a.
Maintainability. The IPADS design is easy to troubleshoot, identify, and replace the failed component.
Upon identification of the failed component and using the IPADS tool kit, figure 1-5, removal and
replacement can be accomplished within 10 minutes if PLL authorized. This allows the survey mission to
continue with minimal delay when the replacement components are on-hand. The CDU and BCU are
connected to the frame with clamshell type connectors allowing for easy removal and replacement.
Operator maintenance consists of cleaning and spot painting, CDU and BCU replacement, cables, and
mounting hardware replacement. The CPNU will not be removed from the IPADS frame.
b. Each component of IPADS that is to be removed is easily removed.
If the CPNU is not working it will not be removed from the IPADS frame. The entire IPADS is to be sent in for
repair.
