The report is a little confusing as to throttle movements. First he reportedly closed the throttle then “managed to get the engine to ground idle” then he reportedly shut the engine shut down again. Hence my confusion.


From the report: “Meanwhile, as the helicopter advanced through the third 360º yaw to the left side, the pilot rolled the throttle closed. This action slowly stopped the yaw rate.

“The pilot then managed to get the helicopter to ground idle. He then shut down the engine and switched off all power. He then disembarked the helicopter while the rotor blades were still in motion just in case the helicopter started to yaw uncontrollably again.
