On 29 September 2017, the crew of an Airbus A320 detected a smell of burning plastic and simultaneously observed black smoke entering the flight deck near the right side rudder pedals. Completion of appropriate response procedures reduced the smoke and a diversion to Athens with a MAYDAY declared was without further event. The origin of the smoke and fumes was traced to the failure of the static inverter which was part of a batch which had been previously notified as faulty but not identified as such by the aircraft operator’s maintenance organisation which has since modified its relevant procedures.
Description
On 29 September 2017, an Airbus A320 (G-EZOC) being operated by easyJet on a scheduled international passenger flight from Mykonos to Milan Malpensa as EZY2952 was in the cruise at FL 360 in day VMC when smoke and fumes in the flight deck led to a MAYDAY declaration and a diversion to Athens which was accomplished without further event after both pilots had donned oxygen masks and completed the appropriate abnormal procedure. The 192 occupants disembarked normally and the only resulting damage to the aircraft was to part of a static inverter installed below the flight deck.
Investigation
An Investigation was carried out by the Hellenic Air Accident Investigation and Aviation Safety Board (AAIASB).
It was noted that the 38 year-old Captain had a total of over 5000 hours on type and held an ATPL (Airline Transport Pilot's Licence) issued in 2011 and that the First Officer had over 4000 hours on type and held an ATPL issued in 2014.
What Happened
It was established that when the fumes and smoke appeared, the latter appearing to emanate from the flight deck floor in the vicinity of the right side rudder pedals, the aircraft was level at FL360 and had already overflown Athens. Both pilots donned their oxygen masks and completed the corresponding QRH non normal procedure and then notified ATC of their wish to divert to Athens and declared an emergency which was completed without any further issues arising in flight or on the ground after landing.
