## Discrepancy

PILOT REPORTED A LOSS OF NR INDICATION DURING FLIGHT. PILOT ELECTED TO MAKE A PRECAUTINARY LANDING. TECH WAS DISPATCHED BUT DUE TO THE LOCATION AND SECURITY OF THE ACFT,  ELECTED TO HAVE THE ACFT TRANSPORTED TO THE MX FACILITY FOR FURTHER TROUBLESHOOTING. THE TECH REMOVED THE NR SENSOR AND VERIFIED THAT THE OHM VALUE WAS NOT READING AS REQUIRED.
