CANTON - Federal authorities are investigating the emergency landing of a medical helicopter.

The MedStat EMS Inc. helicopter was damaged while landing east of Canton Thursday night.

The pilot injured his back in the crash and was transported by a University of Mississippi Medical Center helicopter. The CEO of Winona-based MedStat says another of his company's helicopters picked up the original patient, who was en route to Baptist Medical Center in Jackson from Pioneer Community Hospital in Ackerman.

Two other crew members were taken to UMMC.

The Federal Aviation Administration is investigating.

MedStat operates helicopters based in Winona and near Columbus, its website says.
