I received a coordination message from [an adjacent center] for Aircraft X at FL290. Later I received an air to ground message that the aircraft was 'leaving' FL270 for FL200. The aircraft was still in [the adjacent center's] airspace and I was not in communication with the flight; but I was expecting a re-coordination from the sector or that it was a possible typo. This message comes into our error queue and when the aircraft is outside our airspace we don't process those messages. Aircraft X crosses into [our] Flight Information Region (FIR) and fails to make his position report within the allotted 10 minutes. I sent a request to [oceanic] to contact the aircraft as he was HF equipped only to make a position report. While I was waiting for [oceanic] to come back with a report; [the adjacent center] advised that they were not in contact with the flight and didn't have a position report either. When [oceanic] managed to contact the aircraft he reported that he was in fact at FL200; that he was down to one engine and couldn't maintain any higher altitude. I verified that he was [requesting priority handling] and got the requisite information and passed it to the Supervisor. The aircraft had elected to continue on to his original destination. He was still over an hour away from the airport when I was relieved of duty.
Center Controller reported an aircraft was late in reporting position and could not be contacted. The aircraft was eventually contacted and confirmed to be at a lower altitude due to an engine failure.
