What happened
The pilot selected an old road covered with high weeds as the site for landing. This same location had been used successfully by the pilot just one week prior. During the landing roll, the left wing of the aircraft became entangled in the dense vegetation. To correct the resulting deviation from the intended path, the pilot applied right rudder input to straighten the aircraft's course.
Despite these corrective efforts, the aircraft departed the paved or hard-packed surface of the road and entered a soft sand swale ditch adjacent to the landing area. Upon entering this depression, the nosewheel dug deeply into the loose sand. The resistance caused by the buried nosewheel resulted in the aircraft nosing over onto its fuselage.
The investigation
The physical examination of the site revealed that the chosen landing area was an old road characterized by high weeds. The pilot confirmed that this specific location had been utilized for a previous operation within the preceding week, indicating familiarity with the terrain despite the overgrown conditions.
