Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot reported that during the landing he let the "nose come down and used brakes which caused the low clearance gear leg to dig in and begin bending." The airplane's propeller and wing subsequently contacted the "undulating" grass strip. The pilot reported no mechanical malfunctions with the airplane during the accident flight. The pilot's safety recommendation was to replace the accident gear leg with the "new revision ... from Vans [aircraft] which has greater ground clearance."
