Probable cause

The failure of the plt to maintain directional control during the takeoff ground roll. Rain softened terrain adjacent to the runway surface is a contributing factor to the accident.

Sequence of events

Analysis

The accident airplane veered off the runway and nosed over in rain softened sod while attempting a takeoff. The plt related that it was his impression that he did not have complete control of the airplane during the latter portion of his takeoff roll and he decided to abort the takeoff because he could not maintain his desired track down the runway. The airplane then left the runway and nosed over. He also said that a post accident inspection revealed no mechanical defects in the airplane.
