Officials say the aircraft did not crash, but was damaged when it made a hard landing. They say an estimated 60 gallons of fuel may have spilled onto the ground. A hazardous materials team is at the scene.
Authorities say the pilot and two passengers were not injured.
No further details were immediately available.
