CRYSTAL RIVER, Fla. (AP) - The pilot and co-pilot are OK after a Citrus County Sheriff's helicopter made a hard landing on U.S. 19 in Crystal River.

Deputies say the helicopter's engine malfunctioned just before 11 p.m. Tuesday while it was on routine patrol in Citrus County.

The 1968 OH-6 helicopter landed about a half mile south of the airport.

Officials say the pilot was treated at the scene. The co-pilot was not injured.

The sheriff's office will notify the Federal Aviation Administration of the incident.

No further details were immediately available.
