Narrative:
A motor glider was trapped by a grassy flood plain along Yahagi river while takeoff, and sustained damages on the left wing and the propeller. No personal injuries were reported. The glider was on a flight from Kohnan aerodrome (RJBK) to Ibaraki prefecture, and the accident was happen just after a temporal landing for refueling.

PROBABLE CAUSES
In this accident, when the Aircraft tried to take off, it is highly probable that it was not able to accelerate enough within the riverbed length, plunged into tall grass area before airborne, therefore its left main wing and left outrigger were entangled with tall grass, and veered to the left and fell down from the riverbed, which resulted in the damage to the main wings and propellers.
Concerning the reason why the Aircraft did not accelarate within riverbed length, it is somewhat likely that it might involve the following facts; the wet ground created a big drag, the wings were wet by rain and reduced lift, and the weight exceeded the maximum take off weight.
