COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 106 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Turbomeca Turbine Engines - Arrius Series
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.
AD/ARRIUS/3 Fuel Control Unit 2/2001
Applicability: Arrius 2F turboshaft engines incorporating a fuel control unit (FCU) listed in Turbomeca Alert Service Bulletin A319 73 4808, Issue 1.
Requirement: Rework the FCU maximum fuel flow stop in accordance with Turbomeca Alert Service Bulletin A319 73 4808, Issue 1 or any subsequent issue.
Note: DGAC AD 2000-482 (A) refers.
Compliance: Prior to 30 April 2001.
This Airworthiness Directive becomes effective on 22 February 2001.
Background: This Directive has been issued to require an adjustment of the FCU. The requirement follows advice of a fuel flow limitation being identified during an FCU repair. A fuel flow limitation may prevent maximum certificated engine power being available.

Delegate of the Civil Aviation Safety Authority 16 January 2001
The above AD is notified in the Commonwealth of Australia Gazette on 24 January 2001.
Overview
The Civil Aviation Regulations 1998, as amended, were enacted to establish a comprehensive regulatory framework for civil aviation in Australia, addressing safety, licensing, operations, and other aspects of air navigation. This legislation was introduced to ensure the safety and efficiency of civil aviation in Australia, as well as to harmonise with international standards and practices. The Civil Aviation Regulations 1998 are administered by the Civil Aviation Safety Authority (CASA) under the Civil Aviation Act 1988. The policy objective of these regulations is to ensure the highest possible level of safety in civil aviation while facilitating the growth and development of the aviation industry. This specific Airworthiness Directive, issued under the authority of CASA, is aimed at addressing an identified unsafe condition with Arrius Series turbomeca turbine engines, ensuring that corrective actions are taken to maintain the airworthiness of affected aircraft and mitigate any safety risks.
Scope and Application
The Airworthiness Directive (AD) under the Civil Aviation Regulations 1998 applies specifically to Arrius 2F turboshaft engines that have a fuel control unit (FCU) listed in Turbomeca Alert Service Bulletin A319 73 4808, Issue 1. This directive is issued by a delegate of the Civil Aviation Safety Authority (CASA) and mandates that the FCU maximum fuel flow stop be reworked in accordance with the specified Turbomeca bulletin to correct a condition that could limit fuel flow, thereby preventing the engine from achieving its maximum certified power. The directive is applicable across the Commonwealth of Australia and became effective on 22 February 2001, with compliance required by 30 April 2001. The AD is notified in the Commonwealth of Australia Gazette, ensuring its legal enforceability throughout the nation. No exclusions or exemptions are explicitly stated in the text, implying that all affected engines must adhere to the specified requirements.
Key Provisions
The key sections of the Airworthiness Directive (AD/ARRIUS/3) include the applicability, requirement, and compliance sections. The applicability section (a) specifies that the directive applies to Arrius 2F turboshaft engines that have a fuel control unit (FCU) listed in Turbomeca Alert Service Bulletin A319 73 4808, Issue 1. The requirement section (b) mandates that the FCU maximum fuel flow stop be reworked in accordance with Turbomeca Alert Service Bulletin A319 73 4808, Issue 1 or any subsequent issue. The compliance section (c) sets a deadline of 30 April 2001 for the specified action to be completed.
The AD imposes specific obligations on the entities it governs. Owners and operators of Arrius 2F turboshaft engines must ensure that the FCU maximum fuel flow stop is reworked in line with the specified bulletin. This involves adhering to the instructions provided by Turbomeca, ensuring that any identified fuel flow limitations are corrected to maintain the engine's maximum certificated power. Compliance with this AD is mandatory, and failure to meet the stipulated requirements can lead to significant safety and regulatory repercussions.
Breaches of this Airworthiness Directive may result in serious consequences. While the specific civil or criminal penalties are not detailed within the AD itself, non-compliance with CASA directives generally can lead to enforcement actions. These may include fines, suspension or revocation of aircraft certificates, and potential criminal charges for individuals or corporations responsible for the non-compliance. The exact penalties can vary depending on the severity and impact of the breach but can be significant, reflecting the critical importance of air safety and regulatory compliance in the aviation industry.
