1. Planning Information

A. Effectivity

(1) All BR700-710A1-10 Engines.

Modules M61-148, M61-158, M61-162, M61-168, M61-169, M61-176, M61-179,

M61-184, M61-188, M61-190, M61-195, M61-196, M61-197 and M61-203

(Accessory Gearbox Module).

(2) All BR700-710A2-20 Engines.

Modules M61-149, M61-163, M61-171, M61-177, M61-180, M61-185, M61-198,

M61-199 and M61-204 (Accessory Gearbox Module).

(3) All BR700-710C4-11 Engines.

(a) For engines which have hardware configuration standard 710C4-11

engraved on the engine data plate (Service Bulletin

SB-BR700-72-101466 standard not incorporated).

Modules M61-187 and M61-205 (Accessory Gearbox Module).

(b) For engines which have hardware configuration standard 710C4-11/10

engraved on the engine data plate (Service Bulletin

SB-BR700-72-101466 standard incorporated).

Module M61-202 (Accessory Gearbox Module).

B. Concurrent Requirements

None.

C. Reason

Premature wear on the fuel pump splined coupling has been identified during

in-service inspection. There is the requirement to replace the fuel pump

splined coupling at a defined interval (see paragraph 1.E. Compliance) before

the fuel pump splined coupling is damaged due to high wear.

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

the Manpower from 4 hours to 10 hours and to include the old standard of fuel

pump splined coupling, P/N BRR52639.

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

the Effectivity, to make the Non-Modification Service Bulletin applicable for

all engines.

D. Description

This Non-Modification Service Bulletin includes the procedure for the

R replacement of the fuel pump splined coupling.

NOTE: The Accomplishment Instruction of this Non-Modification Service

Bulletin is divided into two INSTRUCTIONs as follows:

INSTRUCTION I - Applicable for engines "In Service".

INSTRUCTION II - Applicable for engines "At Overhaul/Shop Visit".

E. Compliance

ALERT

This Non-Modification Service Bulletin must be accomplished on engines before

the engine has accumulated 4000 flight hours since new and must be repeated at

repeat intervals of not more than 4000 flight hours after the previous

accomplishment.

NOTE: If engines have accumulated 4000 flight hours or more since new at the

R this Non-Modification Service Bulletin was time the Initial Issue of

issued, this Non-Modification Service Bulletin must be accomplished on

engines within 250 flight hours and must be repeated at repeat

intervals of not more than 4000 flight hours after the previous

accomplishment

NOTE: If engines will accumulate 4000 flight hours or more since new before

its next A-Check, this Non-Modification Service Bulletin must be

accomplished on engines within 250 flight hours and must be repeated at

repeat intervals of not more than 4000 flight hours after the previous

accomplishment

NOTE: If engines have had the fuel pump splined coupling replaced as a part

of the splined coupling sampling program, this Non-Modification Service

Bulletin must be accomplished on engines before the engine has

accumulated 4000 flight hours since the last fuel pump splined coupling

replacement and must be repeated at repeat intervals of not more than

4000 flight hours after the previous accomplishment.
