Synopsis

Air carrier flight attendants reported an inadvertent escape slide deployment after the crew had left the aircraft. Flight Attendants stated that all doors had been disarmed before leaving.

Narrative

ISD (Inadvertent Slide Deployment) at the 1R door; i was the FA C at doors 2R and 2L. Wasnt my door.. we arrived at the gate and did the all call as normal. called off doors 1 to 4. deplaned normally. there was no issue. I'm confident the doors were disarmed by the crew as procedure. Im fairly certain the 1R door was disarmed as i walked off the plane... the slide was not deployed while the crew was on. i cannot fathom how this happened. the crew followed monitor and challenge and performed the door report first thing as we arrived to the gate.

Second reporter narrative

Landed; seat belt sign was turned off. I turned lights to bright and said over the PA 'Flight Attendants Verify; Disarm Doors and Standby for All Call' Checked for movement of jetbridge then I proceeded to 1R. Did the Monitor and Challenge. Proceeded to 1L again did the Monitor and Challenge and then crosschecked. Did the ALL CALL. Agent knocked; I looked at both doors again and then gave the thumbs up at the 1L door window. After all the passengers had deplaned I did a walk through of the entire aircraft. To the best of my knowledge every door was disarmed. Suggestions: Taking a picture of the disarmed door and keeping it for a 48 Hr. period.
