## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

(-23) THE HELICOPTER MADE A HARD LANDING. A WITNESS REPORTED "I NOTICED A MED FLIGHT HELICOPTER APPROACHING THE AIRPORT FROM THE SOUTHEAST. THE BK 117 STARTED A FAST STEEP APPROACH FROM THE SOUTHEAST CORNER OF THE AIRPORT AND APPEARED TO BE SHOOTING HIS APPROACH TO OR NEAR THE MED FLIGHT RAMP. AS THE BK 117 GOT APPROX. 100 FT AGL, STILL ON A NW HEADING, IT STARTED TO FLARE TO SLOW THE DESCENT RATE. THE HELICOPTER CONTINUED TO DESCEND TO THE GROUND AND AS IT DID IT MADE A HARD RIGHT TURN TO AN EAST-SOUTHEAST HEADING, STRIKING THE GROUND (MAIN ROTOR BLADES & RIGHT SKID) COMING TO REST IN THE GRASS JUST OFF THE SOUTHEAST CORNER OF THE GUARD RAMP."
