With ten of the sport's biggest names already pre-qualified for Sunday's semi-finals, Hayboeck topped the rankings with a 101m jump for 128.6 points.
He was followed in by Germany's Andreas Wank, with 127.9 points, and Japanese jumper Reruhi Shimizu, who scored 126.2.
In total there were 40 qualifiers, with 11 competitors missing out, and they will line up alongside the pre-qualifiers, who each recorded an un-judged jump on Saturday as well.
Current World Cup leader Kamil Stoch's 100m jump was not among the biggest but the Pole faced a strong headwind as he took to the gate last of all.
But it was Germany's Severin Freund and Austrian Gregor Schlierenzauer who caught the eye, each flying 104m to offer a glimpse of what to expect in Sunday’s semi-final.
