KATHMANDU: The toll in Nepal's worst aviation disaster rose to 51 today with the death of two more passengers, as Bangladeshi experts joined the probe amid reports of an apparent confusion between the pilot and air traffic control over the runway.
The Dhaka to Kathmandu US-Bangla Airlines flight, with 67 passengers and four crew members on board, caught fire after it careened off the runway and ploughed into a football ground near the Tribhuvan International Airport yesterday.
The Nepal Home Ministry confirmed the death of 51 people in the crash the deadliest aviation accident in 25 years in Nepal, according to Himalayan Times.
Earlier today, hospital authorities confirmed the death of pilot Captain Abid Sultan.
His co-pilot First Officer Prithula Rashid was died yesterday, the report said.
Meanwhile, a Bangladeshi delegation today joined a six-member Nepali committee to probe the crash-landing.
The Bangla delegation includes Minister for Civil Aviation and Tourism A K M Shahjahan Kamal, Foreign Minister Abul Hassan Mahmood Ali and senior aviation officials, the report said.
The Bangladeshi airline and airport authorities in Kathmandu have blamed each other for the tragedy, after it emerged that there was confusion over landing instructions.
The last four minutes of the conversation between the pilot and Air Traffic Control at the airport indicates a possible confusion in the mind of the pilot about Runway 02 (the southern end) and Runway 20 (the northern end), a Nepalese newspaper reported.
The Nepali pilots of other aircraft are heard warning the ATC that the US-Bangla pilot seems disoriented, according to the Nepali Times.
At the very outset of the tape, the control tower was heard warning the pilot, "I say again, do not proceed towards Runway 20.
" And later, he is warned to remain on hold and not to land because there is another aircraft on approach.
After the plane apparently takes a right orbit, the ATC asks the pilot whether he wants to land on Runway 02 or 20.
The latter responds and says "We would like to land on 20"; he is cleared to land on that end of the runway, the report said.
The pilot was then asked if he has the runway in sight, to which he replies, 'Negative', it said.
He was asked to turn right, but immediately after that, the Flight 211 pilot says "Affirmative", that the runway is in sight.
The pilot then says, "Cleared to land Runaway 02", even though he had sought permission for 20.
However, ATC too now clears him to land on Runway 02.
Meanwhile, speaking to the Army 53 aircraft which is on hold about 10 kilometres away, the ATC says the Bangladesh aircraft is "on final for 20".
The last recorded words of the pilot are: "[Unintelligible] said sir, are we cleared to land?" After some silence, the clearly alarmed ATC controller shouts, "I say again, turn"!".
There is silence for a while, then a 'Fire One' calls the tower, indicating that a crash has occurred and the airport fire tender has been activated.
There were 33 Nepalese nationals on board flight UBG 211, a Bombardier Dash 8 Q400.
Others include 32 Bangladeshis, one Chinese and one Maldivian.
Bombardier is a twin-engine, medium-range and turboprop aircraft.
