Overview

The Civil Aviation Regulations 1998, as amended through legislative instrument F2006B09273, address the critical issue of ensuring the airworthiness of aircraft by imposing stringent requirements on engine maintenance and modifications. Enacted by the Australian Parliament, these regulations were designed to enhance aviation safety by mandating specific modifications for certain types of piston engines, particularly the Gipsy Queen 111 and 111A.6/72 engines, to maintain their airworthiness standards. The policy objective behind these regulations is to ensure that these engines meet the minimum modification standards at major reconditioning, thus preventing potential safety hazards that could arise from engine failure. This legislative instrument aims to provide clear and enforceable directives that require compliance with the modifications specified in Rolls Royce Gipsy Technical News Sheet TNS G No. 15 dated 18 February 1970, particularly those marked with an asterisk and those outlined in Appendix 4 dated 27 June 1963.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 106, outlines the scope and application of Airworthiness Directives issued by the Civil Aviation Safety Authority (CASA) to ensure the safety and airworthiness of aircraft and their components. This legislative instrument targets Gipsy Queen 111 and 111A.6/72 piston engines, mandating compliance with specific modifications to maintain airworthiness standards. The directive requires that these engines incorporate modifications detailed in Rolls Royce Gipsy Technical News Sheet TNS G No. 15 dated 18 February 1970 and Appendix 4 dated 27 June 1963, particularly those marked with an asterisk, before being installed following the next reconditioning completed after 30 June 1972. This regulation applies to all relevant entities and persons involved in the maintenance and operation of these aircraft engines within the Commonwealth of Australia, ensuring adherence to established safety protocols and standards. The directive extends its reach across the national airspace, encompassing all states and territories, and is enforced by CASA, with compliance being a mandatory requirement for the continued operation of the specified aircraft engines.

Key Provisions

The Civil Aviation Regulations 1998, specifically under Part 39 - 106, mandate that certain engines, such as the Gipsy Queen 111 and 111A.6/72, must meet specific modification standards. According to the Airworthiness Directive AD/DHE/23, these engines must incorporate modifications marked with an asterisk in Rolls Royce Gipsy Technical News Sheet TNS G No. 15 dated 18 February 1970, and Appendix 4 dated 27 June 1963. The requirement is that these modifications must be completed before installation following the next reconditioning after 30 June 1972. This ensures that the engines maintain the necessary safety standards for continued operation. Entities or parties governed by these regulations must ensure that all applicable modifications are incorporated into the engine before it is reinstalled after a major reconditioning process. This involves adhering to the technical instructions provided in the specified Rolls Royce documents. The compliance with these directives is critical for maintaining the airworthiness of the engines and ensuring that they meet the safety standards set by the Civil Aviation Safety Authority. Failure to comply with these directives can lead to severe consequences. The regulations outline specific penalties and consequences for non-compliance. While the exact penalties are not detailed in the text, it is understood that non-compliance with airworthiness directives can result in significant fines, penalties, or other legal repercussions. The enforcement of these regulations is aimed at ensuring the safety and reliability of the aircraft and its components, underscoring the importance of strict adherence to the prescribed standards.
