What happened
The pilot reported entering the traffic pattern for a landing on runway 1. While turning from base leg to final approach, he noted his airspeed was approximately 80 mph. Believing he could still execute a safe landing, he continued with the approach.
The aircraft touched down beyond the normal touchdown zone on a wet grass surface that offered poor braking action. Due to the reduced friction and excessive speed, the pilot was unable to bring the airplane to a stop within the available runway length. The aircraft departed the end of the runway and entered the adjacent woods, coming to rest between two trees.
The investigation
The investigation focused on the circumstances surrounding the landing and the subsequent departure from the runway. Examination of the site confirmed the aircraft had left the paved surface at the runway threshold and impacted vegetation. No mechanical failures were identified that would have contributed to the loss of control or stopping distance.
Findings
Contributing factors included the pilot's decision to continue the landing despite high airspeed and the wet grass conditions which provided inadequate braking capability. The aircraft sustained substantial damage upon impact with the trees.
