## Narrative

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

NARRATIVE: DURING VFR/VMC FLIGHT FROM YAKIMA, WA (YKM) TO PROVO, UTAH, PILOT OF N97702 REPORTED A STUCK ENGINE THROTTLE. PILOT SHUT DOWN ENGINE AND LANDED AT PASCO, WA (PSC) WITHOUT INCIDENT. MECHANICS AT PASCO, WA DISCOVERED DURING THEIR INVESTIGATION THAT THE REQUIRED CASTELLATED NUT AND COTTER KEY WAS MISSING FROM THE BOLT THAT SECURES THE ENGINE THROTTLE CABLE ROD-END TO THE CARBURETOR. THIS MISSING HARDWARE ALLOWED THE BOLT TO MOVE ENOUGH TO CAUSE THE THROTTLE TO JAM. A NEW BOLT, NUT AND COTTER KEY WAS INSTALLED AND ENGINE WAS FUNCTIONALLY CHECKED AND FOUND TO PERFORM SATISFACTORILY.

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.
