Common Information

TASK 72-00-00-200-000 Engine General - Examine The Modular/Non-modular Interfaces, Magnetic Chip Detectors, And Borescope Examine The Engine, Inspection-000

General

The modular/non-modular interfaces must be examined before the installation of a module or a non-modular part.

The interfaces must be examined to make sure their condition is satisfactory for continued use.

Each interface has been given an alpha identification. For example the LP compressor (fan) module and the LP compressor/intermediate case module has an interface identified as interface B. The module applicable is further identified by the module subject number as a suffix to the alpha.

Thus the rear face of the LP compressor (fan) module, (72-00-31), is identified as interface B-31.

To identify each interface, refer to Figure, Figure, Figure, Figure, Figure, Figure, Figure, Figure, Figure, Figure, Figure, Figure, Figure, Figure.

The procedure to examine each interface is given in the subsequent TASKs.
