This story mission becomes available after completing Wingman. Since you’ll be facing enemies that can shot you down, having the Auto Repair perk will help a lot. Don’t forget that you can also call in Nick to help you in this mission. He’ll be quite useful in winning the dogfights later on. This mission seems to be bugged as well since if you get shot down and the checkpoint reloads, the other objectives will be automatically completed and the mission will end.
Head to Rye and Sons Aviation and hop on the plane to start the mission. Kim will be providing you instructions via radio. First, follow the mission marker to the fuel pump. It will be easier to destroy it by dropping a bomb so line up to the target, enter bomber view then drop the bomb as the target comes into view of your reticule.
After destroying the pump, you’ll have to deal with two convoys in different locations. Follow the mission markers and take them out as well, preferably by dropping a bomb on top of them.
Once the two convoys are dealt with, you’ll have to shoot down two enemy choppers. If you sustained damage already from the convoys attacking you from the ground and if you fail to take out these choppers quickly, you’ll get shot down at this point (unless you have Auto Repair).
After taking out the choppers, you finally need to take out two Chosen planes. They’ll be a bit harder to deal with since they’re using more agile planes made specifically for combat. After taking out the planes, the mission will be complete.
