Analysis

According to the pilot after takeoff he leveled off to gain airspeed and then entered a 60 degree pitch up attitude. The pilot stated at about 400 feet AGL he noticed the airspeed was lower than 'normal'. Shortly thereafter the aircraft stalled and entered a spin impacting the terrain next to the same runway from which it departed. Witnesses reported seeing the aircraft enter a near vertical climb after takeoff, spin and impact the terrain.
