## Discrepancy

AIRCRAFT WAS NOT GROUNDED: OVERWING EMERGENCY DOOR SHOW OPEN R3 DOOR ERRONEOUS INDICATION.  MAINTENANCE ACCOMPLISHED AN EMERGENCY OPERATIONAL CHECK OF THE 3R EMERGENCY EXIT DOOR INCATION PER AMM 52-73-00 AND FOUND NO ISSUES WITH THE DOOR INDICATION. MAINTENANCE WAS UNABLE TO IDENTIFY A SPECIFIC PART THAT WOULD HAVE CAUSED THE ORIGINAL ISSUE.
