## Discrepancy

MAIN CABIN DOOR WOULD NOT OPEN FOR APPROXIMATELY 3 MINUTES DUE TO ACOUSTIC SEAL NOT DEFLATING.  WE WERE ABLE TO OPEN THE DOOR USING MORE FORCE THEN TYPICALLY NEEDED TO DEPLANE PAX.  SIGN OFF.  INSPECTED/CHECKED CABIN DOOR SEAL AND VALVE OPERATIONS, NO DEFECTS NOTED.  PURGED DOOR SEAL BY INFLATION/DEFLATION OF DOOR SEAL WITH DRY NITROGEN SEVERAL TIMES.  RAN APU & ENGINES TO PERFORM ADDITIONAL PURGES AND OPERATIONS CHECKS ON CABIN DOOR SEAL.  RAN ENTRY DOOR SEAL THROUGH SEVERAL MORE CYCLES.  OPERATIONS CHECKS GOOD.  MX IAW CE560XLS MM52-10-04.
