Mar 30/07

R Oct. 8/07
72-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

(b) Maintenance

(c) Overhaul

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

Page 3

Mar 30/07

R Oct. 8/07
(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.
