The NTSB's narrative final · quoted from the NTSB record

The pilot waited on a gravel airstrip for a thunderstorm and associated rain to pass before attempting to takeoff. In a telephone interview the day after the accident, the pilot said that during the takeoff roll, the winds were calm, but during the initial climb, the airplane encountered a downdraft and descended, touching down on a sandbar in a river adjacent to the airstrip. The airplane started to climb again, but was forced down by another downdraft. The airplane touched down on another sandbar, and after a third attempt to climb, was forced down into the river, where it nosed over. In a subsequent written statement, the pilot wrote "in retrospect, it appears there was a mysterious loss of power." He further noted in his written statement "that two witnesses stated there was little or no wind, and that the airplane sounded like a normally powered takeoff, but the sound quickly dwindled, as if the throttle was pulled back to abort the takeoff."
