An aircraft landing in an open field on moist, downward-sloping grass failed to stop before colliding with a perimeter hedge and dry stone wall. The pilot reported overestimating braking effectiveness.
Landing Details
The aircraft was conducting a landing in an open field. The pilot elected to land in the direction of the surface wind, which was 280 degrees at 6 to 8 knots. The landing touchdown was reported as normal.
Terrain and Weather
The field's terrain featured an upward slope leading to a crest, followed by a downward slope. The grass covering the field was moist at the time of the landing.
Incident Sequence

Pilot's Commentary
The pilot considered that he had overestimated the braking effectiveness available on the moist, downward-sloping grass surface.
