The aviation authorities said they had recovered the flight data recorder from the charred wreckage of the plane, which burst into flames after crashing into a football field near Kathmandu airport on Monday, killing 49 people.
Chettri said most worldwide flights are directed to runway 02 but depending on wind conditions, flights are also requested to use 20.
The team will meet the survivors of the crash and also discuss the possible reasons for the accident with Nepali authorities, amid reports of confusion between the air traffic control and the pilot of the ill-fated plane.
"We thought the pilot was following the instruction from air-traffic control tower", Keshav said.
The tower then told the pilot his alignment was not correct, but received no reply, Chettri said.
The injured were receiving treatment at various hospitals in Nepal.
"We can not claim this definitely at the moment, but we are suspecting that Kathmandu ATC tower might have misled our pilots to land on the wrong runway", Imran Asif, CEO of US-Bangla Airlines, told reporters in Dhaka.
Witnesses have described how the plane carrying 71 people abruptly changed direction moments before it crashed. Hundreds more gathered on top of a hill, staring down at the wreckage. Mohammed Selim, the airline's manager in Kathmandu, said the plane had circled the airport twice as it awaited clearance to land. The crowded city sits in a valley in the Himalayan foothills.

"It was flying northwards and it was much too low", said Amanda Summers, a retired American residing in Kathmandu. She added: "All of a sudden there was a blast and then another blast".
Fire crews put out the flames quickly, perhaps within a minute, she said, though for a time clouds of thick, dark smoke rose into the sky above the city.
Meanwhile, the CEO of US-Bangla Airlines Imran Asif blamed Kathmandu's air traffic control, saying the controller "fumbled" the landing.

But experts say the Canadian-made Bombardier Dash 8 Q400 is a manoeuverable plane that was developed to fly in Canada's harsh arctic north and should be at home in Nepal's mountainous terrain.
Nepal Police Spokesperson DIG Manoj Neupane said 12 of the survivors have been admitted at Kathmandu Medical College Hospital, four at Norvic Hospital, three at Grande Hospital, one at Om Hospital, and one at Medicity. "Until then, any comment on the matter would be inappropriate and invalid", said Secretary Devkota. "We still have hope that there has been some mistake on the list, or he is in some other hospital". "Yes TIA is narrow and we are in need of new global airports but claims of infrastructure being the reason behind the crash is unfounded", said Gautam.
