The incident occurred on 11 February. According to preliminary data, the crew of the airliner sent an urgent signal Pan-Pan. 

Pan-Pan is the international standard urgency signal that someone aboard a boat, ship, aircraft, or other vehicle uses to declare that they have a situation that is urgent but, for the time being at least, does not pose an immediate danger to anyone's life or to the vessel itself.
