Meanwhile, the CEO of US-Bangla Airlines Imran Asif laid blame on Kathmandu s air traffic control, saying the controller "fumbled" the landing.
The plane in the Nepal crash has been identified as the Q400 turboprop, which is built in Toronto, and a Challenger business jet in the Iranian crash. "All of a sudden there was a blast and then another blast", she added.
The US-Bangla airlines plane had arrived in Kathmandu in the afternoon from the Bangladeshi capital Dhaka.
Meanwhile, while talking to an Nepal Army aircraft which is on hold about 10 km away, the ATC says that the Bangladesh aircraft is "on final for 20".
All 49 people on board were killed on February 12, 2009 when a Colgan Air flight from Newark Liberty International Airport to Buffalo Niagara International Airport, stalled and crashed into a house while preparing to land at the airport.
Nepali rescue workers gather around the debris of an airplane that crashed near the worldwide airport in Kathmandu on March 12, 2018.
The plane, a twin-propeller Bombardier Dash 8 flying from Bangladesh, swerved repeatedly before it crashed, landing near the runway and bursting into flames.
The officials, however, have said a technical glitch could be the cause of the accident.
The plane was reportedly carrying 67 passengers and four crew members.
"I saw the plane make a sharp turn over the terminal back towards south and then disappeared towards the runway".
The US-Bangla Airlines is a privately-owned Bangladeshi airline headquartered in Dhaka.
According to SSP Bishwaraj Pokharel, spokesperson at Kathmandu Metropolitan Police Range Office, 49 were confirmed dead in the crash.
Bombardier will investigate after planes built by the Montreal-based company crashed in Nepal on Monday and on Sunday in Iran, killing a total of about 60 people. In 1992, a Thai Airways flight from Bangkok crashed while trying to land in Kathmandu in 1992 killing all on board.
Nepal's poor air safety record is largely blamed on inadequate maintenance, inexperienced pilots and substandard management, and its planes are banned from flying in European airspace.
Even as the Bombardier aircraft is on approach, the Nepali pilots of other aircraft are heard warning the ATC that the US-Bangla pilot seems disoriented, according to the Nepali Times. The incident occurred during the landing but there were no injuries reported.
