Sensitive systems

Sensitive systems are aircraft systems that may require certification, often by a specialized or certified technician, after maintenance has been performed. This certification may need to occur before the aircraft can be released. You can configure sensitivities on SYS class config slots.

By default, Maintenix supports the following sensitive system types:

  • Category III Instrument Landing System (CAT III)

  • Extended-range Twin-engine Operational Performance Standards (ETOPS)

  • Required Inspection Item (RII)

  • Fatigue Critical Baseline Structure (FCBS)

  • Reduced Vertical Separation Minimum (RVSM)

Note: You cannot add sensitivities to Tracked (TRK), Root (ROOT), or Sub-assembly (SUBASSY) config slots.

The History tab for the config slot records events associated with sensitivities. For example, when a user changes a sensitivity type on a config slot, or a user applies a sensitivity from a parent to a child config slot, the History tab displays this information.

Maintenance technicians will see warnings when working with faults that have associated sensitivities. For example, if a technician is raising an open fault on a CAT III sensitive system, Maintenix will display a warning indicating that the aircraft may require re-certification or, depending on your organization, some other special instructions.

Maintenix displays these warnings during the following workflows:

  • Raise open logbook fault

  • Log fault and close

  • Log fault and defer

  • Log fault and request part immediately
