Key Takeaways:

  • Multiple wrongful death lawsuits have been filed against Northwest Seaplanes (operator) and De Havilland Aircraft of Canada (manufacturer) following a fatal seaplane crash near Seattle last September that killed 10 people.
  • The lawsuits allege the accident was "entirely preventable" and seek damages, with plaintiffs including estates of several passengers.
  • A preliminary NTSB report found that a critical lock ring on the horizontal stabilizer actuator was missing, which could result in a loss of pitch control.
  • In response to these findings, the NTSB issued an urgent safety recommendation for all De Havilland Canada DHC-3 operators to immediately inspect the actuator lock ring.
