Aircraft involved
Probable cause & findings
The pilot’s decision to taxi the airplane through tall grass without visual reference to the surface which obscured uneven terrain.
Factual narrative
The pilot reported he landed on an unimproved strip, and then elected to reposition the airplane through an area of tall grass. During taxi, the main landing gear wheels hit a dip in the uneven terrain, and the airplane nosed over, sustaining substantial damage to the rudder and right wing. The pilot reported that there were no pre-accident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
