Federal authorities are investigating after a small plane made an emergency landing on a Florida interstate Monday morning when its engine stopped during a training flight. The incident drew attention because the aircraft came down on an active highway rather than reaching an airport.

According to the initial report, the pilot managed to bring the plane onto the interstate while narrowly avoiding highway signs and vehicles. That kind of landing can be especially dangerous because of traffic, limited space and roadside structures.

The Federal Aviation Administration said it is looking into what happened. At this stage, the focus appears to be on the engine failure and the circumstances that forced the pilot to land on the roadway during the training flight.

Emergency landings involving small planes are relatively uncommon, but they often lead to detailed reviews of the aircraft, the flight conditions and the sequence of events before touchdown. More information is expected as investigators examine the plane and gather details from the flight.
