NTSB narrative
THE TOW PLANE AND THE GLIDER IT HAD TOWED TO PATTERN ALT COLLIDED ON THE FINAL APPROACH OF THE TRAFFIC PATTERN. THE TOW PLANE WAS SUPPOSED TO FOLLOW THE SAILPLANE & LAND AFTER ITS TOW ROPE DROP. THERE WAS A LOW SUN GLARE ON THE HEADING OF THE BASE LEG. THE CFI IN THE GLIDER SAID HE DID NOT SEE THE TOW PLANE UNTIL THE GLIDER WAS AT ABOUT 200 FT AGL & 200 YARDS FROM TOUCHDOWN, THEN HE SAW A 'WHITE MOVEMENT' TO HIS LEFT. HE TURNED RIGHT, BUT WAS TOO LATE TO AVOID A COLLISION. HE SAID THERE WERE NO RADIOS IN EITHER ACFT.

Source notes (4)
- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
