## Narrative

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

N143K  ENGINE RUNNING ROUGH AT CRUISE ALTITUDE AFTER SWITCHING FUEL TANKS. SWITCHED BACK FUEL TANKS AND ENGINE STILL RUNNING ROUGH.

N143K REQUESTED TO GO BACK TO KCNO. N143K  LANDED SAFELY WITHOUT FURTHER INCIDENT.

09/13/2012 - #4-6 ENGINE SPARK PLUGS WERE FOULED, SPARK PLUGS WERE CLEANED AND AIRCRAFT WAS RETURNED TO SERVICE.

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.
