A two-member team probing the helicopter crash in Sirohi district in Rajasthan visited the Air Traffic Control (ATC) office at Sardar Vallabhbhai Patel International Airport (SVPI-A) on Monday.
They collected some crucial evidences before leaving for Border Security Force's base in Gandhinagar from where the copter had taken off just before the crash.
The mishap took place on Friday when the helicopter crashed in the hilly terrain of Fatehpura village near Abu Road in Rajasthan in Sirohi district, killing all the four occupants, including the pilot.
The occupants of the helicopter were identified as Captain Bal (pilot), co-pilot Vivek Choudhary (deputy commandant, BSF), BSF's sub-inspector Sohan Lal and an engineer of Pawan Hans Helicopter SS Chopra.
The team led by Survita Saxena, deputy director, Air Safety, met ATC officials at the airport on Monday morning. Sources at the airport said Saxena collected some recordings of pilot's conversation with ATC officials before it crashed an hour later at around 3:20 pm.
"The ATC monitors all kinds of air navigation in the state and records the aircrafts movements. The team probed the record details in which pilots and ATC officials had a brief conversation before it took off. They also inquired about several other technical aspects of the helicopter before leaving for Gandhinagar," said sources.
Sources have attributed two reasons that might have caused the accident - either a sudden technical glitch - or the chopper might have hit a rocky terrain in Sirohi, further adding that, on the hilly terrain, the weather sometimes changes all of a sudden, which may have reduced the visibility resulting into the crash.
"The chopper was flying around above 1500 ft when it crashed and so we are assuming weather might be one of the factors," source added. BSF officials said the team collected technical information related to the ill-fated helicopter.
They said the team checked the log book entry made by the pilot and the status registered when the chopper took off. It was also said the copter had developed some technical glitch a couple of days prior to the mishap.
