Tier 1: Find the Wreckage
Travel straight North by North West following the water until you reach the wreckage.
Tier 2: Eliminate Scavenging Ghouls & Chieftain Unghk
Once there, kill 8 ghouls that are trying to scavenge things from the plane. Once that is done, head to the next marker and kill Chieftain Unghk. He has no special attacks that you need to be aware of. When he dies, the mission will complete.
