When you first reached Kopoh you may have noticed the ship stuck in the mud and a Pit Droid that you unfortunately told you can't help.
Once you unlock the Lift & Slam ability
go back to the pit droid and use the lift ability

&

to lift the ship out of the mud.
The ship is in Gorge Crash Site in Kopoh (Shown in video). Make sure to talk to the pit droid after you unlock the achievement as well.
