## Discrepancy

THIS VALVE WAS WORKING PROPERLY WHEN REMOVED FOR SB 550-21-41.  FURTHER INSPECTION FOUND CRACK IN POPPET AREA.  IF IT HAD CRACKED MORE, IT IS POSSIBLE THAT THE CABIN WOULD HAVE DEPRESSURIZED.  SUBMITTER STATES IF THIS SB APPLIES TO AIRCRAFT, C/W AS SOON AS POSSIBLE OR HAVE FREQUENT INSPECTIONS UNTIL ACCOMPLISHMENT.  THIS IS ALSO AIRESEARCH BULLETIN 103576-21-4056.
