Initial discussions with the sole survivor of the Yakovlev Yak-42 crash at Yaroslavl have not revealed any immediate clues over the aircraft's failure to become airborne during its take-off run.
The flight engineer was the only one of the 45 occupants - including the city's ice-hockey squad - to survive the 7 September accident.
Russia's Interstate Aviation Committee (MAK), which is investigating the crash, has interviewed the engineer. He clarified that the senior hockey team personnel - including the coaches - were seated in the forward cabin, while the players were in the centre cabin.
The engineer also said most of the luggage was loaded into the rear of the aircraft, MAK added.
It said the interview with the engineer revealed no evidence of problems in the aircraft systems in the previous service, or during the ill-fated flight.
