This NERO helicopter Crash site is located due west of the Hot Springs Camp. You’ll need to use your Motorcycle to jump via dirt ramp across the gap and reach the actual crash site. Make sure to approach the ramp from a distance to gain momentum and use your nitrous to give your Bike an additional Boost just before you jump off the ramp.
From there, you can continue on foot uphill where the Wreckage and loot lies. Get the IPCA Tech from the mutilated corpse, the Injector, a NERO Recorder (Flight Data Recording - 2041), and a gas can. Refuel your Bike and just simply Fast-Travel out of this location.
