Analysis

The plt stated that during the ground roll to takeoff, after raising the tail, the rt side of the acft began to sink. The main gear then broke out from under the acft causing it to veer off the lt side of the rwy. According to an FAA inspector who examined the airstrip, a mud hole was located on the rwy at the location where the tail wheel would be lifted off. He further stated that the plt got too close to the soft spot & the rt main landing gear attach bolt broke after the gear travelled into the mud hole. Metallurgical examination of the failed landing gear attach bolt revealed that it failed due to overload.
