## Narrative

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

NARRATIVE: ON FRIDAY, MARCH 28, 1997, AT APPROXIMATELY 2000 PST, PIC ROBERT HICKS WAS FLYING AERO COMMANDER GA-695-695, N3U, IN LEVEL FLIGHT AT 6500 FEET WITH A CRUISE POWER SETTING OF 60% WHEN HE ENCOUNTERED A 20-40% FLUCTUATION ON THE LEFT ENGINE. MR. HICKS REDUCED THE POWER SETTING AND THE FLUCTUATION CONTINUED WHILE THE RPM INCREASED TO 103-105. MR. HICKS FURTHER REDUCED THE POWER, FEATHERED THE PROPELLER, AND CLEANED UP THE AIRPLANE. UPON FURTHER INSPECTION IT WAS DISCOVERED BY MAINTENANCE PERSONNEL THAT THE SWIVEL HAD JAMMED IN THE OIL FILTER, THE OIL BYPASS BUTTON HAD POPPED, THE OIL WAS DISCOLORED DARKER THAN NORMAL, AND THE PROPELLER WOULD NOT ROTATE. THE MAINTENANCE FACILITY TOOK AN OIL SOAP SAMPLE AND IS SENDING THE ENGINE TO EAGLE CREEK AVIATION CRS, WHO ACCOMPLISHED THE LAST HSI AND GEAR BOX EXTENSION, FOR AN ENGINE TEARDOWN. THIS INCIDENT IS CLOSED.

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.
