The plane was carrying two others at the time of the crash — 56-year-old pilot Scott Johannes of Wasilla and another passenger.

Troopers say Johannes was flying the aircraft with the two passengers when he attempted to land in the bay, but crashed into the water. He and the surviving passenger were able to escape.

Four nearby vessels, two Coast Guard boats and several good Samaritans responded to the scene of the crash. Johannes and the surviving passenger were airlifted by the Alaska Air National Guard to Providence Alaska Medical Center in Anchorage.

Troopers say Resinger's family has been notified of his death. The National Transportation Safety Board and the Federal Aviation Administration have also been notified.

The investigation into the crash is ongoing.
