The plt said he was taking off on a dirt strip with a load of chemicals. After the acft accelerated to about 60 KTS, the left main landing gear collapsed. The acft then settled onto its left wing & was damaged. The plt said the attachingbolts on the gear had failed. An exam revealed the bolts were necked down in the area of the fracture (indicative of overload failure).
