GUTHRIE CENTER, Iowa (KTIV) – Federal investigators have released their preliminary report into the Nov. 9 plane crash in central Iowa that claimed the lives of four Siouxlanders.
Indications are that carbon monoxide poisoning led to the crash.
The National Transportation Safety Board says a 2-inch-long crack in an engine muffler allowed exhaust to get into the cabin heating system.
Autopsies by the Iowa State Medical Examiner’s office revealed everyone on board had suffered from carbon monoxide poisoning.
Killed in the crash were the pilot, 49-year-old Edward Anderson, 36-year-old Pat Kellen and 15-year-old Samantha Clark, all of Le Mars, and 28-year-old Tyler Douvia of Merrill.
The plane was on its way from Le Mars to Osceola on a hunting trip. A student pilot who was a passenger on board radioed in that he thought the pilot had suffered a heart attack and he was going to divert the plane to the Perry Municipal Airport. The student pilot later radioed that he was going to try to land at the Guthrie Center Airport instead. The aircraft never arrived.
The next morning, the plane was found crashed in a farm pasture two miles south of the Guthrie Center Airport.
The NTSB says the student pilot did have a fair amount of flying experience. He co-owned the airplane with another person and had flown the plane solo on multiple occasions.
