The article below in English. (my translation). There's a video of it half way in the water in the link.
On 28th, off the coast of Ashizurimisaki of Kouchi prefecture, an accident occurred where an engine fell off of a JMSDF floatplane during training. There was a crew of 19 and 4 suffered light injury.
Before 3:00 in the afternoon on the 28th, off from Ashizurimisaki a JMSDF US2 floatplane that belonged to Air Station Iwakuni dropped one engine while it was training in takeoffs and landings over sea. The 19 crew members escaped by lifeboat and were then rescued by a nearby small size tanker. The 19 crew members suffered nothing life threatening but 4 suffered light injury such as bruises.
The US2 floatplane has the ability to take off and land in bad weather conditions with waves at around 3 meters in height. Up until now, there has been no accident before.
The JMSDF is creating an investigation committee to investigate the cause of the accident.
It's to be seen if this will hurt its deal potential with India and else where.
