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. Revision 2 of this Non-Modification Service Bulletin had R been issued to revise the Effectivity, to make the Non-Modification Service Bulletin applicable for all engines.
