AD/DART/20 - High Pressure Turbine Nozzle Guide Vanes

Overview

The Civil Aviation Regulations 1998, as amended through the legislative instrument F2006B08706, were enacted by the Australian Government to regulate civil aviation safety and to ensure compliance with international standards. This particular regulation was introduced to address issues related to the airworthiness of Rolls Royce Turbine Engines, specifically the Dart Series. The policy objective of this regulation is to maintain the highest safety standards in civil aviation, ensuring that aircraft engines meet specific airworthiness requirements to prevent malfunctions and ensure passenger safety. The regulation was enacted by the Parliament of Australia and is administered by the Civil Aviation Safety Authority, which is tasked with enforcing compliance with these safety directives to maintain the integrity of Australia's aviation industry.

Scope and Application

The Civil Aviation Regulations 1998, under PART 39 - 106, applies specifically to all Dart RDa-6 series engines used in civil aviation within Australia. This regulation is enforced by the Civil Aviation Safety Authority and is part of a broader effort to ensure that aviation operations maintain the highest safety standards. The scope of this legislation is to mandate certain actions or compliance measures for the high-pressure turbine nozzle guide vanes of the specified engines, either by following the actions detailed in Rolls Royce SB Da 72-451 Rev 5 or by adhering to the requirements outlined in AD/RRT/33. The directive ensures that any modifications, inspections, or maintenance actions taken on these engines align with the stipulated safety directives. The legislation applies nationally, covering all entities and persons operating or maintaining Dart RDa-6 series engines within the Australian jurisdiction, ensuring a uniform approach to engine safety across the country. No specific exclusions or exemptions are mentioned within the text of this regulation, implying that it is universally applicable to the targeted engines.

Key Provisions

The Civil Aviation Regulations 1998, particularly Part 39 - 106, addresses the Airworthiness Directives concerning Rolls Royce Turbine Engines of the Dart Series. Specifically, AD/DART/20 pertains to high-pressure turbine nozzle guide vanes for all Dart RDa-6 series engines. The directive requires compliance with either Rolls Royce Service Bulletin (SB) Da 72-451 Rev 5 or AD/RRT/33, ensuring that the actions taken follow the detailed instructions in the respective requirement document. This directive mandates certain actions or inspections to be performed on the specified engines to maintain their airworthiness. Entities governed by the Civil Aviation Regulations 1998, including operators and maintenance providers of Dart RDa-6 series engines, must adhere to the provisions outlined in AD/DART/20. This entails ensuring that the high-pressure turbine nozzle guide vanes are inspected and maintained according to the specified Rolls Royce bulletin or the referenced airworthiness directive. Operators must keep thorough records of all actions taken to comply with these requirements, demonstrating adherence to the regulatory standards set forth by the Civil Aviation Safety Authority (CASA). Failure to comply with the requirements of AD/DART/20 may result in significant consequences. Non-compliance could potentially lead to the grounding of affected aircraft, which in turn could affect flight operations and passenger safety. Under the Civil Aviation Act 1988, CASA has the authority to enforce penalties for non-compliance with airworthiness directives. These penalties can include substantial fines and, in severe cases, the suspension or revocation of the operator’s licence. The exact penalties depend on the nature and extent of the non-compliance, but they are designed to ensure that all parties maintain the highest standards of aviation safety.
