THE PILOT/CO-OWNER HAD ONLY A GLIDER CERTIFICATE, BUT HE ELECTED TO FLY THE HOME BUILT AIRPLANE ON ITS MAIDEN FLIGHT. AFTER DEPARTING ON RUNWAY 24, HE INITIATED A RIGHT TURN ABOUT 3/4 MILE WEST OF THE AIRPORT. WHILE TURNING AT ABOUT 200 FT AGL, THE AIRPLANE ENTERED A SPIN & IMPACTED THE GROUND IN A VERTICAL DESCENT. AN INVESTIGATION REVEALED THE PILOT HAD ABOUT 82 HRS OF FLIGHT TIME, OF WHICH, APRX 25 HRS WERE IN SINGLE ENGINE AIRPLANES.
Probable Cause: FAILURE OF THE PILOT TO MAINTAIN SUFFICIENT AIRSPEED, WHILE TURNING AFTER TAKEOFF, WHICH RESULTED IN A STALL/SPIN. CONTRIBUTING FACTORS WERE: IMPROPER PLANNING/DECISION BY THE PILOT BY TEST FLYING AN AIRPLANE THAT HE WAS NOT PROPERLY CERTIFICATED TO OPERATE, HIS LACK OF FAMILIARITY WITH THE AIRCRAFT, AND OVERCONFIDENCE IN HIS PERSONAL ABILITY.
