In addition to the common task properties, the following options are used to configure corrective tasks in the Maintenance Task window:

If you have selected to perform a corrective task upon inspection and an inspection or preventive task does not occur after the failure, then the block will never be restored. This could happen under either of the following circumstances:

      • Neither an inspection nor a preventive task is specified for the block.

and/or

For corrective and preventive tasks, the simulation requests a crew as soon as a task is initiated; however, the crew does not begin performing the task unless/until the spare part is available.

The total time for the task consists of:

PLUS

OR

      • The time to obtain an available crew (based on crew availability) and any logistical delay time associated with the crew.

For example, if the block fails at 10 hours (on the system clock), the corrective task will take 5 hours, the time required to obtain the spare will be 48 hours and the logistical delay time associated with the crew is 8 hours, then:

If the spare part is available without delay and all other conditions are the same, then:
