For the reasons set out in the background section, the CASA delegate whose signature appears below revokes Airworthiness Directive (AD) AD/RB211/19 Amdt 5 and issues the following AD under subregulation 39.1 (1) of CASR 1998. The AD requires that the action set out in the requirement section (being action that the delegate considers necessary to correct the unsafe condition) be taken in relation to the aircraft or aeronautical product mentioned in the applicability section: (a) in the circumstances mentioned in the requirement section; and (b) in accordance with the instructions set out in the requirement section; and (c) at the time mentioned in the compliance section.
Rolls Royce Turbine Engines - RB211 Series
AD/RB211/19
Amdt 6
Combustion Liner 4/2004
Applicability: RB211 engines as detailed in Rolls Royce Alert Service Bulletin (ASB) RB.211-72- AB482 Revision 9 dated 28 July 2003.
Requirement: 1. To detect evidence of combustion liner head section distress which could result in a break-out of combustion, carry out an inspection of the combustion liner in accordance with:
(a) Rolls Royce ASB RB.211-72-AB482 Revision 9, or
(b) As detailed in an inspection procedure approved by CASA in accordance with Civil Aviation Regulation 2A, (4).
2. Incorporate modifications as detailed in Rolls-Royce SB RB211-72-9670 or RB211-72-9764.
Incorporation of the modifications referred to in Requirement 2 of this Directive constitutes terminating action for this Directive.
Note: CAA UK AD G-2003-0011 refers.
Compliance: 1. As detailed in the elected requirement document.
2. At the next shop visit when the 04 module is refurbished or overhauled, but no later than 31 December 2012.
This Amendment becomes effective on 15 April 2004.
Background: This directive was originally issued to address a report of a combustion break-out which resulted in an under cowl fire penetrating the engine pylon. The directive required a periodic inspection of the combustion liner head section and meterpanel assemblies.
This amendment is issued to reduce the inspection interval for RB211-524B engines and also introduces a terminating action.
Rolls Royce Turbine Engines - RB211 Series
AD/RB211/19 Amdt 6 (continued)
Amendment 5 was issued to reflect the latest revision to the manufacturer’s inspection procedure document. The revision, in part, adds engines incorporating RB211-72- 7221 standard combustion liner head sections.
Amendment 4 was issued in July 1997 and reduced the inspection threshold and added the RB211-524D4 engine.
Amendment 5 of the Airworthiness Directive became effective on 7 October 1999. Amendment 4 of this Airworthiness Directive became effective on 17 July 1997.
Amendment 3 of this Airworthiness Directive became effective on 5 December 1996. The original issue of this Airworthiness Directive became effective on 9 November 1995.
James Coyne
Delegate of the Civil Aviation Safety Authority 4 March 2004
The above AD is notified in the Commonwealth of Australia Gazette on 24 March 2004.
Overview
The Civil Aviation Safety Authority (CASA) issued the Airworthiness Directive (AD) AD/RB211/19 Amdt 6 on 4 March 2004, revoking Amendment 5 of the same AD to address safety concerns with Rolls Royce RB211 Series turbine engines. This amendment was introduced to rectify an issue where a combustion liner break-out led to an under cowl fire, potentially penetrating the engine pylon. The AD aims to ensure the airworthiness of these engines by mandating inspections and modifications as specified by Rolls Royce or an approved alternative procedure. Compliance with this directive must occur by the next scheduled shop visit for engine refurbishment or overhaul, but no later than 31 December 2012. This directive is part of CASA's ongoing efforts to maintain the safety and reliability of aircraft in Australia's airspace.
Scope and Application
The Airworthiness Directive (AD) AD/RB211/19 Amdt 6 applies specifically to Rolls Royce RB211 engines, as detailed in Rolls Royce Alert Service Bulletin RB.211-72-AB482 Revision 9 dated 28 July 2003. This legislative instrument is issued under the authority of the Civil Aviation Safety Authority (CASA) and is applicable to the aviation industry, particularly to those operating or maintaining the specified engines. The directive mandates that inspections and modifications be carried out to address potential combustion liner head section distress, which could lead to combustion break-out, thereby ensuring the continued airworthiness of the aircraft involved. Compliance with the directive is mandatory for all operators of the affected engines within the Australian jurisdiction, with specific deadlines outlined for inspections and modifications. The AD extends its reach nationally, impacting all operators within Australia, and is enforced through the Civil Aviation Safety Regulations 1998. Subordinate instruments may further detail specific procedures and requirements, but the primary directive sets forth the essential actions necessary to maintain compliance with aviation safety standards.
Key Provisions
The Airworthiness Directive (AD) AD/RB211/19 Amdt 6, issued by the Civil Aviation Safety Authority (CASA) delegate, outlines specific requirements for the inspection and modification of Rolls Royce RB211 Series turbine engines. Section 4 of the AD specifies that the directive applies to RB211 engines as detailed in Rolls Royce Alert Service Bulletin (ASB) RB.211-72-AB482 Revision 9 dated 28 July 2003. The requirement section mandates two primary actions: first, an inspection of the combustion liner to detect evidence of distress that could lead to a combustion break-out, which must be carried out in accordance with either Rolls Royce ASB RB.211-72-AB482 Revision 9 or an inspection procedure approved by CASA under Civil Aviation Regulation 2A (4). Second, it requires the incorporation of modifications as detailed in Rolls-Royce Service Bulletins RB211-72-9670 or RB211-72-9764. The incorporation of these modifications constitutes the terminating action for this directive.
The AD imposes obligations on the parties and entities it governs, primarily those involved in the maintenance and operation of RB211 engines. Operators must ensure that the specified inspections are conducted in accordance with the outlined procedures and that any identified issues are addressed through the required modifications. Additionally, maintenance personnel must be trained and qualified to perform these inspections and modifications according to the standards set by CASA. These obligations are designed to ensure the continued airworthiness and safety of the aircraft using these engines.
Failure to comply with the provisions of the AD may result in civil or criminal consequences. Specifically, Section 39.1(1) of the Civil Aviation Safety Regulations 1998 (CASR 1998) empowers CASA to impose penalties for non-compliance with ADs. The exact penalties are not specified in the AD itself, but they could include fines or other civil penalties for failure to comply with the inspection and modification requirements. In more severe cases, non-compliance could lead to criminal charges, particularly if the failure results in a safety incident. The maximum penalties for such offences are determined by the relevant aviation safety legislation and could include substantial fines and imprisonment for individuals found guilty of serious breaches.
