## Discrepancy

AFTER PULLING & RESETTING CB L15, L16, C6 & T18, CREW REPORTED A PRONOUNCED BURNING PLASTIC SMELL WAS EVIDENT ON THE FLIGHT DECK.  THE SMELL CONTINUES TO LINGER 15 PLUS MINUTES AFTER FIRST NOTICED.  ACCOMPLISHED TSM 05-50-00-810-831-A & FOUND SOURCE OF ODOR COMING FROM APU BLEED.  ACFT WAS RELEASED ON MEL 49-10-01A.  RAN APU FOR APPROX 3 HOURS IN BLEED MODE & RAN BOTH PACKS IN COOL & HOT.  NO SMELLS NOTED AT THIS TIME.  THIS CLEARS MEL 49-10-01A.
