Analysis

While conducting a post-flight walkaround inspection, the pilot discovered two through penetrations of the ventral vertical stabilizer and damage to three propellor blade leading edges, likely from foreign object debris. The stabilizer sustained substantial damage. The source of the debris could not be determined. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. This airplane is an exported former Beechcraft Starship 2000A that was issued a new special airworthiness certificate as an experimental Enterprise during import.
