Aircraft Accident/Incident Report

NTSB Narrative Summary Released at Completion of Accident

GROUND WITNESSES OBSERVED THE ACCIDENT SEQUENCE AND REPORTED THAT THE GLIDER WAS BEING TOWED ALOFT BY A TOW PLANE. THE WITNESSES SAID THE TOW PLANE LIFTED OFF NORMALLY; HOWEVER, THE GLIDER DID NOT SEEM TO LIFT OFF IN A NORMAL MANNER. AS THE GLIDER ACHIEVED ABOUT 50 FEET AGL, THE PILOT RELEASED THE TOW LINE. THE GLIDER THEN BANKED SLIGHTLY TO THE LEFT, THEN ROLLED TO THE RIGHT. THE RIGHT ROLL CONTINUED UNTIL THE GLIDER WAS AT A VERY STEEP BANK ANGLE AND ENTERED A SPIRAL, WHICH CONTINUED TO GROUND IMPACT. ACCORDING TO THE WITNESSES, NO ONE SAW THE PILOT PERFORM A CONTROL CONTINUITY CHECK AFTER ASSEMBLY OF THE GLIDER PRIOR TO TAKEOFF. A FAA AIRWORTHINESS INSPECTOR RESPONDED TO THE ACCIDENT SITE AND EXAMINED THE GLIDER. HE REPORTED THAT THE GLIDER IS EQUIPPED WITH QUICK DISCONNECT FITTINGS ON THE CONTROL SYSTEM PUSH/PULL TUBES IN THE WING CENTER SECTION. THE FITTINGS ALLOW THE CONTROL SYSTEM TO BE DISCONNECTED AND RECONNECTED AS THE WINGS ARE REMOVED OR INSTALLED. THE RIGHT AILERON/FLAPERON FITTING WAS FOUND DISCONNECTED.

NTSB Probable Cause Narrative

the pilot's failure to properly connect the aileron/flaperon quick disconnect fitting during assembly of the glider, and his inadequate preflight inspection.
