Defer Fault
Explanation
Once the Maintenance Operations Controller (MOC) approves the deferral
reference from the Pending Reference Approvals page in
Maintenix, the line technician can defer the fault.
If the DEFER_ON_APPROVAL configuration parameter is set to TRUE in
Maintenix, the fault will be automatically deferred upon MOC's approval of
the deferral reference.
You can defer a fault on the
Task Details or My Work
pages.
To defer a fault click Defer Fault from the task or
fault details page and then click Record Deferral Details.
When you defer a fault, select a deferral reason and enter the deferral
action taken. You can also record a deferral note and proceed to sign off.
Depending on the Signature Service User Permissions for your user, you can
sign off using a digital signature or via an alternative sign-off process. You
can use an assigned YubiKey to sign off on the deferral creating an immutable digital signature.
To do so click
Sign, proceed with the sign off process, and click Finish. The
digital signature is stored against the task or fault and can be viewed at any
time.
Alternatively, if you are signing off without YubiKey authentication, simply click
Finish to complete the task.
Note: If you are deferring a fault and signing off using
a digital signature, follow through with recording the digital signature or
cancel the procedure before the final step to avoid canceling at the final
step and losing all task actions performed.
Prerequisites
- The fault status must be Open.
- Deferral reasons must be set up in Aviation
Maintenance/Basic Data/Fault.
- If you are using digital signature to sign off on the deferral, the application user should be registered with a valid
public certificate to use IFS signature service in Solution
Manager/Signature Service.
- If you are not using a digital signature to sign off, the E-Sign option
must have
been disabled from the Signature Service User Permissions
page.
System Effects
- The fault status changes to Deferred and the fault
is displayed with the list of deferred faults for the
aircraft turn.
- The deferral information on the fault is updated and an action is recorded
against the fault with the deferral action provided by you.
- The DEFER_ON_APPROVAL configuration parameter in Maintenix
must be set to FALSE.
- The task is unassigned from the work package and no longer displayed
as a work task.
- If the sign-off was handled using a digital signature, you can
download a .zip file containing digital signature information from the Attachments/Digital
Signatures tab at the bottom of the Task Details and Fault
Details pages.
Alternatively, if configured, you can view the digital signature files
at the external file storage location.
This .zip file contains .json, .xml, and
.pdf files. The metadata is stored in the .json and .xml files, while
the .pdf file includes the signed document containing the content
reviewed by the line technician.
The file name of the .zip file
follows the GUID.zip format, where GUID stands for
globally unique identifier.
The files within the ZIP file are
named in the following format: <Tail
number>_<Record ID>_<User ID>_<Timestamp>
- When deferring a fault that has a signed removal of a mandatory
component and there is no corresponding installation or signed
installation of a part for the same mandatory config slot and position
in the work package, you will see a warning indicating that the fault
removed a mandatory component and there is no matching part installation
in the work package.
- When deferring a fault, if the number of mandatory component
installations does not tally with the number of mandatory component
removals in the work package for the same config slot and position, you
will see a warning.
- If the fault you are deferring has part installation or removal
records, the information related to part changes are sent to CMS for
validation upon deferring the fault.
CMS warnings are displayed
on the following pages:
