Investigating agency: NTSB
Narrative:
The pilot reported that he and pilot-rated passenger assessed the weather conditions before departing on the local night flight, and determined it was safe to fly. The pilot estimated the visibility to be 5 miles. Shortly after takeoff, both the pilot and pilot rated passenger lost sight of the ground and horizon. The pilot wrote, "I felt the passenger/pilot grab the [control] yoke. I asked what he was doing. He said he felt we were turning. I then noticed we were going down." The pilot-rated passenger said they were "disoriented. [The pilot] thought we should descend a little. That's what we were doing when we hit the lake. We didn't really see it coming." He made no mention of control interference. Neither pilot was instrument rated. The airplane impacted a frozen lake, skidded about 300 feet, and fell through the ice. A witness reported that the visibility was 2 miles in fog.
Probable Cause: Improper weather evaluation by both the pilot and pilot/passenger, and the pilot's inadvertent VFR flight into IMC resulting in his spatial disorientation. Factors were the pilot rated passenger's spatial disorientation, fog, and night conditions.
