FAA Decommissioning Notes
The power cord on this unit was intentionally cut by FAA technical operations personnel as part of their
standard decommissioning procedure. This is a common federal practice used to:
- Prevent the unit from being energized after retirement
- Ensure it cannot be returned to operational aviation service
- Visually signal that the equipment is officially removed from service
- Eliminate liability associated with outdated or uncalibrated test gear
For collectors, the cut cord is a desirable provenance indicator showing the unit came directly from FAA service
and has not been modified or revived after retirement.
