SYNOPSIS
Shortly after departure from Dublin Airport (EIDW), the Flight Crew noticed fumes and smoke entering the cockpit. Fumes and smoke were also reported in the passenger cabin. The Flight Crew donned their oxygen masks and smoke goggles and carried out the appropriate emergency checklist actions. The aircraft returned to EIDW and landed safely, by which time the smoke had dissipated. The aircraft taxied to its parking stand and the passengers and crew disembarked normally.
Subsequent examination of the No. 4 engine found a leak in an oil supply pipe, which is likely to have caused oil contamination of the bleed air supply used for air conditioning.
