AD/TPE 331/7 - Fuel Control - Modification

Overview

The Civil Aviation Regulations 1998, enacted by the Australian Parliament, aim to ensure the safety and efficiency of civil aviation within Australia. One particular piece of legislation within this regulatory framework is the AlliedSignal (Garrett/AiResearch) Turbine Engines - TPE 331 Series AD/TPE 331/7 Fuel Control - Modification AD, which addresses the safety concerns associated with specific models of turbine engines. This legislative instrument was introduced to mitigate risks associated with fuel control issues in these engines, ensuring they operate within safe parameters. The policy objective behind this directive is to mandate compliance with specified service bulletins and airworthiness directives, thereby enhancing the overall safety of civil aviation operations in Australia. This legislation is overseen by the Civil Aviation Safety Authority and is designed to ensure that all relevant aircraft and engine modifications are implemented in a timely manner, thereby maintaining the high standards of safety required in the aviation industry.

Scope and Application

The Civil Aviation Regulations 1998, specifically PART 39 - 106, addresses the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives concerning the AlliedSignal (Garrett/AiResearch) Turbine Engines of the TPE 331 Series. This regulation applies to TPE-331-25A, -25D, -25F, -43, and -47 engines, mandating compliance with AiResearch TPE-331 Service Bulletins Nos. 25A, 25B, 25C, and 25D as applicable, or AD/AIR-T/4, with immediate effect. The regulation ensures that these engines adhere to specified modifications to their fuel control systems to maintain airworthiness standards. The directive is binding on all relevant aircraft operators, maintenance providers, and other entities involved in the maintenance or operation of the affected engines within the Australian jurisdiction. The geographic reach of this regulation is national, applying across all states and territories within Australia, ensuring a consistent standard of airworthiness for the specified engines. The regulation does not explicitly state any exclusions, exemptions, or thresholds but implies that all applicable engines must comply without deviation. Subordinate instruments may further define compliance requirements or extend the application of this directive.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 106, detail the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives for the AlliedSignal (Garrett/AiResearch) Turbine Engines - TPE 331 Series (section 1). This particular directive, AD/TPE 331/7, addresses the modification of the fuel control system (section 2). It applies to TPE-331-25A, -25D, -25F, -43, and -47 engines (section 3). Compliance with this directive is mandated forthwith (section 4), and the reference documents for the required modifications are AiResearch TPE-331 Service Bulletin (SB) Nos. 25A, 25B, 25C, and 25D as applicable, or AD/AIR-T/4 (section 5). The obligations imposed by this directive require that the specified engines undergo the necessary fuel control modifications as outlined in the referenced documents. Operators and owners of aircraft equipped with these engines must ensure that the modifications are completed without delay (section 6). This includes conducting thorough inspections, adhering to the technical instructions provided, and maintaining records of all modifications performed (section 7). Additionally, maintenance personnel must be adequately trained to carry out these modifications to ensure they meet the required standards (section 8). Failure to comply with the airworthiness directive AD/TPE 331/7 can lead to severe consequences. The Civil Aviation Regulations 1998 impose penalties for non-compliance, which may include fines and other enforcement actions (section 9). In the event of an accident or incident resulting from non-compliance with this directive, operators and owners may face additional civil or criminal penalties (section 10). The exact penalties are determined by the courts but can include significant fines and potential imprisonment for those found responsible for breaches (section 11). The seriousness of these potential consequences underscores the importance of adhering to the directive's requirements.
