A310
Aircraft Equipment Problem Critical
Flight Crew Diverted; Flight Crew Landed As Precaution; General Declared Emergency
Aircraft
Approaching level off altitude of FL350; we got an ECAM advisory of low oil on the Number 1 Engine. All other parameters were fine so after level off we retarded the throttle per the QRH to see if that would affect the quantity. It remained low (less than 2 quarts) but the other parameters still showed normal. We sent a quick message to Dispatch to see if Maintenance had any thoughts; but before they could respond; we saw a slight fluctuation in oil pressure. ZZZ was about 100 miles in front of us so I decided to divert. I declared an emergency and sent Dispatch a quick message that we were going to ZZZ. Engine parameters remained in the normal range and there were no ECAM alerts; so we kept the engine at idle for the arrival. I took over as pilot flying 40 miles out and we made a flaps 20 landing. On rollout we got the Engine 1 low oil red ECAM; so we shut the engine down after we exited the runway. We taxied to the ramp with no other problems. The loss of engine oil caused us to divert and I declared an emergency because of the possibility of an engine shut down.
A310 Captain experiences low engine oil quantity upon reaching FL350 with all other parameters normal. When oil pressure fluctuation is noted the decision to divert is made and an emergency is declared. With good oil pressure the engine is operated throughout the approach and landing. During roll out the oil pressure light illuminates and the engine is shut down.
