What happened
On the morning of August 7, 2016, an Airbus A320-214, registered as G-EZUP, was operating a scheduled commercial flight from London Gatwick to Bastia. While flying under Instrument Flight Rules (IFR) over French airspace, the flight crew identified a technical issue involving a bleed air leak located on the left wing of the aircraft.
Due to the nature of the leak and the need for maintenance intervention, the crew decided to divert the flight. The aircraft subsequently landed at Geneva Airport at approximately 08:30 local time.
The investigation
The Swiss Transportation Safety Investigation Board (SUST) opened an investigation into the occurrence. The preliminary information focuses on the technical failure identified during the flight and the subsequent diversion to a suitable airport for repairs.
