Narrative:
AAIB investigation to Airbus A320-214, G-EZTK: Avionics fan failure causing vibration and fumes in the cockpit. In the cruise, between Paphos and Athens, 20 January 2017. Although the incident took place in Greek airspace, the incident was deemed serious enough to warrant an AAIB Investigation, (as the aircraft was UK-registered) and the following is the summary from the AAIB Report.

"The aircraft was on a scheduled flight from Paphos to London Gatwick. It was approximately 1.5 hours into the flight, cruising at FL340, when there was a sudden “whirring” noise and vibration emanating from the beneath the cockpit and forward galley area. The cabin crew were also aware of the noise. Approximately one minute later, the flight crew noticed a distinct electrical burning smell in the cockpit and this was confirmed by the SCC (Senior Cabrin Crew) member.

The decision was made to divert to Athens and the commander and co-pilot donned oxygen masks and declared a PAN. They then initiated a descent and diversion with clearance from ATC. The passengers were informed of the situation and the crew’s intentions over the passenger address. During the descent the crew consulted the Quick Reference Handbook (QRH) smoke and fumes checklist and initial actions were carried out.

In the absence of other indications or Electronic Centralised Aircraft Monitor (ECAM) cautions, the crew decided not to put the aircraft into an emergency electrical configuration. The aircraft landed at Athens without further incident, although it was 1.5 tonnes overweight at 67.5 tonnes. There were no injuries to the passengers or crew and a normal disembarkation was carried out.

=Nature of Damage to airframe=
