AD/CF34/2 - Fuel Control Bypass Valve

Overview

The Civil Aviation Regulations 1998, enacted by the Australian Government, aim to ensure the safety and efficiency of civil aviation within Australia. Specifically, Part 39, Section 106, includes the Airworthiness Directives (AD) which establish mandatory requirements for the maintenance and operation of aircraft to maintain their airworthiness. One such directive, AD/CF34/2, addresses issues related to General Electric Turbine Engines of the CF34 Series, focusing on the fuel control bypass valve. This directive was introduced to rectify a problem identified by the Federal Aviation Administration (FAA) in the United States, which mandated the replacement of the fuel control by-pass piston to prevent engine flameout or uncommanded power rollback caused by contamination. The policy objective is to ensure the safety of aircraft operations by adhering to international safety standards and directives. The Australian Civil Aviation Safety Authority (CASA) adopts and enforces these ADs to align with the FAA’s regulations, ensuring that Australian-registered aircraft meet the same safety standards. By implementing AD/CF34/2, CASA mandates compliance with FAA AD 88-06-07, specifically requiring that the necessary actions be completed before 30 September 1988. This directive is critical in maintaining the safety and reliability of aircraft equipped with CF34-1A and -3A engines installed in Canadair CL-600-2A12 and CL-600-2B16 aircraft.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 106, applies to the Civil Aviation Safety Authority’s Schedule of Airworthiness Directives concerning the General Electric Turbine Engines of the CF34 Series. This legislative instrument mandates that CF34-1A and -3A engines installed in Canadair CL-600-2A12 and CL-600-2B16 aircraft must comply with FAA AD 88-06-07, amendment 39-5866, paragraph (A) items (1) and (2). This requirement necessitates the replacement of the fuel control bypass piston to prevent engine flameout or uncommanded power roll back caused by contamination of the fuel control. The compliance date for these actions is before 30 September 1988. The directive extends its reach to the specified aircraft and engines within the Australian jurisdiction, ensuring adherence to the safety standards set forth by the Federal Aviation Administration. The regulations do not specify any exclusions or exemptions within the text provided, thus encompassing all applicable aircraft within its scope.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 106, outlines the Civil Aviation Safety Authority's Schedule of Airworthiness Directives. One of these directives, AD/CF34/2, pertains to General Electric Turbine Engines of the CF34 Series, more precisely addressing the fuel control bypass valve for engines CF34-1A and -3A installed in Canadair CL-600-2A12 and CL-600-2B16 aircraft (Part 39 - 106). This directive requires compliance with the FAA AD 88-06-07 amendment 39-5866, which mandates the replacement of the fuel control bypass piston to prevent engine flameouts or uncommanded power rollbacks caused by contamination of the fuel control (Part 39 - 106). Compliance with these provisions is crucial, and it must be achieved before 30 September 1988. The Act imposes specific obligations on the entities governed by these regulations. For instance, the operators of aircraft equipped with the specified engines must ensure that the required actions outlined in the FAA directive are implemented. This involves the timely replacement of the fuel control bypass piston as per the stipulated guidelines to maintain the airworthiness of the aircraft and to mitigate risks associated with engine performance issues (Part 39 - 106). Failure to comply with these requirements could result in serious safety hazards, making adherence to the directive a critical operational responsibility for aircraft operators. Violation of the provisions set out in Part 39 - 106 of the Civil Aviation Regulations 1998 can lead to significant consequences. The Act does not specify particular offences or penalties within the text provided, but non-compliance with airworthiness directives is generally considered a serious matter under aviation law. Typically, such breaches could result in enforcement actions, fines, and potential grounding of non-compliant aircraft. The seriousness of these consequences underscores the importance of adhering to the regulatory requirements to ensure the safety and reliability of air travel.
