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.
General Electric Turbine Engines - CF6 Series
AD/CF6/49 High Pressure Compressor 3-9 Spool - Inspection 3/2003
Applicability: General Electric CF6-45/50/80A/80C2/80E1 series engines as identified in FAA AD 2002-25-08.
Requirement: Carry out the initial inspection and repetitive inspections per the requirements of FAA AD 2002-25-08.
Note: FAA AD 2002-25-08 Amdt 39-12984 refers. This Directive supersedes AD/CF6/41 Amdt 1 (FAA AD 99-24-15) and AD/CF6/43 Amdt 1 (FAA AD 2000-16-
12).
Compliance: As detailed in the Requirement document with a revised effective date of this Directive.
This Airworthiness Directive becomes effective on 20 March 2003.
Background: This Directive harmonises the additional inspection requirements contained in two earlier Directives. These additional inspections, derived from service experience, help to prevent uncontained engine failures.

Overview
The Civil Aviation Regulations 1998 (CAR 1998) were enacted to regulate civil aviation operations in Australia, ensuring that aircraft and aeronautical products meet specific safety standards. Part 39 of the CAR 1998 includes provisions for Airworthiness Directives, which are issued by the Civil Aviation Safety Authority (CASA) to address identified safety issues. The Airworthiness Directive for General Electric Turbine Engines - CF6 Series AD/CF6/49, issued on 20 March 2003, is an example of such measures. This directive was introduced to address the risk of uncontained engine failures, harmonising previous inspection requirements to enhance safety. CASA, as the delegate, mandates these inspections in line with FAA AD 2002-25-08, aiming to mitigate the identified unsafe conditions through regular monitoring and maintenance actions.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 106, applies to the maintenance and operation of aircraft and aeronautical products within Australia. This particular Airworthiness Directive (AD) targets General Electric CF6 series engines, specifically models CF6-45/50/80A/80C2/80E1, and mandates inspections to prevent uncontained engine failures. The AD is issued by a delegate of the Civil Aviation Safety Authority (CASA) and aligns with the Federal Aviation Administration’s (FAA) AD 2002-25-08. The requirement for inspections is intended to ensure compliance with safety standards, addressing issues identified through service experience. This AD supersedes previous directives, consolidating inspection requirements into a single directive for clarity and efficiency. The AD applies to any aircraft utilising the specified engines and must be adhered to by aircraft operators and maintenance providers within the Australian jurisdiction. The directive is effective from 20 March 2003, as gazetted on 26 February 2003.
Key Provisions
The Civil Aviation Regulations 1998, under PART 39, mandate the issuance of Airworthiness Directives (AD) by the Civil Aviation Safety Authority (CASA) delegate to ensure the safety of civil aviation. Section 39.1(1) of the CAR 1998 provides the authority for the CASA delegate to issue such directives. The AD in question pertains to the General Electric CF6 series turbine engines, specifically models CF6-45/50/80A/80C2/80E1, as identified in FAA AD 2002-25-08. The directive mandates initial and repetitive inspections to prevent uncontained engine failures, as detailed in FAA AD 2002-25-08, which references FAA AD 99-24-15 and FAA AD 2000-16-12, and supersedes earlier directives AD/CF6/41 and AD/CF6/43. Compliance with the AD is required as per the specified effective date of 20 March 2003.
The obligations under this AD include conducting inspections as per the FAA AD 2002-25-08 requirements. This entails detailed inspections of the high-pressure compressor 3-9 spool to ensure it meets safety standards, thereby preventing uncontained engine failures. The directive mandates that these inspections are carried out in the circumstances and according to the instructions outlined in the requirement section of the directive. The compliance section of the AD specifies the revised effective date for the directive, ensuring that all parties subject to the AD are aware of when the compliance is required. This includes operators of the affected engines ensuring they adhere to the inspection schedule and procedures as set forth in the AD.
Failure to comply with the AD can lead to serious consequences. The AD is designed to maintain the airworthiness of the aircraft by preventing unsafe conditions that could result in catastrophic failures. Non-compliance with the AD could result in the grounding of affected aircraft, which could have severe operational, financial, and safety implications. The AD does not explicitly state civil or criminal penalties for non-compliance, but any breach of airworthiness directives can lead to regulatory action, including fines, enforcement actions, or the suspension of the aircraft's operating certificate. The seriousness of the potential consequences underscores the importance of adhering to the AD's requirements.
