## Narrative

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

NARRATIVE: THE PILOT STATED THAT HE WAS AT CRUISE ALTITUDE (9,000 MSL) WHEN HE EXPERIENCED A VIBRATION IN THE #1 ENGINE. THE PILOT REDUCED POWER THEN LEANED AND ENRICHED THE MIXTURE WITH NO EFFECT. THE AIRCRAFT WAS 3 MILES AND 9,000' MSL FROM MKE. ENGINE WAS SECURED AND AS A PRECAUTIONARY MEASURE THE AIRCRAFT WAS LANDED WITH OUT FURTHER INCIDENT. THE CHIEF MECHANIC FOR C8AA, MR. N.B. UMPSTEAD ARRIVED AND PERFORMED MAINTENANCE ON THE #1 ENGINE. THE MECHANIC REPLACED A BAD SPARK PLUG. (CHAMPION REM 40E). THE ENGINE WAS OPERATIONALLY TESTED AND 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.
