Crossair flight 571, a Saab 340 (HB-AKL) from Nürnberg to Zürich, nearly collided mid-air with CSA flight 584, a Tupolev Tu-154 (OK-UCF,) en route from Prague to Zürich.
Separation was 500 ft horizontally and 100 ft vertically.
CAUSE:
The incident occurred because the air traffic controller cleared an aircraft to descend to a flight level that had not yet been vacated by an intersecting aircraft that was also descending.
Contributing to the incident were:
- Overlap of labels on the radar screen;
- excessively high descent rate of the CSA aircraft;
- low descent rate of the Crossair aircraft.
