Mid-air collision between Bell 206B JetRanger JA9101 and Aerospatiale AS 355F Ecureuil 2 JA9581. Both helicopters were filming a news item on a robbery.
Cause
It is presumed that the cause of this accident was that the pilot of JA9101 sighted JA9581 flying ahead only a few seconds before the collision and initiated immediate evasive action, but it was too late.
It is considered that this was contributed to by JA9101's pilot focusing on locating the news target, believing there were no other aircraft in the vicinity of the accident site, which led to a delayed sighting of JA9581.
