Probable cause
The unqualified pilot's failure to maintain airspeed (vso) while maneuvering to land, which resulted in an in flight loss of control, stall spin, and collision with terrain.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The airplane was observed by witnesses in the traffic pattern at 150 feet AGL with a 20 to 30 degree nose up attitude. The airplane began a left turn towards the runway with a 30 degree angle of bank. The left wing dropped down 90 degrees, the nose pitched down 60 degrees, and the airplane disappeared below the tree line colliding with the terrain. The airplane sustained substantial damage. The owner stated in an interview with the FAA that the PIC stalled the airplane. The pilot did not hold a rating to fly airplanes and in addition, did not have a current medical certificate.
