General

This TASK gives the procedure for the inspection of the pressure indicating tube (01-500). For the other pressure indicating tubes, refer to Inspection-000 TASK 36-21-49-200-100.

Fig/item numbers in parentheses in the procedure agree with those used in the IPC.

The TASK numbers of the practices and processes referred to in the procedure are in SPM.

All parts must be cleaned before they are examined, refer to Cleaning-000 TASK 36-21-49-100-100.

All parts must be visually examined for damage, corrosion and wear. Defects which are not identified in the procedure must be referred to IAE.

The policy which is necessary for inspection is given in SPM TASK 70-20-01-200-501.

The procedure for those parts which must have a crack test is given in Step. Do the test before the part is visually examined.

Before the parts are discarded make sure there are no repairs available. Refer to the instructions in the repair before a discarded part is used again or oversize parts are installed. Parts which should be discarded can be held although no repair is available. The repair of a discarded part could be shown to be necessary at a later date.
