A. Effectivity

BR700-715A1-30, BR700-715B1-30 and BR700-715C1-30 Engines.

For all engines which do not have the Service Bulletin SB-BR700-72-101155

standard and do not have the Service Bulletin SB-BR700-72-101683 standard

incorporated.

Non-Modular.

B. Concurrent Requirements

None.

C. Reason

A crack was detected on a Low Pressure (LP) compressor booster rotor during a

spin test at high life. The LP compressor booster rotor was part of the first

production batch installed on BR715 engines.

There is the requirement to instruct a precautionary local Fluorescent

Penetrant Inspection (FPI) of the potentially affected LP compressor booster

rotors.

Revision 1 of this Non-Modification Service Bulletin had been issued to extend

the quantity of potentially affected LP compressor booster rotors in the

Description and to revise the Compliance.

Revision 2 of this Non-Modification Service Bulletin had been issued to add

the use of alternative fluorescent high sensitivity post-emulsified penetrant

(Material No. 6/155) for the Fluorescent Penetrant Inspection (FPI) for

engines "In Service".

R Revision 3 of this Non-Modification Service Bulletin had been issued to

include PART 2 which instructs the rework of the Low Pressure (LP) compressor

booster rotor front flange scallops for engines at overhaul/shop visit in

accordance with Service Bulletin SB-BR700-72-101683.

Revision 4 of this Non-Modification Service Bulletin has been issued to

include the inspection of the Low Pressure (LP) compressor booster rotor front

flange scallops for engines at overhaul/shop visit, if the level of engine or

module disassembly does not allow the LP compressor booster rotor to be

reworked in accordance with Service Bulletin SB-BR700-72-101683.

D. General

NOTE: In order to reduce the potential for multiple-engine in-flight

shutdown, power loss, or other anomaly due to maintenance error,

Rolls-Royce Deutschland recommends that Operators avoid performing

maintenance on multiple engines installed on the same aircraft at the

same time. If it is not possible to avoid maintenance on more than one

engine of an aircraft at the same time, Rolls-Royce Deutschland

recommends that additional controls are applied in order to ensure that

maintenance tasks have been completed as defined.

WARNING: YOU MUST BE CAREFUL WHEN YOU DO WORK ON THE ENGINE PARTS AFTER THE

ENGINE IS STOPPED. THE ENGINE PARTS CAN STAY HOT FOR ALMOST ONE

HOUR.

WARNING: DO NOT TOUCH HOT PARTS WITHOUT APPLICABLE GLOVES. HOT PARTS CAN

CAUSE AN INJURY. IF YOU GET AN INJURY, PUT IT IN COLD WATER FOR TEN

MINUTES AND GET MEDICAL AID.
