Analysis

The acft landing gear collapsed during a forced landing after an engine failure. The pilot said he lost manifold and oilpressure and turned back toward grand junction when the engine began making loud noises. A landing was made on a slippery road and the acft skidded and collapsed the gear. Teledyne-continental decided that a thrust washer half had been left out of the engine during manufacture. This allowed excessive movement of the crankshaft which side-loaded and failed #2 connecting rod and damaged #1 rod.
