions of the original reference document may be used.
The original issue of this Directive became effective on 2 December 1999.
James Coyne
Delegate of the Civil Aviation Safety Authority 14 October 2004
The above AD is notified in the Commonwealth of Australia Gazette on 15 October 2004.
Overview
The Civil Aviation Safety Regulations 1998 (CASR 1998), enacted by the Australian Parliament, provide the legal framework for ensuring the safety of civil aviation within Australia. These regulations were introduced to address the need for a comprehensive and enforceable set of rules governing civil aviation safety. One of the key components of these regulations is Part 39, which includes Airworthiness Directives (ADs) aimed at addressing specific safety issues. ADs, such as AD/ARRIUS/1Amdt 1, are issued by the Civil Aviation Safety Authority (CASA) to ensure that all civil aviation aircraft and products maintain their airworthiness. The primary policy objective of these directives is to mitigate safety risks by mandating corrective actions on identified unsafe conditions. The AD in question, which mandates the replacement of fuel injection manifolds in Arrius 2F engines, reflects the authority's commitment to addressing potential engine flameouts during rapid deceleration, thereby enhancing overall flight safety.
Scope and Application
The Civil Aviation Safety Regulations 1998, specifically PART 39 - 106 Civil Aviation Safety Authority Schedule of Airworthiness Directives, applies to all aircraft or aeronautical products that are subject to the regulations of the Civil Aviation Safety Authority (CASA). In this case, the Airworthiness Directive (AD) AD/ARRIUS/1 Amendment 1 pertains to Arrius 2F engines, which must comply with the directive's requirements for safety purposes. The directive applies to all Arrius 2F engines in operation within Australia, as CASA is the governing body for civil aviation safety throughout the Commonwealth. The directive, however, is specific to the identified engine type and does not extend to other aircraft or aeronautical products unless they fall under the same category of engine. This AD, issued under subregulation 39.1 (1) of CASR 1998, mandates the replacement of fuel injection manifolds and requires a repetitive power check in accordance with specified procedures to address potential unsafe conditions, particularly the risk of engine flameout during rapid deceleration due to manifold blockage. The AD is effective from 15 October 2004, as notified in the Commonwealth of Australia Gazette on the same date.
Key Provisions
The Airworthiness Directive (AD) AD/ARRIUS/1 Amdt 1, issued under the Civil Aviation Safety Regulations 1998 (CASR), specifically targets Arrius 2F engines (section 1). It mandates the replacement of fuel injection manifolds and requires a repetitive power check to be conducted in accordance with the procedures outlined in Turbomeca Alert Service Bulletin Number A319 73 4001 Update 3 or any subsequent approved updates by the French DGAC (sections 2 and 3). This directive was issued due to concerns about potential blockages in the manifolds that could lead to engine flameout during rapid deceleration (section 4).
The AD imposes specific obligations on the holders of aircraft certificates and operators of the affected aircraft. They must ensure that the required actions are taken on the Arrius 2F engines as detailed in the directive (section 1). This includes replacing the fuel injection manifolds and conducting the repetitive power check using the specified procedures (sections 2 and 3). The compliance timeframe is set out in the directive, with the requirement to adhere to the procedures as detailed in the requirement document or any later approved updates (section 4).
Non-compliance with the AD AD/ARRIUS/1 Amdt 1 may result in significant consequences. The Civil Aviation Safety Authority (CASA) has the authority to enforce this directive and may take action against non-compliant aircraft or operators. While the specific penalties for non-compliance are not detailed in the AD itself, it is understood that failure to comply with CASA directives can lead to enforcement actions, including fines and potential grounding of the aircraft until the required actions are completed. The exact penalties and consequences would be determined under the broader provisions of the CASR and other relevant legislation.
