## Narrative

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

NARRATIVE: NEWLY LICENSED PRIVATE PILOT WAS BUILDING TIME IN THE EARLY MORNING HOURS OF SUNDAY 9/7/97 AND EXPERIENCED A ROUGH RUNNING ENGINE. THE AIRPLANE WAS VIBRATING VIOLENTLY SO THE PILOT DECIDED TO LAND THE AIRPLANE AS SOON AS POSSIBLE. LANDING WAS MADE IN A PARKING LOT OF A PAPER MILL. THERE WAS MINOR AIRPLANE DAMAGE AND THE PILOT WAS UNHURT. AFTER INVESTIGATION OF THE AIRPLANE IT WAS DETERMINED THAT THE INCIDENT OCCURRED DUE TO VALVE PROBLEMS IN THE #4 CYLINDER IN WHICH THERE WAS LITTLE COMPRESSION. CHECKED ENGINE COMPRESSION ON ALL (4 EA) CYLINDERS, FOUND COMPRESSION ON CYLINDERS #1, #2, AND #3 TO BE NORMAL, BUT THE #4 CYLINDER WAS VERY LOW. REMOVED #4 CYLINDER ROCKER ARM COVER AND BOTH ROCKER ARMS, AND CHECKED VALVES FOR CARBON BUILD UP. CARBON BUILD UP WAS FOUND AND AFTER REMOVAL THE COMPRESSION IN #4 CYLINDER WAS THE SAME AS THE OTHER 3 CYLINDERS. AIRCRAFT WAS SERVICED WITH 100LL GAS. OPERATOR WILL SUBMIT M OR D REPORT.

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.
