The NTSB's narrative final · quoted from the NTSB record

The pilot, who worked as an aviation mechanic for the aircraft manufacturer, installed vortex generators on the wings and fuselage of a Rans S-11. He then flew the S-11, while a chase plane followed. The S-11 pilot slowed the airplane to let the chase plane catch up. The pilot of the chase plane reported that the S-11's altitude was about 1,500 feet AGL, but the airspeed was slow. He observed the airplane doing slight Dutch rolls and '...just mushing along.' The S-11's nose pitched down and started a 1/4 spin to the left. The aircraft started to pull up from the nose down spin attitude, and then made a shallow arc before impacting the ground. The pilot of the S-11 was not a test pilot. He had a total of 3 hours in the S-11. The S-11 pilot reported the flight was a personal flight. The company did not have a policy for test flying airplanes. The engine and flight controls exhibited continuity.
