Narrative:
The noncertificated pilot reported taking off from his private airstrip and flying to a friend's grass airstrip. Upon landing, he found that the destination airstrip was too short. The airplane overran the end of the runway and impacted a stump. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.

Probable Cause: The noncertificated pilot's inadequate preflight planning, which resulted in landing on a runway of inadequate length and subsequent runway excursion.
