## Discrepancy

(CAN) DURING EMERGENCY DECENT THE CAPTAIN USED THE OXYGEN MASK.  DURING THE REMOVAL OF THE MASK FROM THE STOWED POSITION, THE HARNESS INFLATION CENTRAL VALVE & OXYGEN SUPPLY CONTROL KNOB  SEPARATED FROM THE MASK.  THIS LEFT THE MASK HARNESS CONTINUALLY INFLATED REQUIRING THE PILOT TO HOLD THE MASK TO HIS FACE DURING USE.  RESOLUTION CAPT`S OXYGEN MASK REPLACED IAW AMM 35-10-10.  CHECKS SERVICEABLE.
