Oil Storage SystemA. Oil Tank
(1) The oil tank is located on the fan case at approximately the 8:30 position.
(a) The tank is made of aluminum with a formed heat shield that protects the fan case assembly from the hot oil. The heat shield is held on by four straps and also gives fire protection to the oil tank assembly.
1 The heat shield is not a line replaceable unit.
(b) The oil tank has a swirl-type deaerator as part of the oil tank assembly. The deaerator is used to isolate air from the returning scavenge oil. The deaerator sends the air into the oil tank and then the tank releases the air through a pressurization valve (internal to the tank) to the gearbox. The pressurization valve keeps the tank at a minimum pressure of 12 psi (0.83 bar) to help push the oil from the tank to the lubrication and scavenge oil pump.
(c) The oil tank servicing is done through the oil tank cap. To close the lock, turn the cap handle 45 degrees clockwise to the CLOSE position and press down on the handle.
(d) To release the lock feature, lift the handle and turn it 45 degrees counterclockwise to the OPEN position.
(e) The cap handle has a pointer which indicates if the cap is in the open or closed position.
(f) A flapper valve in the manual gravity fill opening is used to stop a large quantity of oil loss if the cap is not correctly installed.
(g) The scupper drain is used to drain oil spills overboard through the drain mast. The drain plug is on the bottom of the tank.
(2) Oil tank sight gauge
(a) The sight gauge gives a visual indication of the oil level.
(b) The sight gauge is a line replaceable unit.
(3) Oil quantity sensor
(a) The oil quantity sensor is on the top of the oil tank. The sensor is used for flight deck indication of the quantity of the oil in the tank.
(b) The oil quantity sensor is a line replaceable unit.
