B. Description

This Service Bulletin incorporates seven thermal barrier coated (TBC) fire 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 field.

This Service Bulletin also provides instructions to rework the current accessory heat

shield assembly using Repair Document (RD) 032-562.

C. Compliance

Category 3

GE recommends that you do this Service Bulletin at the next shop visit of the

engine/module.

NOTE: 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 fleet.

D. Concurrent Requirements

None.

E. Reason

(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 fire

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 field 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.

F. Approval

The data contained in this Service Bulletin has been reviewed by the appropriate

governmental authority and the repair(s) and modification(s) herein comply with the

K. Interchangeability

The old and new accessory heat shield assembly configurations are physically

interchangeable. However, functional interchangeability is impacted due to the

additional sump fire protection of the new TBC plates and attaching hardware

(bolts, self-locking nuts) required.

NOTE: The reworked accessory heat shield assembly is reidentified per RD 032-562

instructions into the new part number.
