Unsafe Condition
In-flight loss of a cabin sliding door, which had been locked in the fully opened position, due to the forward upper roller being out of its guide rail. The door edge exposed to the slipstream caused the forward lower roller train to be driven out of the guide rail due to aerodynamic loads, leading to door aft hinges failure and subsequent door departure from the aircraft.

Required Actions
Adjust the cabin sliding door to ensure the roller is completely inside the rail with a minimum clearance of 3 mm from the aft end of the rail. This involves loosening screws and stop, opening and pushing the door aft, moving the door forward to bring the roller into contact with the locking pin, moving the stop as far forward as possible, marking the stop location, unlocking and moving the door forward to access screws, securing the stop and screws at the marked location, ensuring the pin locking mechanism locks the door in the open position, and bringing the roller into contact with the stop of the rail. If the roller is less than 3 mm from the aft end of the rail, repeat the steps until the minimum clearance is achieved.
