Sources at the airport said the recorded dialogue between ATC officials in Kolkata and the pilot of the Jet aircraft shows that the plane was facing problems with its equipment once it left Yangon ATC.

The pilot of the aircraft reportedly said the problem was probably caused due to a glitch in the equipment of the aircraft.

Meanwhile, the executive director of the airport, P K Singhal, told the Indian Express that the Directorate General of Civil Aviation (DGCA) has been asked to probe into the matter.

“We are involving the DGCA as the probe may include checking of the aircraft’s equipment to ascertain what went wrong. They will also be questioning the airline engineers,” said Singhal.

“The pilot has admitted to the ATC that there was a technical glitch in his air-borne equipment,” he said, adding he has also ordered a on the “action taken” during the half-an-hour crisis.

“In simple words, at any point of time, an aircraft is supposed to use one particular frequency. A certain channel discipline needs to be maintained at all times,” explained a senior ATC official, adding that there are six available frequencies for air-borne pilots to establish contact with the ATC.
