Incident Overview
An instructor pilot was performing a demonstration of a simulated engine-out forced landing for a student pilot. The aircraft was on final approach to a 2,940-foot grass landing strip. The instructor allowed the airspeed to remain too fast during the approach.
Approach and Touchdown
Because the airspeed was higher than desired, the aircraft floated further down the runway during the flare than intended. The instructor was unable to achieve touchdown until approximately 1,000 feet of the runway had passed.
Runway Excursion
After touchdown on the wet grass, the instructor attempted to bring the aircraft to a stop before reaching the end of the runway. However, the stopping distance was insufficient, and the aircraft departed the far end of the runway. Following the overrun, the aircraft collided with a nearby fence post.
