The airplane was on takeoff run when the right landing gear axle broke. It was not possible to maintain directional control and the gear leg dug into the terrain. The airplane ground looped and the tail impacted the terrain. Subsequent examination of the axle revealed that the failure was due to fatigue cracking, but the source of the fatigue was not determined.
