Making Mobs Fly With Elytras With Commands

So I kinda gave mobs elytras to fly... It's kinda funny but probably not a good idea in survival... Think about how mobs can fly in and just kill you out of no where...

The command:
repeat: execute as @e[tag=flyingmob] at @s unless data entity @s {ArmorItems:[{},{},{count:1,id:"minecraft:elytra"},{}]} if block ~ ~-3 ~ air run item replace entity @s armor.chest with minecraft:elytra
chain: execute as @e[tag=flyingmob,nbt={FallFlying:0b}] at @s if block ~ ~-3 ~ air run data merge entity @s {FallFlying:1b}
chain: execute as @e[tag=flyingmob,nbt={OnGround:1b}] at @s run item replace entity @s armor.chest with air
