Firefighters and other emergency personnel responded on Sunday to several semitrailers that caught fire after a small plane crashed into them near an airfield outside Fort Worth, the authorities said.

Robbie Hoy, a public information officer for the Tarrant County Sheriff’s Office, confirmed that a plane had crashed but provided no further details. He said the Federal Aviation Administration would be taking over the investigation.

The National Transportation Safety Board confirmed that it was investigating the crash of the plane, a Beech King Air C90. That model usually seats up to six people.

It was unknown what led up to the crash or if there were any injuries.

Lois Kinman, a representative for the airfield, Hicks Airfield, said that the plane was not based there. She said she did not have any additional information.

Eric Faulkner, a manager at Wing It Cafe by the airfield, said he had seen “a bunch of black smoke.”

Near the crash site, another witness, Lauren Anderson, a cashier at an animal feed store, said that she had seen a “giant black cloud of smoke” that seemed at least 100 feet wide.

“There was probably about a 20-, 30-minute window where it was just nonstop emergency vehicles,” she said.

Later, the smoke had cleared, Ms. Anderson said.

“Honestly, it just kind of looks like nothing even happened,” she added. “It’s like, a weird feeling, knowing something did.”
