NTSB Identification: WPR13FA095
14 CFR Part 91: General Aviation
Accident occurred Saturday, January 19, 2013 in Boulder, UT
Probable Cause Approval Date: 03/24/2014
Aircraft: CESSNA 140, registration: N2341N
Injuries: 2 Fatal.

NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.

A witness stated that he observed the airplane fly over his position near a state highway at an altitude he considered “low” and that the airplane’s engine sounded “loud.” Shortly after, he observed the airplane impact power lines that local power company personnel estimated to be about 100 feet above ground level. All major structural components of the airplane were located within close proximity to the collision location. A postaccident examination of the airframe and engine revealed no evidence of mechanical malfunctions or failures that would have precluded normal operation. Witness marks located on the right wing were consistent with damage from impact with the power lines. Local residents reported having witnessed the pilot flying at low altitudes on previous flights. Based on these reports, as well as the accident witness report, it is likely that the pilot was flying at a low altitude during the accident flight and failed to maintain clearance from the power lines.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The pilot’s improper decision to maneuver at a low altitude and failure to adequately monitor the environment to maintain clearance from power lines.
