This is a NERO helicopter Crash site due southeast of Copeland’s Camp. You can jump off the gap by using the dirt road northwest of the Wreckage as shown below. Make sure to gain some speed by starting off a distance then using your nitrous to give your Bike a little kick to reach the other side.
Once you reach the Wreckage, loot the body for an IPCA Tech, get the Injector from the protective case, the NERO Recorder beside it (Flight Data Recording - 2097), and of course the gas can. Refuel your Bike first then Fast-Travel out of the wreckage for your convenience.
