On board the aircraft were a pilot in command and a transmission line inspector.
Both sustained serious injuries. The aircraft sustained substantial damage, but no fire broke out.
PROBABLE CAUSE: "In this accident, it is considered highly probable that the Aircraft, during its transmission line inspection flight, contacted one of overhead intersecting transmission lines, leading to uncontrollable situation, subsequently crashing to the ground. With regard to the contact with another transmission line, it is considered probable that the PIC's continued advance without locating his present position under the insufficient communicative condition, and failure of spotting the transmission line in time served as contributing factors."
