## Narrative

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

MARCH 06, 2012AT 15:30 EST, 20:30Z, THE ALLEGHENY FLIGHT STANDARDS DISTRICT OFFICE RECEIVED A CALL FROM THE REGIONAL OPERATIONS CENTER THAT A CE-310L AIRCRAFT, N2272F, HAD LANDED GEAR UP ON RUNWAY 15 AT THE JOHNSTOWN-CAMBRIA COUNTY AIRPORT (KJST). THEY REPORTED THAT THE PILOT HAD CIRCLED THE AIRPORT TO BURN-OFF FUEL LOAD IN PREPARATION TO LAND WITH THE LANDING GEAR RETRACTED AFTER HAVE BEEN UNSUCCESSFUL IN PERFORMING AN EMERGENCY GEAR EXTENSION.  THE PILOT AND TWO PASSENGERS DEPLANED WITHOUT INJURY. INSPECTORS ARRIVED AT KJST AND FOUND THE AIRCRAFT AT RUNWAY 15'S CENTERLINE AT APPROXIMATELY THE 3500 FOOT POINT.  THE INSPECTORS WALKED THE RUNWAY FROM TOUCHDOWN POINT TO AIRCRAFT AND PHOTOGRAPHED DEBRIS AND MARKINGS. ^PRIVACY DATA OMITTED^, THE PILOT IN COMMAND, STATED THAT THE LANDING GEAR WOULD NOT EXTEND WITH THE USE OF THE EMERGENCY SYSTEM DESPITE SEVERAL ATTEMPTS.  ON WEDNESDAY MARCH 7, AN INSPECTOR RETURNED TO KJST AT 07:00 TO WITNESS THE AIRCRAFT REMOVAL FROM THE RUNWAY.  MAINTENANCE PERSONNEL ATTEMPTED TO MANUALLY EXTEND THE LANDING GEAR AFTER LIFTING THE AIRCRAFT WITH A HOIST, BUT THE LANDING GEAR WAS UNABLE TO BE EXTENDED.  INITIAL EXAMINATION OF THE LANDING GEAR GEARBOX AND LINKAGE REVEALED THE BELL CRANK AND CONTROL RODS THAT MOVE THE LANDING GEAR WERE OUT OF RIG, DRIVEN PAST THE POINT THAT THE LANDING GEAR WOULD HAVE NORMALLY STOPPED IN THE UP AND LOCKED POSITION.    THE GEAR MOTOR WAS REMOVED AND FOUND TO BE BOTH LOCKED AND BURNED FROM BEING RUN LONGER THAN REQUIRED AND FROM THE HEAVY LOAD INDUCED FROM THE LINKAGE BINDING.  DAMAGE WAS FOUND AT THE DRIVE SPLINES ON THE GEARBOX REDUCTION UNIT AT THE MOTOR MOUNTING PAD.  IT APPEARS THAT THE "UP" LIMIT SWITCH MAY HAVE FAILED DURING THE PREVIOUS TAKE-OFF AND GEAR RETRACTION, ALLOWING THE GEAR MOTOR TO CONTINUE TO RUN UNTIL FAILURE OCCURRED.  EMERGENCY MANUAL EXTENSION OF THE LANDING GEAR WAS NOT POSSIBLE BY THE PILOT DUE TO THE "JAMMED" CONDITION OF THE CONTROL RODS AT THE ACTUATOR.  A SERVICE DIFFICULTY REPORT WILL BE FILED BY THE REPAIR FACILITY WHEN POSITIVE IDENTIFICATION OF THE FAILED PART CAN BE DETERMINED.  END

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.
