The Procedure

The steps ChatterFix schedules for this PM. Every step is a checkable item on the work order — a technician can speak their way through it without touching a keyboard.

  1. Confirm source, detector and borescope calibration dates
  2. Verify radiation enclosure lights and door interlocks on a cold test
  3. Check penetrant line materials are inside shelf life
  4. Confirm indications are archived against the article serial
  5. Remove an out-of-calibration instrument from the cell

Why This PM Exists

An NDT indication is evidence only while the instrument is in calibration and the enclosure interlock was actually in force. Past that date the image is a picture, not a disposition.

What Skipping It Looks Like

The cell keeps shooting because the schedule is full. Dosimetry and the door interlock are checked when an auditor asks, which is the wrong order.

Setting the interval

Monthly cold check. An out-of-calibration instrument leaves the cell. Source exposure is not part of this inspection.
