Analysis

The acft was landed with the landing gear partially extended during a forced landing after an engine failure. The plt delayed the extension of the gear because of the condition of the landing area. Examination of the engine showed a failure of the #2 connecting rod bearing strap due to fatigue. This failure was followed by failure of the remaining rods.
