Overview
The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, address the need for stringent safety regulations in the aviation industry to ensure the safety of air travel. Part 39, specifically pertaining to airworthiness directives, aims to maintain the highest safety standards for aircraft and their components. One such directive, AD/AL 250/13, introduced to enhance the safety of Allison Turbine Engines - 250 Series, mandates the installation of improved indicating magnetic drain plugs. This directive was introduced to address the problem of inadequate monitoring and maintenance of engine oil levels, which could lead to engine failure. The policy objective is to ensure the reliability and safety of aircraft engines through regular and effective maintenance practices.
This legislative instrument, F2006B02236, specifies the applicability of the directive to certain Allison 250-C18 and 250-C18A series engines, with compliance required within 100 hours’ time in service after 30 October 1970. By implementing this directive, the Civil Aviation Safety Authority aims to mitigate risks associated with engine failure due to inadequate oil levels, thereby safeguarding the aviation industry and the public.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 106, applies to all 250-C18 and 250-C18A series Allison turbine engines with particular serial numbers, as detailed in AD/AL 250/13. This legislation mandates the installation of improved indicating magnetic drain plugs on the specified engines to enhance safety and operational standards within the aviation industry. The requirement necessitates compliance within 100 hours of time in service after the directive's introduction on 30 October 1970, as outlined in Allison 250 CEB No. 109. The Act's jurisdictional reach is national, applying across the Commonwealth of Australia, and is enforced by the Civil Aviation Safety Authority (CASA). The regulation does not specify exclusions or exemptions, thus it applies broadly to the entities and industries operating within its defined scope. The application of the Act may be further detailed or extended through subordinate instruments, which may provide additional guidelines or clarifications for compliance.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39, Section 106, contain the Schedule of Airworthiness Directives, which is crucial for ensuring the safety and airworthiness of aircraft. Section AD/AL 250/13 pertains to Allison Turbine Engines of the 250 Series. This section mandates the introduction of improved indicating magnetic drain plugs for specific serial numbers of the 250-C18 and 250-C18A engines. These serial numbers include ranges such as 800001 to 800165, CAE 800266 to 801575, CAE 800166 to 800265, 801600 to 801799, and 801900 to 801950. The directive refers to Allison 250 CEB No. 109, which provides the necessary technical details and compliance requirements.
Operators and owners of aircraft equipped with the specified Allison Turbine Engines are required to comply with this directive. The compliance must occur within 100 hours of time in service after 30 October 1970, which means that within this timeframe, the improved indicating magnetic drain plugs must be installed on the affected engines. This requirement ensures that the engines maintain their airworthiness and safety standards, preventing potential issues that could arise from inadequate drain plug functionality.
Failure to comply with the Airworthiness Directive AD/AL 250/13 could lead to significant consequences. The Civil Aviation Safety Authority (CASA) has the authority to enforce this directive, and non-compliance can result in the grounding of the aircraft until the necessary modifications are made. Additionally, operators and owners may face financial penalties, enforcement actions, or other regulatory sanctions imposed by CASA. The specific penalties for non-compliance can vary, but they are designed to ensure that all affected aircraft meet the required safety standards without delay.
