The commercial pilot reported that the purpose of the flight was to position the helicopter and its installed camera equipment to the staging area of an intended aerial videography project. He added that the prestart, run-up, and hover checks were uneventful. While proceeding to the staging area, he climbed the helicopter to between about 800 and 1,000 ft above ground level. Shortly thereafter, the pilot lost consciousness, and his next recollection was waking up in an intensive care unit. After the pilot lost consciousness, the front seat passenger attempted to control the helicopter using the cyclic; however, the helicopter eventually collided with terrain.
According to medical records regarding the pilot’s postaccident hospital treatment, the pilot suffered a sudden, temporary loss of consciousness (known as a syncopal episode) while he was operating the helicopter. Postaccident medical evaluation led to a diagnosis of sick sinus syndrome, a heart condition, which likely caused the pilot’s loss of consciousness and his subsequent inability to maintain helicopter control.
Probable Cause: The pilot’s sudden incapacitation from a previously undiagnosed medical condition while in cruise flight, which resulted in his inability to maintain helicopter control.
