What was found
ON DESCENT THE CREW RECEIVED A HYDRAULIC QUANTITY LOW CAS MESSAGE AND THE AIRCRAFT LANDED WITHOUT INCIDENT. UPON A POST FLIGHT INSPECTION THE CREW NOTICED HYDRAULIC FLUID RESIDUE ON THE LOWER FUSELAGE AND FLUID LEAKING FROM UNDER THE BAGGAGE AREA. FURTHER INVESTIGATION REVEALED THAT A HYDRAULIC SYSTEM LOW PRESSURE SWITCH HAD FAILED AND FLUID WAS LEAKING OUT OF THE SWITCH THROUGH THE CANNON PLUG CONNECTION. THE SWITCH WAS REPLACED AND THE AIRCRAFT RETURNED TO SERVICE WITHOUT FURTHER INCIDENT.
