## Discrepancy

RT WING SLIDE DEPLOYED INADVERTENTLY.  SLIDE DOOR HAD 7 INCH HAIRLINE CRACK IN HONEYCOMB.  THERE ARE THREE INNER HINGES BROKEN AND FOUR KEEPERS RUPTURED.  *S/D*  THE SLIDE INADVERTENTLY DEPLOYED WHILE PINNING THE INFLATION CYLINDER.  THE DEPLOYMENT WAS HENCE OUT OF TYPICAL SEQUENCE.  THE COMPARTMENT DOOR WAS NOT COMMANDED TO OPEN.

THE ROOT CAUSE WAS HUMAN ERROR.
