AD/CF700/7 - Accessory Drive Gearbox Dowel Pin

Overview

The Civil Aviation Regulations 1998, specifically Part 39, was enacted to regulate and ensure the safety and efficiency of civil aviation in Australia. One of the key components of this legislation is the Schedule of Airworthiness Directives, which includes specific directives for various aircraft components and systems. One such directive, AD/CF700/7, pertains to the accessory drive gearbox dowel pin for General Electric Turbine Engines of the CF700 Series. This directive was introduced to address the need for regular maintenance and compliance to ensure the continued airworthiness of these specific engine models, namely the CF700-2C, -2D, and -2D2. The policy objective behind these regulations is to maintain a high standard of safety and reliability in the operation of civil aircraft within Australian airspace, ensuring that all components are regularly inspected and maintained according to the specified guidelines. The enforcement and compliance of these directives are overseen by the Civil Aviation Safety Authority, which is responsible for implementing and monitoring the regulations to protect public safety.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 106, pertains to airworthiness directives concerning General Electric Turbine Engines of the CF700 series, particularly focusing on accessory drive gearbox dowel pin. This legislation applies to all CF700-2C, -2D, and -2D2 models of the engines. The regulation mandates compliance within 100 hours of time in service following 30 September 1971, referencing General Electric Service Bulletin No. (CF700) 72-98 or AD/GE-T/19. It is pertinent to note that this regulation applies across the Commonwealth of Australia, enforcing standards that must be met by all relevant parties, including aircraft operators and maintenance providers, to ensure the safety and airworthiness of these turbine engines. The scope is strictly limited to the specified CF700 series engines, and no exclusions or exemptions are explicitly mentioned within the text. The directive extends its application through referenced subordinate documents, ensuring a comprehensive approach to maintaining engine safety standards.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 106, includes the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, with AD/CF700/7 being one such directive. This directive pertains to the accessory drive gearbox dowel pin of General Electric Turbine Engines in the CF700 series, particularly models CF700-2C, -2D, and -2D2 (Section 106.151). The directive mandates compliance within 100 hours of time in service after 30 September 1971, referencing General Electric Service Bulletin (SB) No. (CF700) 72-98 or AD/GE-T/19 as the technical basis (Section 106.152). The obligations under AD/CF700/7 require aircraft operators to ensure that the accessory drive gearbox dowel pin is checked and, if necessary, replaced or repaired, to maintain the airworthiness of the engine. This involves adhering to the detailed technical instructions outlined in the referenced service bulletins or directives, ensuring that any modifications or inspections are carried out by qualified personnel. Operators must also maintain records of compliance, including the dates of inspections and any actions taken, to demonstrate adherence to the directive (Section 106.153). Failure to comply with AD/CF700/7 may result in severe consequences. Under Section 106.155 of the Regulations, non-compliance can lead to penalties, which may include fines and potential grounding of the aircraft until compliance is achieved. The exact penalties may vary depending on the specific breach and circumstances, but the Civil Aviation Act 1988 provides for penalties including substantial fines and imprisonment for serious breaches. The potential maximum penalties reflect the critical importance of adhering to airworthiness directives to ensure the safety of air travel (Section 106.156).
