AD/CF700/6 - Fuel Nozzle

Overview

The Civil Aviation Regulations 1998, specifically PART 39 - 106, includes the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, which was enacted to ensure that aircraft and their components meet safety standards and regulations. This particular legislation addresses issues with the General Electric Turbine Engines of the CF700 series, particularly those involving fuel nozzles identified by specific part numbers. The directive was introduced to mitigate potential safety risks associated with these components, ensuring that they are inspected and, if necessary, modified according to specific service bulletins to maintain airworthiness and safety standards. The Civil Aviation Regulations 1998 were enacted by the Commonwealth of Australia Parliament, with the policy objective of maintaining the highest possible safety standards in civil aviation. The regulations aim to prevent accidents and incidents by ensuring that all aircraft and their components adhere to stringent safety directives. For the CF700 series engines, the directive mandates inspections and modifications to the fuel nozzles as per specified service bulletins, ensuring these engines meet the necessary safety requirements before being installed in aircraft.

Scope and Application

The Civil Aviation Regulations 1998, under PART 39 - 106, specifically addresses the applicability and compliance requirements for General Electric Turbine Engines of the CF700 series, focusing on the fuel nozzles with part numbers 37D401657P104, P107, and P109. This regulation applies to all CF700 engines that are equipped with the specified fuel nozzles, ensuring that they meet the airworthiness directives outlined in the Civil Aviation Safety Authority’s schedule. The regulation extends its applicability nationwide across the Commonwealth of Australia, thereby impacting aviation entities and individuals who operate or maintain aircraft equipped with these engines. The compliance requirements outlined in the regulation include an inspection as per SB (CF700) 73-27 during the next hot section inspection after 30 September 1971, and a modification as per SB (CF700) 73-28 before installation in an aircraft following the next reconditioning completed after 31 December 1971. These directives are essential for maintaining the safety and airworthiness of the affected turbine engines.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 106, mandate adherence to certain airworthiness directives concerning the General Electric Turbine Engines - CF700 Series. In this context, AD/CF700/6 pertains to the fuel nozzles of these engines, specifically those with part numbers 37D401657P104, P107, and P109. The directive is applicable to all CF700 engines equipped with these particular fuel nozzles. The relevant documents detailing the required procedures are General Electric Service Bulletins (SB) CF700 72-27 and CF700 73-28, or alternatively, AD/GE-T/18. Under these regulations, the main requirements involve inspections and modifications to ensure the safety and airworthiness of the engines. Section 1 of the directive requires that inspections be conducted in accordance with SB (CF700) 73-27. These inspections must take place during the next hot section inspection after 30 September 1971. Section 2 mandates modifications to be made in line with SB (CF700) 73-28 before the engine is installed in an aircraft following the next reconditioning completed after 31 December 1971. Compliance with these inspections and modifications is crucial for maintaining the operational safety of the aircraft. The obligations imposed by these regulations are clear and specific. Operators of CF700 engines with the specified fuel nozzles must ensure that the required inspections and modifications are carried out at the designated times. This includes having the necessary documentation and following the procedures outlined in the relevant service bulletins or airworthiness directive. Failure to comply with these obligations could result in the engine not meeting the required airworthiness standards, potentially leading to operational issues or safety risks. The Civil Aviation Regulations 1998 also outline the potential consequences for non-compliance with these directives. While the specific penalties or consequences are not detailed in the text, non-compliance with airworthiness directives can generally lead to severe repercussions, including grounding of the aircraft, financial penalties, and potential criminal charges. Operators must adhere strictly to the mandated procedures to avoid these adverse outcomes and ensure the continued safety and legality of their operations.
