AD/DHE/27 - Fuel Control Unit - Boost Capsule - Replacement

Overview

The Civil Aviation Regulations 1998 (Cth), specifically under Part 39 - 106, was enacted by the Australian Government to ensure the safety and compliance of civil aviation operations within the country. The regulation was introduced to address safety concerns related to aircraft components, particularly the need for the regular inspection and maintenance of critical engine parts. The Civil Aviation Safety Authority (CASA) is the body responsible for enforcing these regulations, with a clear policy objective to mitigate risks associated with aviation safety, thereby protecting the public and ensuring the reliability of air travel. This legislative instrument, F2006B09277, focuses on De Havilland Piston Engines, particularly mandating the replacement of the fuel control unit boost capsule in Gipsy Queen Series 70 engines. This directive is essential to prevent potential failures that could lead to a loss of engine power, thereby enhancing overall flight safety. The regulation references the "Hants and Sussex: Gipsy Modification 3014 Issue 2" document for compliance, ensuring that operators adhere to the specified modifications to maintain airworthiness standards.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 106, mandates compliance with the Airworthiness Directives issued by the Civil Aviation Safety Authority (CASA). This legislative instrument applies to all Gipsy Queen Series 70 piston engines, ensuring the safety and airworthiness of aircraft utilising these engines. The directive requires the replacement of the fuel control unit's boost capsule to prevent failures that could result in a loss of engine power, thereby maintaining the safety standards stipulated by CASA. The geographic reach of this legislation is national, applying across all states and territories of Australia, as it falls under the Commonwealth's jurisdiction. There are no specific exclusions or exemptions mentioned in the directive; however, compliance must be demonstrated in accordance with the requirement document, which is referenced as Hants and Sussex: Gipsy Modification 3014 Issue 2. The application of this directive may be further extended or clarified through subordinate instruments issued by CASA.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39, Section 106, contain the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives, including AD/DHE/27 concerning De Havilland Piston Engines. This directive mandates the replacement of the fuel control unit's boost capsule for all Gipsy Queen Series 70 engines to prevent potential failures that could result in loss of engine power. The compliance requirement is detailed in Hants and Sussex's Gipsy Modification 3014 Issue 2, which must be adhered to for this directive to be considered complete. Under this directive, the operators and owners of Gipsy Queen Series 70 engines must ensure that the fuel control unit's boost capsule is replaced as specified. This requirement is intended to maintain the airworthiness of the engines, ensuring safety in aviation operations. The directive provides specific guidelines and references a compliance document to ensure that the modifications are carried out correctly and consistently. The obligation lies on the operators and owners to follow these guidelines meticulously and to verify that the modifications are implemented as per the standards outlined. Failure to comply with AD/DHE/27 can lead to serious consequences. The Civil Aviation Regulations 1998 impose penalties for non-compliance with airworthiness directives. In this case, operators and owners who do not adhere to the specified requirements may face enforcement actions. The potential penalties include fines and other sanctions as prescribed by the regulations. The exact penalties are determined by the severity of the breach and the impact on aviation safety but can be substantial, highlighting the importance of strict adherence to the directive.
