Procedure
Clean the parts. Refer to TASK 72-41-12-100-000 (CLEANING-000).
Mask the areas adjacent to inspection locations with CoMat 02-005 ADHESIVE TAPE (MASKING). This will prevent glare during inspection from Fluorescent Penetrant which may have soaked into the ceramic.
Do the crack test. Refer to the SPM TASK 70-23-04-230-501. While completing the Fluorescent Penetrant Inspection called out by the TASK, special attention must be given to the focused areas listed in the following locations:
SUBTASK 72-41-12-230-079 Focus Inspect the Rear HPC Disc for Cracks
NOTE
This SUBTASK is an additional examination to the Ultra High Sensitivity Fluorescent Penetrant Inspection of the whole component. The additional examination using Ultra High Sensitivity Fluorescent Penetrant is only required for component areas that are specified within this SUBTASK.
