## Discrepancy

(CAN) PILOTS REPORTED THAT WHILE CRUISING AT 23 000 FT THEY A HEARD CRACKLING SOUND.  SOON AFTER THEY DETECTED THIS SOUND, THE INTERIOR PANE OF THE LEFT  WINDSHIELD SHATTERED.  HEAT WAS NOT IN USE, AND THE AMBIENT TEMPERATURE WAS -30 C.  THE PILOTS IMMEDIATELY REDUCED PRESSURE AND DECENDED TO 10 000 FT, THEN RETURNED TO AMO FOR MAINTENANCE.
