Jason Christiansen, 27, of Ellinwood fell at least 30 feet while trimming trees, and was flown to a Wichita hospital on Wednesday, the Barton County Sheriff’s Office reports.

The accident occurred around 10:45 p.m. as Solida Tree Service was trimming trees in the area of 614 East Barton County Road, when the boom on one of the trucks failed. Christiansen was in the boom lift when it broke away from the truck. He suffered a cut above the left eye, and was flown to Wichita by Eagle Med helicopter.

Upon investigation, it appeared that about half of the bolts holding the boom to the truck had failed due to rust, the BCSO reports. The truck was last inspected in December of 2011.

Ellinwood Ambulance and Kansas Highway Patrol also responded to the accident.

Information on Christiansen’s condition was unavailable on Thursday.
