Cessna 525 Citation Jet, D-IPCS
The aircraft diverted to London Gatwick Airport after both FUEL FLTR BYPASS warning lights illuminated during the cruise, indicating that the fuel filters were obstructed. The aircraft landed without further incident. The investigation concluded that the obstruction was probably caused by ice forming on the fuel filters due to insufficient anti-icing additive being added to the fuel during the previous refuelling.
