## Narrative

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

AFTER TAKEOFF FROM PORT GRAHAM, PILOT SET AIRCRAFT TO CLIMB POWER. AT AN ALTITUDE A LITTLE ABOVE 2000 FEET, PILOT HEARD A LOUD ?POP? AND EXPERIENCED A PARTIAL LOSS OF ENGINE POWER. PILOT STATED THAT HE HAD SUFFICIENT ALTITUDE TO RETURN TO THE PORT GRAHAM AIRPORT SAFELY. THE LANDING WAS COMPLETED WITH NO DAMAGE TO THE AIRCRAFT. DIRECTOR OF MAINTENANCE EVALUATED THE ENGINE AND FOUND A LARGE HOLE IN THE ENGINE CASE ABOVE #4 CYLINDER. THE CONNECTING ROD LOWER PORTION WAS MISSING WITH THE CRANKSHAFT JOURNAL CLEARLY VISIBLE. AIRCRAFT WAS PICKED UP BY HELICOPTER AND BROUGHT TO HOMER, ALASKA. NO SERVICE DIFFICULTY REPORT WAS FILED BY THE COMPANY WITHIN THE REQUIRED 96 HOUR TIME LIMIT.

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.
