8 Maintenance and Inspection Activity Variance andDeviation Control

There are two methods for controlling 9ariance and Deviation ctivities( one beingapplied to non-%+#Bs and the other to %+#Bs. Non-%+#Bs are recorded and controlled

using the 8 Notification and %+#Bs through the )acilities %tatus eport ,)%. The 8is an integral function of the +$$%( whereas the )% is an e?ternal . This is the date planned in +$$% for the

wor' to be underta'en.

3 2 Compliance Category

The compliance category is obtained from a data base which lists the tas' listsB and the

deviation band allowed. The deviation bands will be reviewed and approved by the+orporate Discipline )ocal !oint ,+D)! at least every two years. The compliancecategory is used to develop the tolerance periodB.

3 3 Planning

The +$$% can produce loo'-aheadB plans for two years and ;0 days which the =!planner will use to minimise deferment and optimise resources.

This is outside of )% and is reliant on close inspection and monitoring to ensure thatall required measures identified to reduce the ris' of an incident are implemented.

%eview and Approval

Documentation to bac' up the deviation can be attached and sent via a wor' flowB to
