The above AD is notified in the Commonwealth of Australia Gazette on 26 March 2003.
Overview
The Civil Aviation Safety Regulations 1998 (CAR 1998) were enacted to ensure the safety and airworthiness of civil aviation in Australia. As a legislative instrument of the Civil Aviation Safety Authority (CASA), this regulation plays a critical role in maintaining and enhancing aviation safety standards across the country. The Airworthiness Directive (AD) for General Electric Turbine Engines, specifically for the CF6 Series LPT Shroud Replacement, was introduced to address safety concerns identified in the affected engines. This AD, issued under subregulation 39.1 (1) of CAR 1998, mandates specific actions to be taken to correct identified unsafe conditions. The directive was issued on 4 March 2003 by James Coyne, a delegate of CASA, and became effective on 17 April 2003. The policy objective of this AD is to improve the Low Pressure Turbine containment capability of the affected engines, thereby enhancing overall aviation safety.
Scope and Application
The Civil Aviation Safety Regulations 1998, specifically Part 39 - 106, governs the issuance of Airworthiness Directives (ADs) within the Australian regulatory framework. This legislation applies to the maintenance and operation of aircraft and aeronautical products, ensuring compliance with safety standards set by the Civil Aviation Safety Authority (CASA). The AD in question pertains to General Electric CF6-50 and CF6-80C2 engines, demanding specific maintenance actions to address safety concerns identified in the Low Pressure Turbine (LPT) shroud. The directive mandates adherence to the Federal Aviation Administration (FAA) AD 2003-02-07, Amendment 39-13024, and stipulates that the required actions must be completed by a specified date. The AD is effective from 17 April 2003, and it is communicated through the Commonwealth of Australia Gazette, ensuring its reach and applicability across the nation. This regulatory instrument is pivotal for maintaining the airworthiness of specified engines, thereby enhancing overall aviation safety.
Key Provisions
The Civil Aviation Safety Regulations 1998, Part 39, specifically Section 106, establishes the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, which includes AD/CF6/51 concerning the General Electric Turbine Engines - CF6 Series LPT Shroud Replacement. This Airworthiness Directive (AD) is issued under subregulation 39.1 (1) of the Civil Aviation Regulations 1998. The AD applies to General Electric CF6-50 and CF6-80C2 engines and mandates specific action to rectify an identified unsafe condition. This action must be carried out according to the instructions detailed in the requirement section and within the specified timeframe mentioned in the compliance section. The directive aims to improve the Low Pressure Turbine containment capability of the affected engines.
The AD imposes specific obligations on the parties or entities it governs. For the CF6-50 and CF6-80C2 engines, the directive mandates that the action outlined in FAA AD 2003-02-07, Amendment 39-13024, be implemented. This includes replacing the Low Pressure Turbine (LPT) shroud to enhance the engine's containment capabilities. The compliance instructions provided in the requirement document must be followed meticulously, and adherence to the revised effective date specified in the directive is mandatory. This requirement ensures that the necessary safety improvements are uniformly applied to all affected aircraft.
The AD further outlines potential consequences for non-compliance. Failure to adhere to the Airworthiness Directive can lead to significant safety risks, potentially resulting in serious aviation incidents or accidents. While specific penalties are not explicitly stated in the AD itself, non-compliance with CASA directives generally carries severe implications. This could include enforcement actions by CASA, which might involve fines, operational restrictions, or other regulatory penalties. The gravity of these consequences underscores the importance of timely and accurate compliance with the AD to ensure the continued safety of air travel.
