The captain takes the emergency checklist, and is looking for the procedure of an low oli press indicarion.

Accordingly they have to retard the thrust lever of that engine and they have to wait for about two minutes before they shut down the engine.

The pilot retatrdes the engine lever, and the engine starts to decelerate. The engine needs to cool down for about two minutes.

Mean while the crew contacts the traffic tower to inform them about the situation.

They know they can’t continue the flight on three engines, and they decided to return.

The captain informs the flight attendends on board and the passengers about the situation , and everbody is dissapointed about the return.

After following the emergency procedure engine number three will be shut down

and the pilot is contacting Air traffic controlabout their decision about returning.

usually above the sea.

When arrived at than point the crew starts t6o dump the nesseccary amount of fuel.

After the dump, the airplane is returning on it’s route and the crew are making preperations for the landing.

They have to remind, that een engine shutdown, has also consequences for the landing, because they are missing one reverser system, meaning a longer runway

Or they have to break longer and this usually costing hot brakes, or damage dtires.

The landing was going very well, and in the meantime the ground has been informed about the defected engine number three.

When the plane is arriving at the gate, maintenance is standing ready to take over the airplane, but they have to start a investigation about the trouble.

The airplane will be shifted out of route, en will be towed to the hangar.
