'Skyfall' Stuntman Robbie Maddison -- Catches MAJOR Air ... Then Catches a Ride to the Hospital [VIDEO]

If you wanna see a grown man jack up his shoulder 25 feet in the air ... or a $250,000 video camera blasted into pieces -- motocross stud Robbie Maddison delivers both in these gnarly outtakes from his latest film.

TMZ has the never-before-seen footage of Robbie shooting "AIR.CRAFT" for DC Shoes -- and it includes shots of him pulling a Ruler over a mothballed airplane.

It looks like the stunt goes off without a hitch ... but in reality, Robbie separates his right shoulder in the middle of it -- and paramedics had to rush him to a hospital.

Robbie did all of Daniel Craig's motorcycle stunts in "Skyfall" ... and says the movie's stunt coordinator, Gary Powell, helped him come up with the insane jumps for 'AIR.'

"Gary would describe motorcycle stunts he hasn't been able to do in the movie world and I was like, that's totally possible."

Another casualty on set was the high-def video camera that got smashed into the ground during a low-angle driving shot -- a simple quarter-of-a-million-dollar blunder.
