## Narrative

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

N900LC, A FALCON 900, WAS DESCENDING FROM ALTITUDE WHILE ON ARRIVAL TO KAGC AIRPORT.  WHILE CROSSING THROUGH APPROXIMATELY 15,000 FEET THE AIRCRAFT PENETRATED A CLOUD AND EXPERIENCED A BRIEF ENCOUNTER WITH MODERATE TO SEVERE TURBULENCE (AS DESCRIBED BY THE CREW).

THE SECOND IN COMMAND (SIC) WAS THE FLYING PILOT AND WAS USING THE AUTOPILOT DURING THE EVENT.  THE AUTO PILOT DID NOT DISSENGAGE DUE TO THE TURBULENCE AND REMAINED ENGAGED THROUGHOUT THE ARRIVAL TO THE AIRPORT.  A NORMAL VISUAL APPROACH AND LANDING OCCURRED.  THE CREW TRANSMITTED A NOTAM TO THE CENTER CONTROLLER REGARDING THE TURBULENCE.

DURING THE PERIOD OF TUBULENCE. ONE PASSENGER SUSTAINED A MINOR INJURY.  THE PASSENGER, AN 89 YEAR WOMAN, WAS IN THE LAVATORY AND RECEIVED A LACERATION ON HER ARM.  THE SECOND PASSENGER AND FLIGHT ATTENDANT WERE NOT INJURED.

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. For accidents, the NTSB's own investigation is the fuller record.
