SCHEDULE OF AIRWORTHINESS DIRECTIVES
AIRWORTHINESS DIRECTIVE
For the reasons set out in the background section, the CASA delegate whose signature appears below revokes Airworthiness Directive (AD) AD/RB211/28 and issues the following AD under subregulation 39.1 (1) of CAR 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/RB211/28
Amdt 1
Engine Mounts 6/2001 DM
Applicability: RB211-535E4 engine models as detailed in Rolls Royce Service Bulletin RB.211-71- 5291 Revision 14.
Requirement: Disassemble, inspect and refurbish the engine mounts in accordance with the procedures detailed in Rolls Royce Service Bulletin RB.21-71-5291 Revision 14.
Note 1: CAA (UK) AD 004-08-2000 refers.
Compliance: Engines with cycles in service greater than 5,000 cycles since new; at next engine shop visit after the effective date of this Directive and thereafter at intervals not to exceed 36,000 hours or 12,000 cycles, whichever occurs first.
This Amendment becomes effective on 2 May 2001.
Note 2: This amendment has been issued before the issue date of the original issue of this Directive in response to the late receipt of Revision 14 of the requirement document.
Background: This Directive was originally issued in response to reports of cracks and corrosion being found in RB211 engine mounts. This amendment reflects the manufacturer’s latest revision to the requirement document. Revision 14 of SB 71-5291 details, in part, a 5,000 cycles since new threshold for compliance.
The original issue of this Airworthiness Directive was to become effective on 17 May 2001.

Overview
The Civil Aviation Regulations 1998, amended by F2006B06558, address safety concerns associated with Rolls Royce RB211 series turbine engines, particularly the RB211-535E4 engine models. Enacted by the Commonwealth of Australia, these regulations are overseen by the Civil Aviation Safety Authority (CASA) and were introduced to rectify unsafe conditions identified in the engine mounts of specified aircraft. The policy objective of this legislation is to ensure the airworthiness of aircraft by mandating regular inspection and maintenance of critical engine components. The directive issued under subregulation 39.1(1) of the Civil Aviation Regulations 1998 requires the disassembly, inspection, and refurbishment of engine mounts in accordance with specified procedures, with compliance mandated at intervals not exceeding 36,000 hours or 12,000 cycles, whichever occurs first, starting from engines with cycles in service greater than 5,000 cycles since new.
Scope and Application
The Civil Aviation Regulations 1998 (CAR 1998), specifically under Part 39, mandates the application of Airworthiness Directives (ADs) which are essential in ensuring the safety and airworthiness of aircraft and aeronautical products within the Commonwealth of Australia. This particular AD applies to Rolls Royce RB211-535E4 engine models, as detailed in Rolls Royce Service Bulletin RB.211-71-5291 Revision 14. The directive requires that the engine mounts be disassembled, inspected, and refurbished in accordance with the specified procedures. Compliance with this AD is mandatory for engines that have accumulated more than 5,000 cycles since they were new, with inspections required at the next engine shop visit after the effective date of the directive, and subsequently at intervals not exceeding 36,000 hours or 12,000 cycles, whichever comes first. The AD is issued under subregulation 39.1 (1) of CAR 1998 and is applicable across the national jurisdiction of Australia, extending its reach to all relevant aircraft and aeronautical products within the country.
Key Provisions
The Civil Aviation Regulations 1998, particularly Part 39 - 105, sets out the requirements for airworthiness directives concerning specific aircraft or aeronautical products. In this case, the regulation pertains to the Rolls Royce RB211-535E4 engine models, as detailed in Rolls Royce Service Bulletin RB.211-71-5291 Revision 14. The Airworthiness Directive (AD) AD/RB211/28 mandates actions necessary to address unsafe conditions identified in these engine models. Specifically, section 1 (a) requires the disassembly, inspection, and refurbishment of the engine mounts as outlined in Rolls Royce Service Bulletin RB.21-71-5291 Revision 14. The directive applies to engines with more than 5,000 cycles since new, and compliance must occur at the next engine shop visit following the directive's effective date and then at intervals not exceeding 36,000 hours or 12,000 cycles, whichever comes first.
Entities governed by this AD must adhere to the specific procedural instructions detailed in Rolls Royce Service Bulletin RB.21-71-5291 Revision 14 to ensure that the engine mounts are inspected and refurbished appropriately. This involves dismantling the engine mounts, conducting a thorough inspection for any signs of cracks or corrosion, and performing necessary refurbishments as specified in the service bulletin. The directive is effective from 2 May 2001, as notified in the Commonwealth of Australia Gazette on 26 April 2001.
Failure to comply with this Airworthiness Directive can result in significant legal consequences. Non-compliance may be viewed as a breach of the Civil Aviation Regulations 1998, potentially leading to enforcement actions by the Civil Aviation Safety Authority (CASA). Such breaches can result in civil penalties, which may include fines, or criminal charges, which could lead to imprisonment, depending on the severity of the non-compliance. The maximum penalties are not explicitly stated in the AD, but they are outlined in the broader Civil Aviation Act 1988, which includes provisions for both civil and criminal penalties for non-compliance with airworthiness directives.
