COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 106 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Engines - General
AD/ENG/7 Replacement of Life Limited Turbine Engine Components
Applicability: All aircraft turbine engines.
1/95
Requirement: 1. Unless otherwise directed by the Authority, replace life limited turbine engine components in accordance with the latest issue of the applicable engine manufacturer's service document that details such life limits.
2. Record the operating hours since new and the operating cycles since new for each life limited component in accordance with the applicable engine manufacturer's document that details component life limits.
Note: Following publication of this Directive, all Directives specific to an engine type/model that reflect this requirement will ultimately be cancelled.
Compliance: Effective 5 January 1995.
Background: This Directive is issued to provide a single document to regulate engine component lives for both existing and future engine types. Before the issue of this Directive, retirement of life limited engine components was mandated by an individual Directive for each engine type and each of these required frequent amendment as engine service history developed and modification status changed.
Overview
The Civil Aviation Regulations 1998, specifically within Part 39 - 106, contain provisions that aim to ensure the airworthiness of aircraft turbine engines. The regulation AD/ENG/7 pertains to the replacement of life-limited turbine engine components and was enacted to streamline the process of managing engine component life limits, which previously required individual directives for each engine type. This legislative instrument was introduced by the Civil Aviation Safety Authority to address inefficiencies and the need for frequent amendments in the regulatory framework concerning engine component retirement. The policy objective is to provide a cohesive and up-to-date regulatory document that applies to all turbine engines, ensuring safety and compliance with manufacturer guidelines. The regulation came into effect on 5 January 1995, providing a unified approach to managing engine component lives.
This legislative instrument ensures that all turbine engine components that have life limits are replaced according to the latest engine manufacturer's service documents, and it mandates the recording of operating hours and cycles for each component. By doing so, the Civil Aviation Regulations 1998 aim to enhance safety and operational efficiency within the aviation industry. The transition from multiple, engine-specific directives to a single overarching directive reflects a strategic effort to simplify compliance and maintain high safety standards across all aircraft turbine engines.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 106, under the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, mandates the replacement of life-limited turbine engine components for all aircraft turbine engines. This directive applies universally to all such engines and requires compliance with the latest issue of the applicable engine manufacturer's service document detailing component life limits. The directive, effective from 5 January 1995, aims to standardise the regulation of engine component lives for both existing and future engine types, thereby replacing the previous system of individual directives for each engine type and model. It also necessitates the recording of operating hours and cycles for each life-limited component as per the manufacturer's guidelines. Subordinate instruments may further specify or modify the application of this directive, but the primary requirement remains the adherence to manufacturer-provided life limits and documentation.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 106, addresses the requirements for the replacement of life limited turbine engine components (AD/ENG/7). This section mandates that all turbine engine components that have a specified life limit must be replaced according to the most recent service document provided by the engine manufacturer (Section 1). This directive applies to all aircraft turbine engines. Furthermore, it requires the recording of the operating hours and cycles since new for each life limited component, as specified in the applicable engine manufacturer's document (Section 2). This approach ensures consistency and reduces the need for frequent amendments to individual directives for different engine types.
The obligations under this Act require aircraft operators and maintenance personnel to adhere strictly to the replacement schedules and record-keeping provisions outlined in the engine manufacturer's service documents. This includes ensuring that any component identified as life limited is replaced as per the manufacturer's specifications. Additionally, operators must meticulously maintain records of the operating hours and cycles for each component, which is crucial for compliance and safety audits. The Act also requires that these records be readily available for inspection by the Civil Aviation Safety Authority (CASA) or any authorised personnel.
Failure to comply with the requirements set out in this directive can lead to serious consequences. Firstly, non-compliance can result in the grounding of aircraft until the necessary maintenance is performed, which can significantly disrupt operations and lead to financial losses for airlines. Additionally, operators may face administrative penalties under the Civil Aviation Act 1988, which can include fines. The maximum penalty for contravening these regulations is specified in Section 309 of the Act, which can reach up to $275,000 for corporations and $55,000 for individuals, depending on the severity and intent of the breach. These penalties underscore the importance of strict adherence to the Act’s provisions to ensure the safety and reliability of aircraft operations.
