Primary finding
Probable cause
Inadequate altitude due to an improperly planned approach which resulted in a tree strike on final approach.
Investigator assessment
Analysis narrative
The pilot was conducting an experimental flight test which called for an unpowered descent. The approach was initiated with both engines shut off. Initially the pilot was high on final and 's' turned to loose altitude. During the last 's' turn he noticed he was too low and struck a tree just short of the approach end of the runway. The airplane came to rest beyond the approach end of the runway.
