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.

(-23) During climb out, the pilot noticed the right engine oil pressure gage indicating a significant increase in pressure. When the right engine started to run rough the engine was secured and the propeller was feathered as a precaution. The aircraft returned to the airport of departure and landed without further problems. After the right cowling was removed to investigate the rough running engine, it was found that the engine had blown the number 4 cylinder off of the crankcase, allowing the piston to cock in the cylinder barrel and throwing the number 4 rod, damaging the crankcase. The engine cannot be rotated by hand.
