AD/AL 250/52 Amdt 1 - Engine Fuel and Control - Bendix Fuel Control Assemblies and Power Turbine Governor Assemblies

Overview

The Civil Aviation Regulations 1998, enacted by the Commonwealth of Australia, form a comprehensive framework for the regulation of civil aviation within Australia. Among these regulations, Part 39 focuses on airworthiness directives, with specific attention to ensuring the safety and reliability of various aircraft components. The regulation at hand, AD/AL 250/52 Amendment 1, pertains specifically to Allison 250 Series turbine engines, addressing issues related to fuel and control assemblies, and the power turbine governor assemblies. This legislative instrument was introduced to address the need for stringent safety measures in the operation of these engines, ensuring compliance with international standards as set forth by the Federal Aviation Administration (FAA). The objective is to maintain the highest standards of airworthiness, thereby protecting the safety of passengers and crew. The Civil Aviation Safety Authority is the enacting body responsible for enforcing these regulations.

Scope and Application

The Civil Aviation Regulations 1998, under Part 39, specifically within the Civil Aviation Safety Authority Schedule of Airworthiness Directives, governs the airworthiness of aircraft engines, including the Allison 250 Series. The regulation applies directly to the specified Allison 250 series engines, ensuring compliance with the airworthiness directives to maintain safety standards. The legislation applies nationally across Australia, as it falls under the Commonwealth’s regulatory framework, thereby affecting all entities and persons involved in the operation and maintenance of these engines within the country. The directive encompasses various models of the Allison 250 series engines, explicitly listed in the document, and mandates adherence to the specified requirements documents to ensure safety. Notably, the regulation does not include any exclusions or exemptions, and its application is reinforced by reference to the Federal Aviation Administration’s AD 82-24-05 Amendment 39-4498, indicating a cross-jurisdictional alignment with international safety standards.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39, contain the Schedule of Airworthiness Directives, with AD/AL 250/52 Amendment 1 (AD/AL 250/52 Amdt 1) being one of the directives. This directive pertains to the Allison 250 Series engines, particularly the engine fuel and control assemblies, including the Bendix Fuel Control Assemblies and the Power Turbine Governor Assemblies (Section 1/83). The directive applies to various Allison 250 series engine models, including the Allison 250-C18, C20, B15G, B17, C28B, C28C, C30, C30P, and C30S, each referenced with their respective documents and notes. The primary requirement of AD/AL 250/52 Amdt 1 is that the specified Allison 250 Series engines must comply with the applicable requirement documents, ensuring that the engine fuel and control assemblies meet the necessary safety standards. This includes adhering to the FAA AD 82-24-05 Amendment 39-4498, which is incorporated into the AD document reference to ensure consistency and compliance with federal aviation regulations. Entities and parties governed by this directive must ensure that their Allison 250 Series engines are inspected, maintained, and, if necessary, repaired or replaced according to the detailed specifications provided in the referenced documents. This involves rigorous checks on the fuel control assemblies and power turbine governor assemblies to ensure they operate within the safety parameters set forth by the Civil Aviation Safety Authority (CASA). It is crucial that operators and maintenance personnel are fully aware of and adhere to these requirements to prevent any potential safety issues. Failure to comply with the provisions of AD/AL 250/52 Amdt 1 can result in severe consequences. The Civil Aviation Regulations 1998 impose strict penalties for non-compliance, which may include both civil and criminal liabilities. Civil penalties can be substantial, and criminal penalties may apply, particularly if the non-compliance leads to safety incidents or accidents. The exact penalties depend on the severity and impact of the breach but can include fines and, in some cases, imprisonment for individuals found responsible for the non-compliance.
