From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry 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.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

-Pilot reported rising oil temp while in cruise flight at FL 011. Oil temp indication maxed out at 240 degrees. Pilot requested change in altitude to FL 009. Oil temp indication went down to approximately 215 degrees for a short time and began to climb again. Pilot requested divert to konl. The engine failed and lost power forcing pilot to make an off-airport landing.

-Traveled to konl and observed no aircraft damage due to off airport landing.

-Removed engine cowl and determined aircraft sustained catastrophic engine failure due to an unknown internal issue. The case area between #5 and #6 cylinders had a roughly baseball size hole in it. Engine model IO-550-N serial number 690125.

-A connecting rod cap with bolts still attached was laying on top of the engine. The connecting rod cap and bolts exhibited mechanical damage.

-A broken section of piston ring was on top of the engine along with a connecting rod bearing. The bearing had a stamped part number on it. An internet search determined the bearing part number 642398 listed as an engine manufacturer bearing. The full bearing stamp is 05-06 112 642398 f

- The connecting rod bearing appeared to exhibit minor mechanical damage and no discoloration.

-The crankshaft journal appeared to exhibit no mechanical damage or discoloration.

-The engine oil pan exhibited mechanical damage (dents) exerted from interior to exterior surface. Additionally, the oil pan had approximately 3 holes punched through the exterior surface.
