AD/RB211/16 Amdt 1 - Fuel Metering Unit - On Wing Test

Overview

The Civil Aviation Regulations 1998, enacted by the Commonwealth of Australia's Parliament, is a comprehensive piece of legislation designed to regulate and ensure the safety of civil aviation. One specific aspect of this regulation is the issuance of Airworthiness Directives (ADs) which are critical in addressing safety issues that may arise with specific aircraft or aeronautical products. For instance, AD/RB211/16 pertains to Rolls Royce Turbine Engines of the RB211 Series, specifically targeting RB211-524 engine models. This directive was introduced to mandate on-wing testing of the fuel metering unit, ensuring the safety and airworthiness of the engines in question. The policy objective behind such directives is to maintain the highest safety standards in civil aviation by correcting any unsafe conditions identified with particular aircraft or components. The Airworthiness Directives are issued by a delegate of the Civil Aviation Safety Authority (CASA) under the authority granted by subregulation 39.1 (1) of the Civil Aviation Regulations 1998. These directives reflect the need to address identified safety concerns promptly and effectively, ensuring that the aviation industry adheres to stringent safety protocols. The AD/RB211/16, in particular, mandates that fuel metering unit health checks be carried out according to specific procedures, reflecting the importance of maintaining engine reliability and safety. The directive was updated to incorporate changes from the manufacturer's revised requirement document, ensuring that safety measures evolve with technological advancements and new findings.

Scope and Application

The Airworthiness Directive (AD) AD/RB211/16 issued under the Civil Aviation Regulations 1998 by the Civil Aviation Safety Authority (CASA) applies specifically to Rolls Royce RB211-524 engine models that do not incorporate Rolls Royce Service Bulletin RB.211-73-9666, as detailed in Rolls Royce Service Bulletin RB.211-71-9276 Revision 7. The directive mandates that fuel metering unit health checks must be carried out in accordance with the procedures outlined in the specified Rolls Royce service bulletin. The AD is applicable to aircraft within the Australian jurisdiction, and its requirements must be adhered to by aircraft operators and maintenance personnel to ensure compliance with national safety standards. The directive became effective on 14 June 2001 and has been subsequently amended to incorporate additional engine models, as reflected in the Rolls Royce revision. This directive is enforceable across the Commonwealth of Australia and is integral to maintaining the safety and airworthiness of the specified aircraft engines.

Key Provisions

The Civil Aviation Regulations 1998 (CAR 1998), specifically under Part 39 - 106, establish Airworthiness Directives (AD) for ensuring the safety of aircraft and aeronautical products. In this case, AD/RB211/16, amended in 2001, focuses on Rolls Royce RB211 Series turbine engines. According to section (a) of the applicability, the directive applies to RB211-524 engine models that do not incorporate Rolls Royce Service Bulletin RB.211-73-9666, as detailed in Rolls Royce Service Bulletin RB.211-71-9276 Revision 7. The requirement section mandates that fuel metering unit health checks must be carried out in accordance with the procedures outlined in Rolls Royce Service Bulletin RB.211-71-9276 Revision 7. The directive became effective on 14 June 2001, as per section 39.1(1) of CAR 1998. The obligations imposed by AD/RB211/16 are clear and precise. Owners and operators of the affected aircraft must ensure that the specified fuel metering unit health checks are performed on the engines in question. These checks must adhere strictly to the procedures outlined in Rolls Royce Service Bulletin RB.211-71-9276 Revision 7, ensuring that the safety standards set by the Civil Aviation Safety Authority (CASA) are met. The compliance section stipulates that these checks must be completed as detailed in the requirement document, with the directive becoming effective on the date mentioned. The consequences for non-compliance with AD/RB211/16 are significant. Failure to adhere to the requirements of this Airworthiness Directive could lead to serious safety issues, potentially resulting in the grounding of affected aircraft until the necessary checks are performed. Additionally, CASA has the authority to impose fines, penalties, or other sanctions on individuals or entities that do not comply with the directive. The exact penalties are not detailed in the text, but they can include substantial financial penalties and other enforcement actions under the regulatory framework of CAR 1998.
