Sequence of events

Analysis

The pilot of the tailwheel-equipped airplane reported that during the takeoff roll on an off airport airstrip the airplane hit a soft spot, and he elected to abort the takeoff. He further reported that he was unable to stop prior to impacting a group of alder trees at the end of the airstrip. The airplane sustained substantial damage to the empennage. According to the pilot there were no preimpact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.
