Narrative:
Ex N22640, N712WC, JA9724, C-GIJQ. Written off (damaged beyond repair) 29 June 1999, when crashed near Yokosuka, Kanagawa Prefecture, Japan. During crop spraying, the helicopter was being flown at a low speed and low height across a paddy field. During this manoeuvre, the helicopter began an uncommanded yaw to the right. The pilot attempted an emergency landing, but the helicopter touched down hard, and rolled over near Yokosuka, Kanagawa Prefecture.

The accident was attributed to loss of tail rotor effectiveness in cross wind conditions. Registration JA9724 cancelled 15 December 1999
