Rural/Metro crews responded to a report of a small plane that went down in the 5800 block of Martin Mill Pike in south Knox County around 6:00pm Thursday.
According to crews, the pilot was the only person in the plane.
The Knox County Sheriff's Office identified him as Quentin Elkins of Andersonville.
Investigators said he has a broken leg and some scrapes and bruises, but no life-threatening injuries.
He was transported to U.T. Medical Center for treatment.
The pilot told Knox County deputies that he lost power after taking off from Downtown Island Airport and tried to put the aircraft down in a field.
As it went down, the plane clipped some power lines. KUB responded to restore electricity to the homes that were without power.
No one on the ground was injured.
An FAA database shows the plane is a 1967 single-engine Beechcraft 35-C33a.
The plane is registered to Thomas Stubbs of Knoxville.
