Page 2 of 11 GE recommends that you do this Service Bulletin at the next shop visit of the engine/module and not at quick turn.
Impact B This recommendation is to address a condition that may result in an Increased Rate of In-Flight Shutdowns (IFSD), Take-Off Aborts (TOA), Air Turn Backs (ATB) or Diversions (DIV).
NOTE:This Service Bulletin can be done 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 improve reliability and reduce significant events.

3. ACCOMPLISHMENT INSTRUCTIONS A. General
(1) Disassemble the TGB assembly to get access to the radial gearshaft (1, serialFigure 1) number. Disassembly instructions for the TGB assembly have not changed. Refer to the GE90-100 EM, 72-62-00, DISASSEMBLY 001.
(2) Do a check of the radial gearshaft (1, serial number and do as follows:Figure 1)
(a) If the radial gearshaft serial number does not belong to one of the groups below, then this Service Bulletin is not applicable.
*Serial numbers listed in paragraph 4., , Table 1.APPENDIX - A *Serial numbers starting with the prefix FIAAXXXX.
*Serial numbers starting with a prefix from FIA05XXX to FIA09XXX.
*Serial numbers starting with a prefix from FIA0AXXX to FIA0NXXX.
(b) If the radial gearshaft serial number belongs to one of the groups below, continue with step 3.A.(3) of this Service Bulletin.
*Serial numbers listed in paragraph 4., , Table 1.APPENDIX - A *Serial numbers starting with the prefix FIAAXXXX.
*Serial numbers starting with a prefix from FIA05XXX to FIA09XXX.
*Serial numbers starting with a prefix from FIA0AXXX to FIA0NXXX.
(3) Do an inspection of the affected radial gearshaft (1, as follows:Figure 1)
(a) Do an inspection of the chamfers on the toe and heel sides of the teeth (Figure 1, DETAIL D). Put a mark on all chamfers for presence of raised material and/or rework and do as follows:
1 Do an inspection by scribe 0.01181 inch (0.30 mm) radius of all chamfers of the teeth for raised material.
2 Do a visual inspection with a suitable magnification (38X minimum) of all rootland chamfers of the teeth on the toe side for rework and/or raised material.
3 Do a visual inspection with a 10X lens of all rootland chamfers of the teeth on the heel side for raised material.
NOTE:Figure 2 and show examples of rootland chamfer radial gearshafts.Figure 3 4 Record the inspection results in paragraph 5., , Table 2. Write theAPPENDIX - B necessary data and number of chamfers where you find presence of rework or raised material.
(4) Disposal of the radial gearshaft (1, is as follows:Figure 1)
(a) If you find raised material on one or more chamfers in any inspected areas, replace the radial gearshaft.
(b) If you find rework on the toe side rootland chamfer, replace the radial gearshaft.
(c) If the radial gearshaft passed the inspection, do as follows:
1 Identify that the radial gearshaft passed the inspection and is installed in the TGB assembly as follows:
a Put an SB 72-0857 marking next to the existing radial gearshaft part number.
Refer to the SPM, 70-16-04, VIBRO-PEEN MARKING.
b Put an SB 72-0857 marking next to the existing TGB assembly part number on the TGB housing. Refer to the SPM, 70-16-04, VIBRO-PEEN MARKING.
(d) If the radial gearshaft is replaced because of a failed inspection, do as follows:
1 Put an SB 72-0857 marking next to the existing TGB assembly part number on the TGB housing. Refer to the SPM, 70-16-04, VIBRO-PEEN MARKING.
(5) Assemble the TGB assembly. Assembly instructions for the TGB assembly have not changed.
Refer to the GE90-100 EM, 72-62-00, ASSEMBLY 001.
(6) Send the paragraph 5., , Table 2, inspection results to GE Aviation ProductAPPENDIX - B Support Engineering (PSE) via the survey site.
