AD/RB211/10 Amdt 1 - High Pressure Compressor Disc

Overview

The Civil Aviation Regulations 1998, specifically under Part 39 - 106, address the safety and airworthiness of aircraft and related components, ensuring compliance with international standards. The Civil Aviation Safety Authority, which is the regulatory body for civil aviation safety in Australia, established these regulations to maintain a high level of safety within the civil aviation sector. One such regulation is the Airworthiness Directive (AD) pertaining to Rolls Royce Turbine Engines of the RB211 series. AD/RB211/10 Amendment 1 pertains to the high-pressure compressor disc and was enacted to address identified issues with specific engine components that could potentially compromise safety. The policy objective behind this directive is to mandate the removal from service of specific high-pressure compressor disc assemblies in RB211-524 Series Engines, as identified by serial number in Rolls Royce Service Bulletin RB211-72-A7774 Revision 2 Appendices 3 and 4. This action is necessary to mitigate risks associated with the identified components, thereby enhancing overall aviation safety. The directive references FAA AD 86-15-01 Amendment 39-5346 for additional compliance guidelines. The regulation has been updated to reflect the manufacturer's latest revisions, expanding the list of affected components to ensure comprehensive safety measures are in place.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 106 Civil Aviation Safety Authority Schedule of Airworthiness Directives, govern the safety and maintenance requirements for aircraft and their components within Australia. This legislative instrument applies to Rolls Royce RB211-524 Series engines, impacting the aviation industry by mandating specific maintenance actions to ensure airworthiness. The regulation's geographic and jurisdictional reach is national, enforced by the Civil Aviation Safety Authority under the Commonwealth of Australia. The requirement under AD/RB211/10 Amendment 1 involves the removal from service of high-pressure compressor disc assemblies identified by serial number in Rolls Royce Service Bulletin RB211-72-A7774 Rev 2 Appendices 3 and 4. Compliance with this directive is to be achieved in accordance with the Requirement Document, and it references FAA AD 86-15-01 Amendment 39-5346 for additional context. The directive has been updated to reflect the manufacturer's latest revisions, which have expanded the number of affected discs, thus extending the scope of the compliance obligations for entities operating these engines within Australia.

Key Provisions

The Civil Aviation Regulations 1998, particularly Part 39 - 106, mandate that specific Rolls Royce RB211-524 Series engines must be removed from service if they contain high pressure compressor disc assemblies identified by serial numbers in Rolls Royce Service Bulletin RB211-72-A7774 Rev 2 Appendices 3 and 4. This directive is detailed in AD/RB211/10 Amendment 1 (section 39-106). The directive applies directly to the identified engines, requiring their removal from service to ensure safety standards are met. Entities and parties governed by this Act, including aircraft operators and maintenance providers, must adhere to the compliance requirements set forth in the Requirement Document. This includes verifying the serial numbers of the high pressure compressor discs against the specified lists and taking the necessary action to remove any affected engines from service. The obligation is clear: affected engines must not be used until they are compliant with the directive, ensuring the safety of the aircraft and its passengers. Failure to comply with the provisions of this directive can result in serious consequences. The Civil Aviation Safety Authority (CASA) may take enforcement actions against non-compliant entities. Civil penalties may include fines up to a significant amount as stipulated by the regulations. Additionally, criminal charges may be brought against individuals who knowingly permit the operation of non-compliant aircraft, which could result in imprisonment. The precise penalties are outlined within the Civil Aviation Regulations 1998 and may vary based on the severity and circumstances of the breach.
