The families of the four people killed in a 2018 Guthrie County plane crash have filed lawsuits alleging that a maintenance error contributed to the crash.

Sources say that the lawsuits announced Thursday seek unspecified damages from Ultra Flight LLC., an aviation maintenance facility in Le Mars and its owner, Tomas Mullally. On November 9th, 2018 a Piper aircraft crashed about two miles south of the Guthrie County Regional Airport. The pilot, 49-year-old Edward Anderson of Le Mars allegedly suffered a heart attack and a student pilot attempted to make an emergency landing. Anderson and the three other passengers died from the crash: 36-year-old Patrick Kellen and 15-year-old Samantha Clark both from Le Mars, and 28-year-old Tyler Douvia of Merrill. The State Medical Examiner’s Office found that the victims suffered from multiple blunt force injuries in the setting of carbon monoxide toxicity.
