Russian investigators are considering the crew's error, pre-flight technical faults and technical failures during the flight as the main three versions for the crash of a Dagestan-bound plane at Moscow's Domodedovo airport, an investigation source said on Sunday.
All three engines of the Dagestan Airlines' Tupolev-154 plane successively failed several minutes after it took off from Moscow's Vnukovo Airport for Dagestan's capital, Makhachkala, on Saturday afternoon. Two people were killed and about 80 were injured during the emergency landing as the plane skidded off the runway and broke into pieces.
"Investigators have seized pre-flight documentation and other materials on the pre-flight preparation of the Tu-154 plane. A preliminary study suggests that the crew took a decision to fly with two technical faults aboard the plane," the source said.
