## Discrepancy

AIRCRAFT WAS GROUNDED: DURING CRUISE A STRONG MUSTY, MOLDY SMELL FROM ROW 22 TO 29 WAS REPORTED. FLIGHT CREW ACCOMPLISHED QRH PROCEDURES AND SHUT CROSS BLEED ALONG WITH SHUTING OFF PACK 2 AND IT GOT WORSE. RESUMED STANDARD CONFIGURATION AND THE SEVERITY DECREASED. THE ODOR CONTINUED FOR THE REMAINDER OF THE FLIGHT. MAINTENANCE ISOALATED THE SOURCE OF THE ODOR TO THE #1 BLEED AIR PACK AND ACCOMPLISHED THE DECONTAMINATION OF THE ENVRONMENTAL SYSTEM COMPONENTS PER TASK CARD 26L00021004. A SATISFACTORY OPERATIONAL CHECK WAS ACCOMPLISHED WITH NO ODORS NOTED.
