AIRWORTHINESS DIRECTIVE
For the reasons set out in the background section, the CASA delegate whose signature appears below revokes Airworthiness Directive (AD) AD/RB211/18 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.
AD/RB211/18
Amdt 1
Low Pressure Fuel Tube Assembly 8/2000
Applicability: Rolls Royce RB211-535E4-37, -535E4-37/10, -535E4-37/11, -535E4-37/12, -535E4- 37/14, -535E4-37/16, 535E4-37/17, -535E4-37/19, -35E4-37/20, -535E4-37/23,
-535E4-B-37, -535E4-B-37/15, -535E4-B-37/20 and -535E4-B-37/21 engines prior
to serial No 31513 fitted to Boeing 757 series aircraft.
Requirement: Replace Aeroquip manufactured L.P. fuel tubes in accordance with Rolls Royce Service Bulletin RB.211-73-C297 Revision 2 dated May 15, 1998.
Note: UK CAA AD 007-10-97 and AD 008-07-94 refers.
Compliance: Unless previously accomplished; prior to 30 August 2000. This Amendment becomes effective on 10 August 2000.
Background: This amendment raised to mandate replacement of the Aeroquip L.P. fuel tube assembly with IMI Marston L.P. fuel tube assembly. This action is required because fuel leaks can occur in the flexible hose section of the Aeroquip L.P. fuel tube assembly.
This Directive originally raised due to possible fuel leakage at the joint between the HP fuel pump and the L.P. fuel tube from the L.P. filter.
The original issue of this Airworthiness Directive became effective on 5 January 1995.

Delegate of the Civil Aviation Safety Authority 27 June 2000
The above AD is notified in the Commonwealth of Australia Gazette on 12 July 2000.
Overview
The Civil Aviation Regulations 1998, specifically within Part 39, establishes the framework for ensuring the safety of aircraft and aeronautical products within Australian airspace. This legislative instrument addresses the safety concerns associated with Rolls Royce Turbine Engines of the RB211 series, particularly the potential for fuel leaks in the low-pressure fuel tube assembly of certain engine models. The problem identified was the risk of fuel leaks occurring in the flexible hose section of the Aeroquip low-pressure fuel tube assembly, which necessitated the replacement of these components to mitigate the risk of unsafe conditions. The Civil Aviation Safety Authority (CASA), acting as the delegate for the Australian Government, issued this Airworthiness Directive under subregulation 39.1 (1) of the Civil Aviation Regulations 1998 to mandate corrective actions. The primary policy objective is to enhance the safety of air travel by ensuring that any identified unsafe conditions are promptly addressed through specified maintenance and replacement actions.
Scope and Application
This legislative instrument pertains to Airworthiness Directives (AD) issued by the Civil Aviation Safety Authority (CASA) under the Civil Aviation Regulations 1998. Specifically, it revokes AD/RB211/18 and introduces a new AD concerning Rolls Royce RB211 turbine engines, specifically the RB211-535E4-37 series, that are installed in Boeing 757 aircraft. The directive applies to engines manufactured prior to a specified serial number and mandates the replacement of certain fuel tubes to mitigate the risk of fuel leaks. The AD is effective until a specified date, and its application is contingent on compliance with the outlined requirements and instructions, as well as adherence to the compliance timeline. The directive's scope is explicitly limited to the mentioned engine series and aircraft type, and its implementation is overseen by CASA as a delegate of the Commonwealth of Australia.
Key Provisions
The Civil Aviation Regulations 1998 (CAR 1998) include a specific section on Airworthiness Directives (AD) under Part 39. This particular AD, AD/RB211/18 Amendment 1, pertains to Rolls Royce RB211 series turbine engines. Specifically, it targets engines like the RB211-535E4-37, -535E4-37/10, -535E4-37/11, and others, when fitted to Boeing 757 series aircraft. The directive requires the replacement of certain fuel tubes to address safety concerns regarding potential fuel leaks.
The key provision of this AD, as stated in section (a) of the requirement, mandates that the Aeroquip manufactured low-pressure fuel tubes must be replaced. This replacement must follow the instructions outlined in Rolls Royce Service Bulletin RB.211-73-C297 Revision 2 dated May 15, 1998. The directive specifies that this action must be taken unless it has already been completed. The compliance deadline set forth in section (c) requires that this replacement must be carried out prior to 30 August 2000. The amendment itself becomes effective on 10 August 2000.
Entities governed by this AD, primarily those operating Boeing 757 aircraft equipped with the specified Rolls Royce engines, must adhere to the replacement directive. They are obligated to ensure that the fuel tubes are replaced by the compliance date. Failure to comply with the AD could result in severe safety risks, including potential fuel leaks that could compromise flight safety.
The AD imposes both civil and potentially criminal consequences for non-compliance. Civil Aviation Regulations do not typically outline specific penalties in the AD itself but violations can lead to enforcement actions by the Civil Aviation Safety Authority (CASA). These actions can include fines, suspension, or revocation of airworthiness certificates, and other regulatory sanctions. In severe cases where non-compliance results in accidents or significant safety breaches, criminal charges could be pursued under relevant aviation safety and criminal laws, leading to substantial penalties.
