Maintenance Action Plans
This section describes the maintenance action plans (MAPs) for the SNC. MAPs exist for all of the SNC’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 3
. 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
Event Codes and Actions
on page 35 in order to
determine the appropriate MAP.
•
Work through the
Database Full MAP
