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

THE STUDENT PLT & INSTRUCTOR (CFI) WERE PRACTICING PATTERN WORK & LANDINGS. DURING THE 1ST 3 PATTERNS, THE WIND WAS CALM, HOWEVER, BY THE TIME THEY WERE ON THEIR 4TH PATTERN, THE WIND INCREASED & BECAME GUSTY. WHILE THE STUDENT WAS FLYING THE PATTERN, HE ALLOWED THE GLIDER TO GET LOW ON BASE LEG. THE CFI BELIEVED THERE WOULD BE NO PROBLEM, BUT ON FINAL, THE AIRSPEED DECREASED & THE CFI TOOK CONTROL. HE LOWERED THE NOSE TO GAIN AIRSPEED, BUT THEY ENCOUNTERED UNEXPECTED, SEVERE SINK & WIND GRADIENTS. SUBSEQUENTLY, THE GLIDER CONTACTED THE TOP OF CORN GROWING NEAR THE END OF THE RWY. THE RIGHT WING ENCOUNTERED MORE OF THE CORN THAN THE LEFT WING & THE GLIDER SWERVED RIGHT & IMPACTED THE GROUND SIDEWAYS.
