Widely circulated YouTube conversation between Kathmandu Air Traffic Control and the US-Bangla flight that crashed on March 12 was partly similar to the original conversation the investigators examined Wednesday, said an official in Dhaka closely monitoring the Nepal-led investigation
The official declined to disclose the duration of the original conversation and the differences between original and circulated conversations.
‘Timing of the original conversation will be correlated with the flight data recorder and cockpit voice recorder and many other things to determine the actual cause of the crash,’ said the official.
Few hours after the Canadian manufactured Dash-8 Q400 aircraft of Bangladesh operator US-Bangla Airlines crashed at Tribhuvan International Airport on March 12 killing 45 of the 67 passengers and all the four crews, a reported conversation went viral on YouTube, viewed nearly four lakh times in the past week.
Associated Press reported from Kathmandu that the recording of the conversations between the pilot and air traffic controllers indicated confusion over which direction the plane should have landed.
‘We are analysing the conversation, and would go for analysing many things in accordance with the Annex 13 of ICAO,’ Bangladesh Aircraft Accident Investigation Group head Captain Salahuddin Md Rahmatullah told New Age over phone from Kathmandu Wednesday evening.
Salahuddin is representing Bangladesh in the investigation.
A civil aviation official said, ‘The authorities were planning to send the black box of the crashed plane to Canada for an independent examination instead of doing it by the Canadian manufacturer.’
According to the Annex 13 of International Civil Aviation Organisation rules, the state of registry, the state of the operator, the state of design and the state of manufacture are entitled to appoint an accredited representative each in the investigation.
Black box is made up of two devises – flight data recorder and cockpit voice recorder, which give an accurate testimony, narrating the aircraft’s flight history, to assist any investigation, the aviation accident investigators said.
The official, however, said that the primary report would be completed within a month of accident but the full investigation report would be completed
within a year as the investigation rules prescribed in Annex 13.
