AD/DHE/3 - Propeller Oil Transfer System - Modification

Overview

The Civil Aviation Regulations 1998, amended by the legislative instrument F2006B09278, were enacted to ensure the safety and uniformity of aviation practices in Australia. This particular regulation, included in Part 39 - 106 of the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, addresses a specific issue related to the propeller oil transfer system of Gipsy Queen 70 series De Havilland Piston Engines. The regulation was introduced to ensure that any modifications to this system meet safety standards before installation in aircraft. The objective of this directive, as outlined in the document, is to mandate compliance with either the specified DH Modifications (G1331, G1493, and G1728) or the Aeronautical Notice (ANO) 106.1.7.6.5.2, thereby enhancing the reliability and safety of these aircraft components. This legislative instrument was enacted by the Australian Government to maintain high safety standards within the nation's aviation industry.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 106, applies to Gipsy Queen 70 series piston engines in relation to propeller oil transfer system modifications. This regulation mandates that any aircraft utilising these engines must adhere to the directives outlined in either DH Mods G1331, G1493, and G1728 or ANO 106.1.7.6.5.2 prior to installation in an aircraft. This regulation is applicable across the Commonwealth of Australia, thereby affecting all operators, manufacturers, and maintenance providers within the nation's civil aviation sector. The scope of the regulation ensures that these specific modifications are uniformly implemented to maintain safety and operational standards across the industry. There are no stated exclusions or exemptions within the text, thus all applicable engines must comply with the specified modifications. The application of these regulations may be extended or further defined through subordinate instruments issued by the Civil Aviation Safety Authority.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 106, addresses the airworthiness directives concerning the propeller oil transfer system modification for De Havilland Piston Engines of the Gipsy Queen 70 series. The key operative sections of this legislation, particularly AD/DHE/3, mandate modifications to the propeller oil transfer system. According to section (1), the modifications must be in line with either DH Mods G1331, G1493, and G1728 or ANO 106.1.7.6.5.2, which are outlined in the relevant documents. Compliance with these modifications is a critical requirement before the engines can be installed in an aircraft, as stated in section (2). The legislation imposes clear obligations on the parties or entities it governs. Owners and operators of aircraft equipped with Gipsy Queen 70 series engines must ensure that the propeller oil transfer system is modified in accordance with the specified directives. This obligation extends to any person who intends to install these engines in aircraft, demanding that the necessary modifications be completed prior to installation. These requirements are explicitly stated in section (1) and (2), ensuring there is no ambiguity regarding compliance. Failure to adhere to these airworthiness directives can result in serious consequences. Under the Civil Aviation Regulations 1998, non-compliance with these provisions is considered an offence. The penalties for breaching these regulations can include both civil and criminal consequences. Specifically, section (3) of the Act outlines that violations may lead to enforcement actions by the Civil Aviation Safety Authority, which can impose fines or other sanctions. The maximum penalties for such offences are detailed in the broader regulatory framework, but they underscore the importance of strict adherence to the directives to maintain airworthiness standards.
