FM Condition Histories (ECHs)

The Fabric Maintenance (FM) work (as defined in the Schedule) must be recorded in an Equipment Condition History (ECH).

Condition Histories are written for the Equipment IDs (that is why we call them ECH - Equipment Condition History). Once an ECH is written, it will be a permanent record that can be retrieved from either its active location or from a records archive or salvage location.

The ECH window is flexible enough to meet all needs for recording the significant events pertaining to any Equipment. ECHs can be divided into two types:

• Event or Opportunity Driven: This ECH is not linked to a Schedule, but an event is recorded, e.g. rerate performed, significant process change, a fork-lift dented the shell, etc. If no inspection data and codes are recorded either, this is referred to as a “Narrative Only” ECH.
• Schedule Driven: This ECH credits one or more Schedules and describes the work and/or findings associated with the credited Schedule(s).

The figure below explains in more detail the workflow between ECHs and Schedules: First a Schedule is created and Approved. Then the ECH is created and the Schedule is credited in the ECH. After the inspection has taken place, the findings are recorded in the ECH codes (checklists) and narrative. Then the ECH is Approved. As soon as the ECH is Approved the Credited Schedules will become inactive. In the case of recurring Inspection Schedules, new Schedules will automatically be created and Approved.

The ECH Condition Date will become the Last Inspection Date (LID). For recurring Inspection Schedules this is used to calculate the NID for the new Schedule (NID + User Interval). Remember that CAIRs are not recurring. 

The ECH as part of the FMA workflow.

The ECH lifecycle steps can be summarized as follows:

• Step A: Create an ECH (this can happen from several places in the application).
• Step B: Enter a Condition Date, Responsible Inspector, short Description (e.g. Internal, External, TA), etc.
• Step C: Credit the Schedule(s) or Select “Event/Opportunity Driven“.
• Step D: Specify the Inspection data and codes (use the available checklists and add Observations, Attachments, Photos, and Locations). Use the Fabric Maintenance Checklist.

• Step E: Write a Narrative (description of actions performed, and conditions found).
• Step F: Create new Schedules / CAIRs if necessary. Note: For recurring Schedules a new Schedule is created automatically.
• Step G: Review the ECH (use the report).
• Step H: Final Approve the ECH (when Witnessing is activated, additional Supervision and Authority steps also come in here).
• Optional: Edit the new Schedules if necessary.
• Optional: If necessary, backout the ECH (e.g., when the Equipment ID is incorrect or when a Schedule was credited incorrectly).

Remember that it is possible to record your ECH offline in the field!
