Analysis
The pilot stated that he and the co-pilot had just begun to taxi to the runway from their hangar. The airplane traveled about 150 ft when the ground gave way (sink hole due to a broken water main) under the left main landing gear. The landing gear collapsed, which resulted in substantial damage to the left-wing spar and lower fuselage. The left engine propeller blades were also damaged.
