RIVERSIDE – (INT) - The National Transportation Safety Board will determine what caused a Riverside police helicopter to make a hard, tail-first landing at the city’s airport Friday.

One of two men on board was seriously injured at the climax to a training exercise, the FAA said.

The force of the impact broke off the tail rotor.

It wasn’t immediately clear whether the student or the instructor was piloting the Hughes MD500 D helicopter at the time of the incident.

The police department’s helicopter program is based at the Riverside Municipal Airport.
