Synopsis

A319 flight crew reported receiving a Number 2 Engine low oil pressure ECAM warning during takeoff at 1;500 feet AGL. The flight crew ran the appropriate checklist and decided to return to the departure airport.

Narrative

Departed Runway XXL in ZZZ with First Officer as PF. At approximately 2;000 ft. AGL we got an ECAM for Eng 2 low oil pressure. Assigned pilot flying (FO). Approximately 5 seconds later the oil quantity on Eng 2 rapidly decreased towards zero. Informed ATC of the situation and requested an immediate return for RWXX. Turned crosswind and ran QRC and then ECAM actions. On downwind finished QRH procedures and landing performance landing. Informed FAs of the situation and to expect precautionary landing and normal taxi-in. Sent message to dispatch. Made PA to passengers. Normal/Overweight landing followed (146;000 lbs) smooth touchdown. Taxied in and parked at gate. Entered discrepancies in maintenance log. Maintenance opened the #2 Eng Cowl and found that the oil filter assembly had blown off the bottom of the engine; all four mounting bolts for the assembly stripped (the inserts pulled out of the aluminum casting).Cause: Mechanical Failure.Suggestions: Insure that threaded inserts used to install oil filter housing are reliable.

Second reporter narrative

I was the flying pilot on the flight. We were cleared takeoff on XXL; the takeoff and initial climb normal through 1;000 AGL. I requested AP 2 on. Climbing through approximately 3;500 MSL approaching ZZZZZ Intersection we got an ECAM Eng. 2 oil low pressure. I continued PF duties; the Captain called out the problem and identified that Eng. 2 oil quantity was dropping very quickly. We received RV from ATC back to RWY XX and told them of our Emergency. Captain ran the QRC; ECAM; QRH and performance numbers for an over weight landing. We shut down Eng. 2 per ECAM on our downwind leg at 5;000 ft. I requested to extend our downwind to give us time finish checklist; advise the company; flight attendants and passengers. We were given a climb to 6;000 ft. and started our turn to intercept the ILS to Rwy XX. The Approach and Precautionary landing was normal; we taxied to the gate. Maintenance initial inspection showed that Eng 2 oil filter had separated from the Engine. Suggestions: Determine why the oil filter separated from the engine.
