On September 4, 2022, a DHC-3 Turbine Otter single-engine floatplane on a passenger flight from Friday Harbor to Renton, Washington, U.S., crashed into the waters of Mutiny Bay near Whidbey Island, killing all ten people on board.
[11] The dead include Washington civil rights activist Sandy Williams, founder and editor of Black Lens News,[12] as well as actress Megan Hilty's pregnant sister, brother-in-law, and nephew.
[14] A side-scan sonar was deployed by the University of Washington Applied Physics Laboratory and discovered large debris 190 feet (58 m) below the surface that were identified as being similar to the plane.
[19] On October 24, 2022, the NTSB released an update on its investigation, stating that the horizontal stabilizer actuator had separated into two pieces at a threaded assembly fitting, which could be a contributing factor to the crash.
[22] The following day, on October 26, 2022, the NTSB issued urgent safety recommendations to the FAA and Transport Canada urging all DHC-3 Otter operators to inspect the horizontal stabilizer actuator lock ring and report their findings to the respective agencies.
