Narrative:A Eurocopter AS 350B3 ditched in the East China Sea, 10 nm southeast of Agni Airport, or 40 km nothwest of Naha, Okinawa prefecture, Japan. The Écureuil took off from Naha at 15:12 LT to pick up (a) passenger(s) at Aguni. A distress signal was received by Japan Air Self-Defense Force at 15:28 LT. A search and rescue helicopter of Japan Air Self-Defense Force found the pilot and parts of wreckage at 15:50 LT. The sole pilot was rescued and sent to the hospital. The pilot states a pain on chest, however apparently had no major injuries.
PROBABLE CAUSES:
In this accident, it is probable that NR of the main rotor was reduced during the flight and flight altitude became unable to maintain, which led to ditching at the excessive speed and descent rate and caused damage to the airframe, followed by sinking.
It is somewhat likely that the reduced NR of the main rotor was caused by some kind of malfunction occurring with engine system; however, it could not be determined in which section of the engine malfunction occurred and what caused it.
