DENVER — A National Transportation Safety Board investigation has determined that pilot error likely caused a plane crash that killed a Colorado family of four.

The Colorado Sun reported Wednesday that 47-year-old Jeff Makepeace was flying a single-engine plane with his family from Fort Collins to Moab, Utah.

The agency says he flew into weather conditions requiring the use of his airplane's instruments that he lacked experience in operating.

Investigators say he likely lost control of the aircraft after experiencing spatial disorientation.

Makepeace and his 45-year-old wife Jennifer, twin children and dog died in the September 2017 crash in the mountains near Glenwood Springs, about 157 miles west of Denver.

Makepeace's relatives say they don't believe he intentionally put his family in harm's way and note he was "stickler for safety."
