What happened
During an approach to land on the calm surface of Whitewater Lake, a single engine airplane encountered difficulties while attempting to touch down on the glassy water. As the aircraft made contact with the surface, it overturned and subsequently sank into the lake.
While the pilot managed to exit the wreckage without sustaining any injuries, the accident resulted in the deaths of all five passengers, who drowned following the submersion of the plane.
Findings
Investigations into the accident determined that the crash was caused by an improper level off during the landing sequence. The pilot failed to utilize the aircraft's flaps correctly, maintaining a full down position during the short final phase of the flight.
