## Discrepancy

COMM 1 FAILED WITH VERY DISTINCTIVE ELECTRICAL ODOR IN FLIGHT. EVERY TIME YOU PUSHED TO TALK A YELLOW X WOULD APPEAR OVER COMM 1 IN BOTH GTCS ALONG WITH ELECTRICAL  BURN SMELL. IT APPEARED THE SMELL ONLY HAPPENED WHEN YOU PRESSED PTT COMM 1.  COMM 2 WORKED NORMALLY. WE WERE ON APPROACH WHEN FAILURE OCCURRED SO WE LANDED IMMEDIATELY.  C0MPUE) WIT1T OPS CHECK AND VERIFIED YELLOW X ON COM 1. REMOVED MFD AND GIA1 ANO COULD SMELL THE BURNT SMELL. ON GIA. REMOVED AND REPLACED GIA 1 PER PHENOM 300 AMM 31-41·05. OPS CHECK GOOD AT THIS TIME. NO NORE ELECTIUCAL BURN SMELL. PRESENT AT THIS TIME.
