No Mayday call from pilot indicates a ‘serious controllability issue’
Aviation analyst Kyle Bailey has told Al Jazeera the lack of communication from the helicopter pilot or another flight crew member left no doubt that there was a “serious controllability issue”.
He said that if a helicopter has a serious technical issue mid-flight, the pilot’s first task is to “keep the plane flying, and then communications would be second”.
Bailey added: “We basically didn’t see any communication … because the pilot was probably just so focused on landing the helicopter or keeping it in the sky.”
The analyst also explained: “It appears from the helicopter being in two parts that the tail rotor most likely was sliced off, and that would be a result of the main rotor blade impacting the tail.”
He said this would have been caused by aerodynamic forces created when the pilot was manoeuvring to land the helicopter or possibly because of a technical issue.
Another possibility, he said, is tail rotor failure.
“If we see that spiral motion where the helicopters kind of rotating 360 degrees, clockwise or counterclockwise, that could indicate that the tail rotor failed, and … would be out of control”.
Bailey said adverse weather conditions and mountainous terrain could also have contributed to the fatal crash.
