What happened
The pilot reported that upon landing, the runway surface was covered with ice. He delayed applying the brakes during the initial rollout. When he eventually attempted to use the braking system, the aircraft was unable to decelerate sufficiently to stop within the remaining runway length.
Faced with the inability to stop, the pilot evaluated the option of executing a go-around. However, he determined that this maneuver was not feasible due to the presence of tall trees located near the end of the runway. Consequently, he elected to continue the landing rollout.
The aircraft continued past the end of the runway, traversed through some small trees, and ultimately came to a stop in a frozen creek.
The investigation
No mechanical examination or post-accident inspection details were provided in the source text regarding the condition of the aircraft systems or the runway surface beyond the reported ice coverage.
Findings
Contributing factors included the ice-covered runway conditions and the pilot's decision to delay braking. The presence of tall trees near the runway end precluded a go-around attempt, leading to the overrun into the adjacent terrain.
