SNC 5100
Maintenance Action Plans
This section describes the Maintenance Action Plans (MAPs) for the SNC
5100. MAPs exist for all of the SNC 5100’s component systems.
If it is clear that a particular component system is at fault in a problem
situation, go directly to the MAP for that component by consulting Table 6.
If it is not clear which component system is at fault in a problem situation,
choose one of the following options:
• Work through the Event Codes and Actions in Table 7 on page 35 in order
to determine the appropriate MAP.
• Work through the “Start MAP” on page 42 in order to determine the
appropriate MAP.
