well, that small nose wheel makes landing on grass risky business. it's not designed for rough or soft fields but that doesn't stop folks from trying.

The aircraft, an Experimental Jeff Fosdick built Vans RV-6A, Registration (*unconfirmed) N298Z, sustained substantial damage subsequent to the nose over during landing at Spirit Airpark (DE20), Townsend, Delaware. The sole pilot onboard the Amateur Built single-engine tailwheel equipped airplane received minor injuries.

well, not much to learn here. it is just another example of a nose wheel flip over on rough or soft terrain.

Analysis
The pilot reported that he was in the traffic pattern for landing at his home airport. The turf runway was 3,300 ft-long and 100 ft-wide, and the pilot described its condition as dry, but “pretty bumpy.” The approach and landing were normal, with the main landing gear touching down first, about 60 mph. After he lowered the nose landing gear to the runway, the airplane nosed over and came to rest, inverted. He was met by neighbors and first responders who assisted him out of the airplane and was taken to a local hospital for treatment of his injuries. An inspector with the Federal Aviation Administration responded to the accident site and examined the wreckage. There was substantial damage to one wing, the fuselage, and the vertical stabilizer. He reported that the landing surface was bumpy; however, he could not determine an exact location where the landing gear dug in. After the wreckage was recovered, the landing gear was examined. The nose landing gear leg was found unbroken, but bent aft about 30-40°, consistent with the nose wheel digging into rough or bumpy turf. The nose wheel casted and turned freely without restriction. There were no areas of preexisting mechanical anomaly found.

Probable Cause and Findings
The National Transportation Safety Board determines the probable cause(s) of this accident to be: An inadvertent encounter with rough or soft terrain during landing, resulting in a bent nose landing gear leg and subsequent nose over.
