Narrative:
A Bell 206L-3, registered JA6055, took off from a temporary helipad in Numata City, Gunma Prefecture around 09:38 for transmission line inspection, and contacted one of transmission lines that intersects the subject transmission line and crashed into a nearby field around 09:53.
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."
