Concurrent Requirements The following Rolls-Royce RB211 Service Bulletin (Modification) must be fitted concurrently with this Service Bulletin: ENGINE - HP/IP BEARING SUPPORT - INTRODUCTION OF AN HP/IP TURBINE BEARINGS SUPPORT STRUCTURE WITH REVISED OIL AND AIR SERVICE TUBES AND ASSOCIATED INSULATED HEATSHIELD COVERS - MOD.72-F227Printed in Great Britain



# RB.211−72−F227 Page 1 of 17 Mar 30/07 Oct. 8/07 R72-D119 Engine - HP/IP turbine bearing support - Introduction of revised oil tube end fittings
C. Reason (1) Problem Cracking of the HP/IP turbine bearing support structure oil and air service tube insulation blankets can occur, which may result in frettage of the tube wall. In addition, tubes previous modified by the deletion of the outer insulation jacket from the oil feed, scavenge and vent service tubes, can be improved to restore the optimum configuration for reduced carbon formation. (2) Evidence Cracking of the insulation jackets has been observed during routine overhaul, and tube frettage, leading to oil leaks, has been experienced by operators. (3) Substantiation The changes introduced by this Service Bulletin have been the subject of satisfactory engineering analysis including a trial installation of the revised service tubes and insulated heatshields on an existing HP/IP turbine bearings support structure. In addition, HP/IP support structure service tubes with heatshields that feature a sliding expansion joint have completed extensive development endurance testing and have also proven to be durable on another RB211 Trent engine type. (4) Objective Incorporation of this Service Bulletin (Modification) is designed to maintain reliability. (5) Effect of Bulletin on: (a) Operation Not affected (b) Maintenance Not affected (c) Overhaul Affected (see 1.L., Other Publications Affected).Printed in Great Britain



# RB.211−72−F227 Page 2 Mar 30/07 Oct. 8/07 R(d) Repair Schemes Affected (Repairs will be revised to include the new part(s) introduced by this Service Bulletin). (e) Interchangeability Affected (see 1.B., Concurrent Requirements). D. Description (1) This Service Bulletin introduces a revised HP/IP turbine bearings support structure featuring changes to the oil and air service tube assemblies and insulated heatshield covers, to allow for the thermal expansion of the heatshield covers relative to the tubes. The changes will reduce the possibility of frettage damage occurring between each tube and associated inner and outer heatshield cover. Additionally, geometric changes to the profile of the service tube assemblies are introduced to improve the oil and air flow through the tubes and reduce the possibility of carbon forming in the tube bores. The revised HP/IP turbine bearings support structure is similar to the existing item but for the following changes: (a) Revised insulated heatshield covers and blankets are introduced on the three oil and four air service tubes. Outer covers are also introduced at the previously deleted outer positions on the oil tubes. The revised heatshields feature the following changes: (i) The heatshield cover is now a one-piece item produced from two welded half-shells, replacing the existing pair of heatshields at each position. (ii) The retaining clips, rivets and stiffeners, adjacent to the centre ferrule, are deleted to allow the heatshields to expand into new retaining sleeves that are introduced on each tube assembly. A new stiffener ring is welded to the end of the heatshield cover to provide a sliding contact face with the retaining sleeve. (iii) The heatshield covers are increased in length to provide improved insulation of the tube assemblies towards the centre ferrule and the axial length of the thermal insulation blankets are increased to suit.Printed in Great Britain



# RB.211−72−F227 Page 3 Mar 30/07 Oct. 8/07 R(b) The three oil and four air service tube assemblies are revised with the following changes: (i) The tube geometry is now straighter along the tube length compared to existing, to improve oil and air flow and reduce the possibility of carbon formation within the tube bore. (ii) The centre elbow that connects the inner and outer tube sections of tube assembly is replaced by a straight centre ferrule with an improved surface texture limit of 0,8 micrometers applied to the ferrule bore. (iii) Two new retaining sleeves are welded to each end of the centre ferrule; the revised heatshield covers are able to slide in the sleeves to accommodate thermal movement. (iv) The outermost threaded adaptor on the oil service tubes, which interface with the external oil feed, scavenge and vent tube assemblies, are revised to now feature a parallel internal bore with a surface texture limit of 0,8 micrometers applied, to improve flow through the outer section of the oil service tube assemblies. (2) Existing HP/IP turbine bearings support structures may be reworked, see 3., Accomplishment Instructions. (3) Modification kit parts are provided to accomplish rework of existing HP/IP turbine bearings support structures. The air service tubes are bolted assemblies and the oil service tubes are welded to the support structure, for which welding rings are supplied.
