Hello Cars Racing Fans!
This achievement requires of you to perform 6 Air tricks on 1 single jump. The easiest way is to enter a Stunt Rave Event which will have ramps for you to jump. So first fill at least 1 Turbo bar segment and press X to turbo before the ramp, then at the apex of the ramp press the A button and hold it to jump higher then immediately move the Analog stick either left or right and hold it, I recommend the right side to do 180 spins which your car will execute quickly, if gotten sufficient air and speed you can easily make the 6 air trick and land safely.
