## Narrative

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

N16JB DEPARTED KOXR FOR A 19 HOUR FLIGHT TO HILO HAWAII. WHEN THE A/C WAS APPROXIMATELY 11 NM WEST OFF SHORE FROM OXNARD THE PIC NOTICED HIS ENGINE RUNNING ROUGH, AND COULD NOT MAINTAIN ALTITUDE. THE PIC EXECUTED A 180 DEGREE TURN AND HEADED BACK TO OXNARD AIRPORT.  THE PIC CONTACTED OXR TOWER AND REQUESTED A LANDING ON RUNWAY 7.

NOT ABLE TO MAINTAIN ALTITUDE, AND LOSING POWER THE PIC DECLARED AN EMERGENCY WITH OXR TOWER. AT THIS POINT THE PIC KNEW HE COULD NOT MAKE RUNWAY 7, SO HE FOUND ^PRIVACY DATA OMITTED^ THAT RUNS PARALLEL TO RUNWAY 7, AND MADE HIS APPROACH TO IT. THE PIC LANDED WITHOUT INJURIES TO ANY PERSONS OR PROPERTY.

#4 CYL. WAS DEFECTIVE.   AFTER A VISUAL BOROSCOPE INSPECTION IT WAS EVIDENT THE EXHAUST VALVE IS STUCK OPEN.

Compare the reported make and model. For accidents, the NTSB's own investigation is the fuller record.
