AD/AL 250/64 Amdt 3 - Internal Energy Absorbing Ring

Overview

The Civil Aviation Regulations 1998, specifically under Part 39 - 106, addresses safety standards for civil aviation, ensuring the airworthiness of aircraft and related components. One such regulation, AD/AL 250/64 Amendment 3, pertains to the installation of an internal energy absorbing ring in Allison model 250-C30 series engines, as outlined in Allison CEB-A-72-3128 R1, Paragraph 2 Accomplishment Instructions. This amendment was enacted to enhance safety measures and update previous directives by incorporating a more comprehensive approach to engine safety, removing outdated references to external containment shields and the Allison Assured Engine configuration. The policy objective behind this amendment is to rationalise the requirements and expand the applicability to all C30 series engines, thereby improving the overall safety and compliance of the aviation fleet. The Civil Aviation (Safety) Regulations 1998 were established by the Commonwealth of Australia and are administered by the Civil Aviation Safety Authority (CASA), which is tasked with ensuring compliance and safety within the aviation industry. This legislative instrument aims to address gaps in engine safety protocols by mandating the installation of specified components, such as the internal energy absorbing ring, to mitigate risks associated with engine failures. The regulation is designed to ensure that all relevant aircraft and engines meet stringent safety standards, thereby protecting passengers, crew, and the public from potential hazards.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 106, pertains to the Civil Aviation Safety Authority's schedule of airworthiness directives, focusing on Allison Turbine Engines - 250 Series. This legislation applies to all Allison model 250-C30, C30L, C30M, C30P, and C30S engines installed in aircraft within the Commonwealth of Australia. The directive mandates the installation of an internal energy absorbing ring in accordance with specific guidelines outlined in Allison CEB-A-72-3128 R1, Para 2 Accomplishment Instructions, and should be implemented in conjunction with CAO 106 AD/AL 250/66 Amdt 2. The requirement is intended to enhance safety by mitigating potential risks associated with engine failures. Compliance is to be strictly adhered to as specified in the detailed requirement documents, with particular attention to the amendments that rationalize previous requirements and expand the scope of applicable engines and aircraft. The directive's applicability extends across the Commonwealth, ensuring that all relevant operators and maintenance personnel within Australia comply with the stipulated safety measures.

Key Provisions

The key provision in the Civil Aviation Regulations 1998, specifically in Part 39 - 106, mandates the installation of an internal energy absorbing ring for Allison model 250-C30, C30L, C30M, C30P, and C30S engines. This is outlined in AD/AL 250/64 Amendment 3, which requires compliance with Allison CEB-A-72-3128 R1, Paragraph 2 Accomplishment Instructions. This directive should be executed alongside CAO 106 AD/AL 250/66 Amendment 2 and references FAA AD 86-19-12. Compliance must be achieved as detailed in the requirement document. The obligations imposed by this regulation are clear and straightforward. Operators and owners of the specified Allison engines must install the internal energy absorbing ring as per the referenced instructions. This installation is necessary to ensure the safety and airworthiness of the engines in question. The directive provides a specific set of instructions from Allison, which must be followed meticulously to meet regulatory standards. Failure to comply with these obligations could result in significant safety risks and potential non-compliance with civil aviation safety regulations. Breach of the requirements set forth in the Civil Aviation Regulations 1998 could lead to serious consequences. Although the specific penalties are not detailed within the provided text, it is well-established within Australian civil aviation law that non-compliance with airworthiness directives can result in severe penalties. These may include fines, enforcement actions, or even grounding of the affected aircraft until the necessary compliance measures are taken. The severity of the penalties underscores the importance of adhering to these directives to maintain the highest standards of safety in civil aviation.
