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

The private pilot and passenger departed on a pleasure flight over the water; radar data showed that the airplane was at an altitude about 700 ft mean sea level. The passenger stated that she was concerned about how low the airplane was flying, but the pilot reassured her that they were fine and able to fly safely 200 ft above the water. The pilot then looked down at his tablet, which he was using for navigation, and the passenger saw him push the flight control yoke forward. The airplane descended and subsequently impacted the water and nosed over. The passenger was able to egress on her own as the airplane began to sink; however, the pilot appeared unconscious and did not exit the airplane. Neither the wreckage nor the pilot's remains were recovered. Although the wreckage could not be examined, the passenger reported no mechanical problems with the airplane before the impact. It is likely that, as the pilot was looking down at his tablet, he inadvertently pushed the control yoke forward, causing the airplane to descend into the water. Because of his distraction in using his tablet to navigate, he failed to detect the descent.
