Taken from league of legends wiki:
"The multi-attack effect is similar to
Triggering
On-hit effects are disabled on the latter four attacks and will not be triggered even by Wind's Fury. Each flurry only applies on-hit damage from Runaan's Hurricane once.
Wind's Fury's splash damage is affected by the damage modifier - dealing 「 15 (+5.75 / 6 / 6.25 / 6.5 / 6.75% AD) damage per arrow 」「 15 (+28.75 / 30 / 31.25 / 32.5 / 33.75% AD) damage per flurry 」 to each secondary target."
