Incident Overview
During pre-taxi procedures, the number 2 (right) engine was operating and the captain had given clearance to ground marshals to remove the wheel chocks. The first officer had closed the cabin door and completed the passenger safety briefing. Following the briefing, the captain turned in his seat to demonstrate to the first officer how to secure a component of the cabin door to prevent it from "rattling" in-flight. At this time, the first officer was standing in the forward cabin.
Sequence of Events
While the flight crew's attention was focused on the cabin door demonstration, the airplane began to taxi forward. It subsequently rolled onto a curb and struck an airport security fence. The aircraft came to a stop after the impact.
Aftermath
No further details regarding injuries, damage, or aircraft specifics were provided in the initial report. The incident highlights a deviation from standard operating procedures during the pre-departure phase, where crew attention was diverted from monitoring the aircraft's movement.
