## Discrepancy

ON APPROACH INTO KCPR FROM U68 THE PILOT OBSERVED ENGINE BEGAN TO RUN ROUGH FOLLOWED BY EGT AND CHT TEMPERATURES DRASTICALLY INCREASE. THE PILOT LANDED AT KCPR WITHOUT INCIDENT.

UPON TEARDOWN OF MAGNETOS, EDWARDS JET CENTER MAINTENANCE (KBIL) FOUND 25% OF THE TEETH ON THE DRIVEN PLASTIC MAGNETO DISTRIBUTER GEAR MISSING, ON THE RH MAGNETO.
