Overview
The Civil Aviation Regulations 1998, enacted by the Australian Parliament, address the need for stringent safety standards within the civil aviation industry, ensuring that aircraft and related equipment meet high safety benchmarks to protect passengers and crew. Part 39, specifically Schedule of Airworthiness Directives, deals with the mandatory directives that must be followed to maintain the airworthiness of aircraft engines, such as the General Electric Turbine Engines - CF700 Series. The policy objective of these regulations is to mitigate risks associated with engine failures by enforcing specific maintenance and replacement procedures, as outlined in the Airworthiness Directives. This particular directive, AD/CF700/14, mandates the inspection and, if necessary, the replacement of certain compressor discs in the CF700-2C, -2D, -2D-2 engines, ensuring they conform to safety standards and operational requirements.
Scope and Application
The Civil Aviation Regulations 1998, specifically PART 39 - 106 pertaining to the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, apply to the specified General Electric Turbine Engines - CF700 Series, namely the CF700-2C, -2D, and -2D-2 engines equipped with particular compressor discs. These directives mandate the replacement or inspection of specific compressor discs in order to ensure airworthiness and safety in aviation operations. The regulations apply to all operators of aircraft utilising the affected engines and require compliance within a stipulated timeframe following the date of the directive. The geographic reach of these regulations is national, as they are administered by the Commonwealth of Australia through the Civil Aviation Safety Authority. Notably, the directives exclude any other components or models not specifically mentioned and rely on subordinate instruments to extend or restrict their application as necessary.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39, Section 106, contains an Airworthiness Directive (AD) issued by the Civil Aviation Safety Authority (CASA) concerning General Electric Turbine Engines of the CF700 Series (AD/CF700/14). This AD pertains to the compressor discs of certain CF700-2C and -2D engines, focusing on their removal and replacement under specific conditions. The directive applies to engines with compressor discs identified by particular serial numbers, as listed in the document (Section 1).
Section 1 of the AD mandates the removal from service of specific sixth and seventh stage compressor discs, identified by part numbers 37D401316P101 and 37D401317P101 respectively, and serial numbers provided. These discs must be replaced with serviceable ones. Additionally, it requires the inspection of first stage compressor discs, identified by part numbers 37E501428P102 and 37E50142SP106, and serial numbers listed, for material properties. This inspection must adhere to specified General Electric Company engine alert service bulletins or later approved revisions. Discs found to be satisfactory can be returned to service, while those deemed unsatisfactory must be replaced. Furthermore, removed discs are to be sent to the General Electric Company for evaluation.
Operators and owners of the affected aircraft must ensure compliance with the AD. This includes removing and replacing the specified compressor discs within ten flights after the AD's effective date of 17 March 1978. Ensuring compliance with these requirements is crucial for maintaining the airworthiness of the aircraft and the safety of all individuals on board. Failure to comply with the AD can lead to significant safety risks, potentially resulting in severe consequences, including accidents or incidents that could be attributed to non-compliance.
The AD does not explicitly state the penalties or consequences for non-compliance. However, under the Civil Aviation Act 1988 and associated regulations, failure to comply with an AD can result in enforcement actions by CASA. This may include administrative penalties, fines, and, in severe cases, criminal charges. The exact penalties can vary based on the nature and severity of the non-compliance, but they are intended to ensure that all operators and owners adhere to the safety directives issued by CASA to maintain the highest standards of aviation safety.
