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.

Narrative: history of flight: an uneventful flight was conducted from mci to the approach to fyv. At 15 miles from landing when reducing the manifold pressure from 27 to 25 inches the left engine made a loud bang and began smoking. The engine was secured in accordance with the check list and the smoke stopped. An uneventful engine out landing was made at fyv. Damage to the aircraft: no external damage was visible. When the left engine cowling was removed it was discovered that the engine #3 rod broke loose from the crankshaft. The rod had knocked a large piece out of the crankcase. Test and research: an inspection of the damaged engine did not reveal any obvious signs of maintenance malpractice or material defects. It appeared that a connecting rod bolt failed. Considering the TSO and operating history of this engine. The failure does not appear abnormal. The exact cause of the failure will be difficult to determine without laboratory analysis. This analysis is not planned. This incident closed.
