AD/CF700/2 - No. 1 Bearing

Overview

The Civil Aviation Regulations 1998, enacted by the Commonwealth of Australia, were introduced to establish comprehensive regulations governing civil aviation safety within the country. This includes the establishment of standards for airworthiness directives to ensure the safety and reliability of aircraft components, including turbine engines. The regulations are administered by the Civil Aviation Safety Authority (CASA) and serve to address the need for standardised safety protocols in civil aviation, aiming to prevent accidents and ensure the highest levels of safety for passengers and crew. A specific legislative instrument, F2006B08506, pertains to the General Electric Turbine Engines - CF700 Series, establishing a directive for the no. 1 bearing in CF700-2C and CF700-2D engines, mandating compliance before installation following specific overhaul criteria. This directive is part of the broader policy objective to maintain stringent safety standards in aviation.

Scope and Application

The Civil Aviation Safety Authority (CASA) Regulations 1998, specifically Part 39 - 106, address the airworthiness directives for certain aircraft components, including turbine engines. The legislation applies to General Electric CF700 Series turbine engines, particularly those with serial numbers falling within the specified ranges. This regulatory framework ensures that the designated CF700-2C and CF700-2D engines, with their respective serial number ranges, adhere to the safety standards outlined in the directives. Compliance is mandatory before the engines are installed in aircraft following their next overhaul completed after 31 May 1971. The directives reference specific service bulletins and other regulatory instruments, which may extend or refine the application of the primary legislation. The geographic and jurisdictional reach of these regulations is national, applying across the Commonwealth of Australia to ensure consistent safety standards in civil aviation. There are no stated exclusions, exemptions, or thresholds in this particular directive, meaning all applicable engines must comply with the outlined safety requirements.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 106, details the Civil Aviation Safety Authority (CASA) schedule of airworthiness directives, with one such directive being AD/CF700/2. This directive pertains to the General Electric Turbine Engines of the CF700 Series, more precisely the No. 1 Bearing (sections 106.01 and 106.02). The directive applies to CF700-2C engines with serial numbers ranging from 245-001 to 245-429, and CF700-2D engines with serial numbers from 299-001 to 299-102 (section 106.03). Compliance with this directive is required before these engines are installed in an aircraft following their next overhaul after 31 May 1971, in accordance with the General Electric Service Bulletin (CF700) 72-76 or AD/GE-T/6B (section 106.04). The obligations and requirements imposed by this airworthiness directive are clear and specific. Operators of the affected engines must ensure that they adhere to the compliance guidelines provided by the General Electric Service Bulletin (CF700) 72-76 or AD/GE-T/6B. This involves conducting the necessary inspections, repairs, or replacements as detailed in these documents. Furthermore, operators must ensure that the engines are not used in an aircraft until they have undergone the required overhaul and the compliance measures are satisfactorily completed (section 106.05). These obligations are crucial for maintaining the safety standards required by CASA and ensuring the airworthiness of the aircraft. Failure to comply with the provisions of AD/CF700/2 could result in serious consequences. According to the regulations, breaches may lead to enforcement actions by CASA, which could include fines, penalties, and other civil or criminal consequences (section 106.06). While the specific maximum penalties are not detailed in the provided text, it is understood that non-compliance with CASA directives can have significant repercussions, potentially affecting the operational status and legality of the aircraft involved. Ensuring adherence to these directives is therefore imperative for operators to avoid any adverse legal or safety outcomes.
