## Discrepancy

(CAN) AIRCRAFT HAS RECEIVED A REPORT WHICH WE FEEL IS A REPORTABLE EVENT. THE CABIN ALTITUDE STARTED TO FLUCTUATE ERRACTICALLY AND BEGAN CLIMBING UNCONTROLLABLY. THE O2 MASK DROPPED AND COMMENCED EMERGENCY DESCENT TO MINIMUM SAFE ALTITUDE. THE LANDING WAS UNEVENTFUL AND ALL PASSENGERS WERE DEPLANED AT THE GATE WITHOUT FURTHER EVENT.
