5.0 Test Procedure

Use reference 2.1.1 and attached figures to locate components and sub-assemblies.

See Figure 4 for identification of the ISO latch datum aids.

Dimensions taken from ISO latch mounts are to be from the tip of the ISO latch datum aids.

5.1 Install the ISO latch datum aids into their respective bolt patterns (i.e. install the HPU datum aids into where the HPU ISO latch mounts, etc.)

5.2 Create/find a horizontal reference plane using the ISO latch datum aids SDC2, SDC4 and DC6.

5.3 Create a global centerline plane which runs through center of 4 inch block on aft fixture and midway between innermost alignment pins on forward fixture and is perpendicular to the horizontal reference plane.

5.4 Measure and record all dimensions in Table 1. Use Figure 1 through Figure 5 as a reference to where the specific dimensions are taken from. See notes below for information regarding the measurement of each dimension.
