PM History & Reliability Trend Log (per Asset)

The PM History & Reliability Trend Log keeps a chronological maintenance history for every asset — one row per event, tagged PM, failure, or repair, with labor hours, parts cost, downtime hours, and notes. Filter the timeline to a single Asset ID, then roll the whole log into a reliability trend and a cost-per-asset view that computes against the As-of date on your Settings sheet. It reuses the MN-03 Asset ID / Name schema and accepts close-out rows pasted from MN-08 and MN-10. Every figure is your own: the workbook holds no reliability averages, no downtime benchmarks, and no MTBF industry numbers — only what you log.
