It’s rare that investigators are unable to determine the cause of a plane crash.
But the National Transportation Safety Board says the crash that killed 3 members of a Harbor Springs family in 2016 is ‘unknown and undetermined.’
The pilot, Timothy Brown, his wife Tricia and their son Ted were killed in the crash of their twin-engine plane in Montana. Investigators say the weather was good, the plane had no problems, and they could detect no physical problems with the pilot.
