Overview
The Civil Aviation Regulations 1998, specifically Part 39 - 106, pertains to the safety directives for ensuring airworthiness, as overseen by the Civil Aviation Safety Authority. Enacted in 1988, this legislation was introduced to address the need for stringent regulatory oversight in maintaining the safety and airworthiness of aircraft in Australia. The regulations are overseen by the Parliament of Australia, with a policy objective to protect the public and ensure the safety of civil aviation by setting and enforcing stringent standards for airworthiness directives. This legislative instrument, F2006B11182, targets a specific issue by mandating the evaluation and, where necessary, the replacement of power turbine governors in certain turbine engines to prevent potential safety hazards.
The directive AD/LTS/3 under the Civil Aviation Regulations 1998 specifically addresses the issue of ensuring the functional integrity of power turbine governors in the AlliedSignal (Lycoming) LTS 101 Series engines. The directive applies to all LTS 101-750C-1 engines equipped with specific power turbine governors and mandates either a functional evaluation check or a replacement in compliance with detailed procedures set forth by Lycoming Service Bulletin No. LTS101C-73-20-0058 Rev. 1. This regulation ensures that such checks are conducted either within a specified timeframe after a particular date or prior to the issuance of an Australian Certificate of Airworthiness, thereby enhancing the overall safety standards of civil aviation operations in Australia.
Scope and Application
The Civil Aviation Safety Authority's regulation applies specifically to LTS 101-750C-1 engines with serial numbers listed in the Requirement Document and equipped with power turbine governors bearing parts numbers 4-302-024-02 or -02A. This requirement is imperative for ensuring the safety and operational integrity of these engines in the Australian aviation sector. The directive necessitates a functional check of the power turbine governor in accordance with Lycoming Service Bulletin No. LTS101C-73-20-0058 Rev. 1, specifically paragraphs 2, 3, and 4, or compliance with AD/LYC-T/25. The compliance deadline is set at 100 hours of time in service after 31 May 1985, or upon the installation of the affected engine or governor, or prior to the issuance of an Australian Certificate of Airworthiness. This regulatory measure is crucial for maintaining the airworthiness of the specified engines within the national jurisdiction, ensuring adherence to stringent safety standards.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 106, under the Civil Aviation Safety Authority Schedule of Airworthiness Directives, addresses the safety of AlliedSignal (Lycoming) Turbine Engines, focusing on the LTS 101 Series. The directive AD/LTS/3 mandates a power turbine governor evaluation check or replacement for certain engines (sections 1 and 2). This directive applies to all LTS 101-750C-1 engines with specific serial numbers and fitted with power turbine governors of particular part numbers (section 3). The requirement entails performing a power turbine governor evaluation check in accordance with Lycoming Service Bulletin No. LTS101C-73-20-0058 Rev. 1, paragraphs 2, 3, and 4, or following the instructions in AD/LYC-T/25 (section 4). Compliance with this directive must be achieved within 100 hours of time in service after 31 May 1985, upon installation of the affected engine/power turbine governor, or before the issuance of an Australian Certificate of Airworthiness (section 5).
The Act imposes specific obligations on the parties or entities it governs. Operators of LTS 101-750C-1 engines must ensure that the power turbine governor evaluation check is carried out as per the specified service bulletin or the alternate directive. This check must be completed within the prescribed timeframes to maintain compliance with the Civil Aviation Regulations. If an engine or power turbine governor is installed, the evaluation check must be conducted prior to the issuance of the Australian Certificate of Airworthiness, ensuring that all safety standards are met before the engine is put into service.
Failure to comply with the requirements of this directive can lead to serious consequences. Non-compliance may result in civil or criminal penalties. While specific penalties are not detailed in the provided text, non-compliance with airworthiness directives generally can result in severe civil penalties, including fines and potential grounding of the aircraft. Additionally, non-compliance could lead to criminal charges, especially if the failure to adhere to the directive results in an aviation accident or incident. The severity of the penalties depends on the nature and extent of the non-compliance, but they can be significant, reflecting the critical importance of adhering to airworthiness directives for ensuring safety in aviation operations.
