The doomed EgyptAir plane that crashed last week did not show technical problems prior to take off in Paris, Egyptian investigation sources said on Tuesday.
Egypt's state-owned newspaper Al-Ahram reported that the aircraft showed no technical difficulties before taking off, citing an Aircraft Technical Log signed by its pilot.
Al-Ahram published a scan of the technical log on its website.
The paper said EgyptAir flight transmitted 11 "electronic messages" on May 18 about three-and-a-half hours before disappearing from radar screens with 66 passengers and crew on board.
The first two messages indicated the engines were functional.
At 00.26GMT on May 19, the third message appeared and showed a rise in the temperature of the co-pilot's window.
The plane kept transmitting messages for the next three minutes before vanishing, Al-Ahram said.
