NTSB Factual Report

The pilot reported that during approach, he reduced power and was convinced he had enough altitude to land on the grass runway. The pilot further reported that the airplane impacted a ditch prior to the runway which resulted in a sheared nose landing gear, collapsed main gear, and then slid about 200 feet.

The airplane sustained substantial damage to the left wing.

The pilot reported that there were no preimpact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.

NTSB Probable Cause

The pilot's descent below the intended glidepath during the approach, which resulted in an impact with a ditch prior to the runway.
