The payload impacted 2km North east of the launcher. The thrusting motor continued to fly down range. All objects were contained within safe areas, causing no damage on human beings or property. The methodical approach of the conducted failure Investigation is introduced and the most probable failure cause is identified. A summary of performed studies is given and it is described how the most probable failure cause was deduced. Finally, recommendations and restrictions referring technical and procedural aspects are covered which are planned to be applied in future campaigns.
