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
After a normal touchdown, the aircraft continued rolling but failed to stop before reaching the perimeter hedge and a dry stone wall. The aircraft subsequently collided with both obstacles.
Pilot's Commentary
The pilot considered that he had overestimated the braking effectiveness available on the moist, downward-sloping grass surface.
