B. D e s c r i p t i o n This Service Bulletin incorporates seven thermal barrier coated (TBC) fi re shields (plates) in the accessory heat shield assembly. These TBC plates will be installed in new accessory heat shield assemblies. The affected accessory heat shield assemblies will be reworked to incorporate the seven TBC plates in the fi eld. This Service Bulletin also provides instructions to rework the current accessory heat shield assembly using Repair Document (RD) 032-562.

C. C o m p l i a n ce Category 3 GE recommends that you do this Service Bulletin at the next shop visit of the engine/module. N O T E : This Service Bulletin can be accomplished in shop. This Service Bulletin is offered to improve the reliability or performance of your GE product, or to help prevent the occurrence of the event or condition described in this Service Bulletin. If the operator elects not to participate in the bulletin, that decision will be taken into consideration by GE in evaluating future product performance issues that may arise in the operator’s fl eet. D. C o n c u rre n t Re q u i re m e n ts None. E. R e a s o n (1) Objective: To rework parts and improve reliability. (2) Condition: The old accessory heat shield assembly incorporates three TBC plates. However, one event caused secondary damage in the accessory compartment integrated drive generator (IDG) from direct impingement of a B-sump fi re event caused by improper maintenance. (3) Cause: The old titanium accessory heat shield assembly leaves a large area above the sensitive accessories such as the IDG and the main fuel pump (MFP) without adequate protection. (4) Improvement: The new accessory heat shield assembly was redesigned to provide coating coverage on a more extensive area on top of the accessory heat shield. Existing accessory heat shield assemblies in the fi eld will be reworked to incorporate the seven TBC plates. The added TBC plates reduce the risk of high temperature air/gas entering to the accessory compartment and creating secondary hazards. (5) Substantiation: Substantiation is by analysis and comparative analysis.

I n te rc h a n g e a b i l i ty The old and new accessory heat shield assembly con fi gurations are physically interchangeable. However, functional interchangeability is impacted due to the additional sump fi re protection of the new TBC plates and attaching hardware (bolts, self-locking nuts) required. N O T E : The reworked accessory heat shield assembly is reidenti fi ed per RD 032-562 instructions into the new part number. L. S of twa re Acco m p l i s h m e n t S u m m a ry Not applicable. 2.
