SYNOPSIS
At the commencement of a scheduled passenger flight from Dublin (EIDW) to Munich, Germany (EDDM), the aircraft, an Airbus A319-112, began the pushback and engine start procedure from parking stand 306L at EIDW. The No. 2 engine failed to start and the aircraft was towed back onto stand. When the aircraft had returned to the stand, the Cabin Crew reported to the Flight Crew that there was smoke in the cabin. The aircraft Commander declared a ‘Mayday’ by radio to Air Traffic Control (ATC) and directed the Cabin Crew to prepare for an emergency evacuation. The Flight Crew commenced the aircraft checklist for emergency evacuation. Following completion of this checklist it was noted that the smoke had begun to dissipate from the cabin. Because of this the aircraft Commander elected to disembark the passengers normally via the airbridge. There were no injuries.
