FAYETTE COUNTY, TN (WMC) - National Transportation Safety Board released the probable cause of the Pedi-Flite crash outside Somerville, TN that killed three first responders.
After a review of the helicopter's ground track, two obstacles were found in the immediate area, an 140-foot, unlit, non-functioning, cell tower and a 115-foot water tower.
According to the report, the helicopter's in-flight obstacle alert most likely warned the pilot to the obstacles. It goes on to say the pilot most likely initiated a climb, then lost control of the helicopter.
The NTSB released the following as the probable cause of the crash:
"The pilot's inadvertent encounter with night, instrument meteorological conditions while responding to an obstacle alert, resulting in an in-flight loss of helicopter control."
This accident happened on Oct. 22, 2013, in Fayette County; pediatric respiratory therapist Denise Adams, pediatric nurse Carrie Barlow, and pilot Charles Smith all died in the crash.
