Overview

The Civil Aviation Regulations 1998, specifically PART 39 - 106, includes a legislative instrument F2006B08496 that was enacted to address concerns about the airworthiness of certain turbine engines. This particular directive pertains to the General Electric CF6 Series engines, more specifically the CF6-80A/A2, -80A1/A3 models. The objective of this directive is to ensure safety by mandating inspections of the first stage high pressure turbine discs to identify any blemishes in the forward and aft embossment radii. This requirement is derived from a Service Bulletin issued by General Electric and referenced in FAA AD 86-15-04 Amdt 39-5353, aiming to mitigate potential risks that could affect the service life of these critical components. Compliance with this directive is enforced to maintain the highest safety standards in civil aviation as overseen by the Civil Aviation Safety Authority. This legislative instrument was introduced by the Commonwealth of Australia, reflecting a commitment to stringent aviation safety protocols. The policy objective underpinning this directive is to preemptively address potential mechanical failures that could compromise the integrity and reliability of turbine engines, thereby safeguarding air travel safety. The directive is part of a broader regulatory framework designed to ensure that all civil aviation activities within Australia conform to the highest safety standards, overseen by the Civil Aviation Safety Authority.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 106, pertains to the Civil Aviation Safety Authority's schedule of airworthiness directives, including AD/CF6/7 concerning General Electric Turbine Engines of the CF6 Series. This directive applies to CF6-80A/A2 and -80A1/A3 engines, requiring the inspection of the first stage high pressure turbine discs to ensure they meet the specified embossment radii as outlined in General Electric's Service Bulletin (SB) (CF6-80A Series) A72-446. The directive mandates adherence to the requirements set forth in the aforementioned reference document, FAA AD 86-15-04 Amendment 39-5353. This regulatory measure aims to maintain the airworthiness of these turbine engines by ensuring that any blemishes in the specified areas do not compromise the service life and safety of the discs. The regulations apply to all operators of the specified engines within the Commonwealth of Australia, ensuring compliance across the national jurisdiction.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 106, contain the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives, which include detailed requirements for maintaining the airworthiness of certain aircraft components. For example, AD/CF6/7 pertains to the inspection of first stage high pressure turbine discs in General Electric CF6 Series engines, such as the CF6-80A/A2 and -80A1/A3 variants (section 9/86). The key requirement of this directive is to inspect these turbine discs in accordance with the specifications laid out in General Electric's Service Bulletin (SB) (CF6-80A Series) A72-446. This inspection is necessary to ensure that there are no blemishes in the forward and aft embossment radii of the turbine discs, as such blemishes can potentially affect the service life of the discs. Compliance with AD/CF6/7 is mandatory for all parties operating aircraft equipped with the specified CF6 Series engines. Operators and maintenance personnel must adhere strictly to the inspection protocol as detailed in General Electric's Service Bulletin A72-446 and the referenced FAA AD 86-15-04 Amendment 39-5353. This ensures that any potential issues with the turbine discs are identified and addressed promptly, thereby maintaining the safety and airworthiness of the aircraft. Failure to comply with the requirements set forth in AD/CF6/7 can result in severe consequences. CASA may take enforcement action against operators who do not adhere to the inspection and maintenance directives. The potential penalties for non-compliance can include fines, suspension or revocation of aircraft operating certificates, and other legal repercussions. The specific penalties depend on the severity and frequency of the non-compliance, but they are intended to ensure that all safety directives are rigorously followed to protect public safety in aviation.
