AD/CF6/22 - Fuel Manifold Inspection and Replacement

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, provide a comprehensive framework for the regulation of civil aviation within the country, addressing various safety and operational standards. Part 39 of these regulations, specifically Schedule of Airworthiness Directives, is concerned with ensuring that aircraft and their components meet the necessary safety standards. One such directive, AD/CF6/22, pertains to General Electric Turbine Engines of the CF6 Series, focusing on the inspection and replacement of fuel manifolds for the CF6-80 C2 Series Engines. This directive was introduced to address the safety issue of potential fuel leaks, which could lead to severe consequences such as engine fires. The requirement to inspect and replace fuel manifolds in accordance with the Federal Aviation Administration's (FAA) AD 91-20-02 was prompted by a reported failure of a fuel manifold weld joint, underscoring the need for stringent safety measures in civil aviation. The policy objective behind AD/CF6/22 is to ensure the continued airworthiness of aircraft equipped with CF6-80 C2 Series Engines by mandating regular inspections and necessary replacements of fuel manifolds to prevent failures and ensure operational safety. The directive references relevant FAA service bulletins to provide technical guidance and compliance requirements, with an effective date set for 17 September 1992, ensuring that all stakeholders are aware of the mandatory actions required to maintain safety standards in civil aviation.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 106, applies to the Civil Aviation Safety Authority’s schedule of airworthiness directives, including AD/CF6/22 concerning General Electric Turbine Engines of the CF6 series. This legislation mandates that the requirement to inspect and replace fuel manifolds in accordance with FAA AD 91-20-02 applies to CF6-80 C2 Series Engines. The directive is intended to address the technical requirements for maintaining airworthiness by preventing potential fuel leaks that could lead to engine fires. The regulation's applicability extends to any entity or individual operating aircraft equipped with the specified engines within the jurisdiction of the Commonwealth of Australia. Compliance with this directive is mandatory and must adhere to the specified effective date of 17 September 1992, as outlined in the Requirement Document. Subordinate instruments may further detail the procedures and technical requirements for the inspection and replacement of fuel manifolds, ensuring that all operations align with the highest safety standards set forth by the Civil Aviation Safety Authority.

Key Provisions

The Civil Aviation Regulations 1998, Part 39 - 106, as amended, includes a Schedule of Airworthiness Directives, specifically AD/CF6/22, which pertains to the inspection and replacement of fuel manifolds in General Electric CF6 Series Engines (Section 106). This directive applies to CF6-80 C2 Series Engines and mandates that inspections and replacements must be carried out in accordance with the technical requirements outlined in FAA AD 91-20-02 (Section 106). The directive references relevant service bulletins, GE SB 73-115 Revision 1 and GE SB 73-114 Revision 2, to ensure compliance with the specific technical standards and procedures. The obligations imposed by AD/CF6/22 include the requirement for authorised personnel to inspect the fuel manifolds of the specified engine series for any signs of wear, damage, or potential failure points. If any issues are identified during the inspection, the fuel manifolds must be replaced as per the directive's technical requirements. This involves not only the physical replacement of parts but also adherence to the specific maintenance procedures and documentation protocols outlined in the FAA AD 91-20-02 and the referenced General Electric service bulletins. Compliance with these directives is essential to ensure the continued airworthiness of the aircraft using these engines. Failure to comply with AD/CF6/22 can result in serious safety hazards, including the potential for engine fires due to fuel leaks. The potential consequences of non-compliance are severe, as they can directly impact the safety of air travel. The regulations do not explicitly outline specific penalties for breaches of these directives within the Civil Aviation Regulations 1998, but non-compliance with airworthiness directives can lead to enforcement actions by the Civil Aviation Safety Authority (CASA). Such actions may include fines, enforcement notices, and potentially grounding of the aircraft until the required maintenance is carried out. The severity of the penalties and consequences will depend on the nature and extent of the non-compliance, as well as any resultant safety risks identified.
