From the Wikipedia article
The 2016 Japan Air Self-Defense Force Raytheon U-125 crash occurred on 6 April 2016. On that day, a Japan Air Self-Defense Force Raytheon U-125 that had taken off from Kanoya Air Base was flown into terrain during a check flight, killing all six occupants of the aircraft.

The aircraft, stationed at Iruma Air Base, had taken off on that day at 8:49 from Iruma for Kanoya, where it was to be used on a calibration flight. It arrived there at 12:06. The aircraft took off from Kanoya Air Base at 13:15. About 80 minutes later, when the aircraft was on approach to runway 08R in adverse weather conditions and about 10 kilometres north of the air base, radio contact was lost.
