A small plane crashed Tuesday in an Alabama field near the Marion County Airport leaving the pilot, the sole occupant, injured, authorities said.

The twin-engine Beechcraft D55 fixed wing aircraft crashed near the airport and Interstate 22 in Hamilton around 2:24 p.m., the Federal Aviation Administration and the Alabama Law Enforcement Agency said.

The pilot was conscious and alert when transported to a local hospital for treatment, Marion County Emergency Management Agency Director Eric Terrell said. The extent of the pilot’s injuries were not disclosed.

The plane took off from Memphis, Tennessee, but it was unclear where it was headed, authorities said.

The FAA said it was sending investigators to the scene, although the National Transportation Safety Board will lead the investigation into the crash.
