CAPE ELIZABETH, Maine (NEWS CENTER) - The National Transportation Safety Board says engine failure was behind that deadly plane in June last year.
Dr. Louis Hanson took his Stinson 108 out for a flight on the morning of June 24th.
Shortly before noon, he radioed that his plane had lost all power and that he didn't have the momentum to reach the shore. The plane splashed into the ocean off Portland Head Light and sank about seventy feet.
The force of the impact and water temperatures were contributing factors in Hanson's death.
The plane's engine was made of parts that were 60 to 70 years old, although they had been serviced in the past five years and the plane passed inspection in 2011.
