## Narrative

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

AT 0657L, 7 SEP 2010, N331N, A 1990 LEAR 31 OPERATED BY AIR SERVICES, INC., DEPARTED IN VMC (VISUAL METEOROLOGICAL CONDITION) FROM RUNWAY 18 ON A PART 91 TRIP FROM KTVC (CHERRY CAPITAL AIRPORT, TRAVERSE CITY, MI) TO KPLN (PELLSTON REGIONAL AIRPORT, PELLSTON, MI).  THERE WERE 2 PILOTS AND NO PASSENGERS ON BOARD. APPROXIMATELY 4 MINUTES AFTER TAKEOFF, THE PILOT EXPERIENCED UNCOMMANDED LEFT AND RIGHT RUDDER PEDAL MOVEMENT AND ASSOCIATED AIRCRAFT YAWING CONSISTENT WITH THE ALTERNATING RUDDER PEDAL MOVEMENTS.  THE PILOT EXECUTED MEMORY ITEM ACTIONS BY PRESSING AND HOLDING THE CONTROL WHEEL MASTER SWITCH.  INITIALLY, THE RUDDER PEDAL MOVEMENT AND YAWING STOPPED, BUT SEVERAL SECONDS LATER, THE RUDDER PEDAL MOVEMENT AND YAWING OCCURRED AGAIN.  AN EMERGENCY WAS DECLARED WITH MINNEAPOLIS ARTCC AND THE CREW INITIATED A RECOVERY BACK INTO KTVC.  CONTINUING WITH THE CHECKLIST, YAW DAMPER CIRCUIT BREAKERS AND A RUDDER BOOST CIRCUIT BREAKER WERE PULLED AND THE UNCOMMANDED FLIGHT CONTROL INPUTS CEASED AND DID NOT RECUR FOR THE REMAINDER OF THE FLIGHT.  AIRCRAFT LANDED WITHOUT INCIDENT ON RUNWAY 28 AT KTVC AT APPROXIMATELY 0710L EDT.   MAINTENANCE INVESTIGATION IS STILL UNDERGOING TO DETERMINE THE CAUSE OF THE MALFUNCTION.

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.
