COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 106 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.
CFM International Turbine Engines - CFM56 Series
AD/CFM56/20 Rotating Engine Components - Additional
Inspection
9/2002
Applicability: CFM International (CFMI) CFM56 Series engines as listed in the requirement document.
Requirement: Amend the Airworthiness Limitations Sections of the Engine Shop Manuals to include the mandatory inspections per the FAA AD 2002-13-03.
Note: FAA AD 2002-13-03, Amdt 39-12790 refers which supersedes FAA AD 2000- 12-01. This Directive supersedes AD/CFM56/17.
Compliance: Within 30 days after the effective date of this AD.
This Airworthiness Directive becomes effective on 5 September 2002.
Background: This directive is prompted by an FAA study of in-service events involving uncontained failures of critical rotating parts. The actions specified by this AD are intended to prevent critical life- limited rotating engine part failure, which could result in an uncontained engine failure and damage to the aeroplane.

Overview
The Civil Aviation Regulations 1998, amended through the legislative instrument F2006B08524, address safety concerns specifically relating to aircraft engine components. Enacted by the Parliament of the Commonwealth of Australia, this legislation aims to ensure the airworthiness of aircraft and aeronautical products, specifically targeting unsafe conditions that could lead to catastrophic failures. This Airworthiness Directive was issued by the Civil Aviation Safety Authority (CASA) to rectify the identified issue of uncontained failures of critical rotating parts in CFM International (CFMI) CFM56 Series engines. The directive requires mandatory inspections to be added to the Engine Shop Manuals, aligning with FAA AD 2002-13-03 to prevent such failures and ensure the safety of the aircraft and its occupants. The policy objective behind this directive is to mitigate the risk of uncontained engine failures that could potentially damage the aeroplane and endanger lives.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 106, establishes the scope and application of the Airworthiness Directive (AD) issued by the Civil Aviation Safety Authority (CASA) delegate. This particular AD, AD/CFM56/20, pertains to CFM International (CFMI) CFM56 Series engines, which are subject to mandatory inspections in order to prevent critical life-limited rotating part failures that could lead to uncontained engine failure and subsequent damage to the aircraft. The AD applies to the specified engines as outlined in the requirement document and necessitates amendments to the Airworthiness Limitations Sections of the Engine Shop Manuals, aligning them with the FAA AD 2002-13-03. The compliance period for the implementation of this directive is within 30 days of its effective date, which is 5 September 2002. This AD is published in the Commonwealth of Australia Gazette on 14 August 2002 and serves to address safety concerns identified by an FAA study on in-service events involving uncontained failures of critical rotating parts.
Key Provisions
The Civil Aviation Regulations 1998, Part 39, specifically section 106, includes the Airworthiness Directives issued under the authority of the Civil Aviation Safety Authority (CASA). One such directive is AD/CFM56/20, issued on 26 July 2002, which pertains to the CFM International (CFMI) CFM56 Series engines. This directive mandates the amendment of the Airworthiness Limitations Sections in the Engine Shop Manuals to incorporate mandatory inspections as per the Federal Aviation Administration (FAA) AD 2002-13-03 (section 39.1(1)). This directive replaces the previous AD/CFM56/17 and became effective on 5 September 2002.
The obligations imposed by AD/CFM56/20 include the necessity for entities operating CFM56 Series engines to amend their Engine Shop Manuals within 30 days of the directive’s effective date. The primary requirement is to integrate the inspection procedures outlined in the FAA AD 2002-13-03, which were necessitated by an FAA study identifying in-service events involving uncontained failures of critical rotating parts. These inspections are critical to prevent potential uncontained engine failures that could damage the aeroplane.
Failure to comply with the requirements set forth in AD/CFM56/20 can result in serious consequences. The directive aims to ensure the airworthiness of the CFM56 Series engines by mandating specific maintenance actions. While the regulations do not explicitly state civil or criminal penalties for non-compliance, the overarching framework of the Civil Aviation Regulations 1998 provides for potential enforcement actions, including fines and other administrative penalties, which could be imposed for violations of airworthiness directives. The directive’s intent is to mitigate the risk of unsafe conditions that could lead to accidents or incidents, thereby ensuring the safety of air travel.
