AD/DART/27 Amdt 1 - Engine Fuel and Control - Fuel Burner Flow Calibration Checks and Life Limitation

Overview

The Civil Aviation Safety Regulations 1998, enacted by the Commonwealth of Australia, serve to maintain the safety standards within the civil aviation industry. These regulations, specifically within Part 39, are instrumental in addressing potential safety issues and ensuring that all aircraft and aeronautical products adhere to stringent safety protocols. The problem or gap this legislation aimed to address includes ensuring that all aircraft operations and maintenance activities are conducted in a manner that safeguards the public and maintains the integrity of the aviation system. The Civil Aviation Safety Authority (CASA) is the entity responsible for enacting and enforcing these regulations, with the overarching policy objective being to mitigate risks associated with civil aviation activities and to promote a culture of safety and compliance within the industry. The specific Airworthiness Directive mentioned, AD/DART/27, pertains to Rolls Royce Dart engines and was introduced to correct unsafe conditions identified through fuel burner flow variations, which adversely affect the high-pressure turbine discs.

Scope and Application

The Civil Aviation Safety Regulations 1998, specifically Part 39 - 106, establishes a framework for ensuring airworthiness of aircraft and aeronautical products within Australia. This legislative instrument is applicable to aircraft and aeronautical products, including Rolls Royce Dart engines, which are subject to specific airworthiness directives issued by the Civil Aviation Safety Authority (CASA) or its delegate. The geographic and jurisdictional reach of this legislation is national, as it applies to all civil aviation activities within Australia, ensuring compliance with safety standards set by CASA. The Act mandates corrective actions to address unsafe conditions identified in aircraft or aeronautical products, with a particular focus on Rolls Royce Dart engines in this instance. The directive requires adherence to specific actions as outlined in Germany's Airworthiness Directive 2002-365, including fuel burner flow calibration checks and life limitations. The directive became effective on 17 April 2003, with amendments to the original directive issued on 5 August 1998. The applicability of this directive extends to all relevant aircraft and aeronautical products within the specified category, and compliance is mandated within the timeframes provided in the requirement document.

Key Provisions

The Civil Aviation Safety Regulations 1998, specifically Part 39 - 106, introduces an Airworthiness Directive (AD) aimed at ensuring the safety of Rolls Royce Dart engines. This AD, issued under subregulation 39.1(1) of the Civil Aviation Regulations 1998, revokes the previous AD/DART/27 and introduces new requirements to address identified safety issues (subregulation 39.1(1)). The AD mandates specific actions to be taken concerning Rolls Royce Dart engines to mitigate unsafe conditions. This includes performing fuel burner flow calibration checks and imposing life limitations on the engines (subregulation 39.1(2)). The AD applies to all Rolls Royce Dart engines as specified in the requirement document (subregulation 39.1(3)). The directive necessitates compliance with the requirements outlined in Germany's Luftfahrt-Bundesamt (LBA) Airworthiness Directive 2002-365. These requirements include actions to ensure the safe operation of the engines, such as regular inspections and maintenance checks. The AD also specifies that these actions must be performed in accordance with the instructions provided in the requirement document and by a specified compliance date (subregulation 39.1(4)). The obligations imposed by this AD on the parties or entities it governs include conducting repetitive inspections and adhering to the detailed instructions provided in the requirement document. These obligations are critical to ensure the engines' continued airworthiness and safety. Non-compliance with the AD could result in severe consequences, as the directive is designed to prevent adverse effects such as fuel burner flow variations and consequent vibrations that could compromise the high-pressure turbine discs. Failure to comply with the requirements of this AD may result in various civil and criminal consequences. The AD stipulates specific penalties for non-compliance, which may include fines and other enforcement actions. The maximum penalties for breaches of the AD are detailed in the regulations, and non-compliance could potentially lead to the grounding of the affected aircraft until the required actions are completed. This underscores the importance of adhering to the AD to maintain safety standards in aviation.
