Spanish investigators have opened an inquiry after an Air Nostrum Bombardier CRJ200 alternately lost power in each engine while in flight, during a domestic service to Santander.
The aircraft had departed Madrid, with 44 occupants, at 17:13 on 24 February.
Spain's ministry of transport says that "some miles" before landing at Santander, the right-hand General Electric CF34 engine stopped, followed by the left-hand one.
"The incident occurred for about no more than two minutes in total, always at least with one engine working," says a spokesman for the ministry.
"The crew activated the emergency [procedures] and suddenly both engines worked at the same time."

Spanish air accident investigation agency CIAIAC says the incident occurred 55nm (102km) from Santander.
It has identified the aircraft as a CRJ200ER registered EC-IKZ, serial number 7732, which Flight's ACAS database lists as a six-year old leased airframe.
"The landing operation was totally successful," says the ministry spokesman.
He adds that CIAIAC has requested information from Bombardier and General Electric to support its inquiry.
