The National Transportation Safety Board (NTSB) released 500 pages of findings on Friday into the September 2022 float plane crash off Whidbey Island that killed 10 people.
The single-engine float plane that crashed was a DHC-3 Turbine Otter, according to the NTSB. The plane was about 200 feet deep in the water after it crashed, according to South Whidbey Fire/EMS.
The NTSB’s investigation found that a specific clamp nut had unscrewed from the barrel of the plane, and that a circular wire ring designed to keep the nut in place was not present at all. In instances where the barrel and clamp nut aren’t secured, a plane loses the ability to control its horizontal stabilizer, as well as its control over its pitch (which affects the ability to point the nose of the plane up and down).
