The pilot was able to put the plane down in a nearby field and walk away unhurt. The Goodyear Fire Department tweeted that he refused medical treatment.
"A single-engine Diamond DA 40 crashed under unknown circumstances shortly after departing from Runway 21 at Goodyear," Federal Aviation Administration spokesman Ian Gregor said in an email response to our inquiry.
The Goodyear Fire Department also tweeted that fuel was leaking from the downed plane, but said there was no fire.
It's possible that the plane clipped a power line as it went down, knocking out power to a few area residents.
Bruce Haffner was over the scene in the Penguin Air & Plumbing New Chopper. His video showed firefighters walking around the plane, which is registered to a flight school called CTC Aviation.
The FAA is en route to investigate the incident.
