CFIT usually implies forward airspeed with subsequent damage to the aircraft.
I would say CFIT implies they didn't plan on hitting the terrain/water. If it is planned then it is not CFIT. Low speed with armed floats and this could be CFIT just as it could be a planned ditching. We really know nothing.
This is no different than a large offshore oil company saying that the medevac we performed did not constitue a "lost time Injury" (LTI) because it was the end of his shift anyway.
