THE ACFT WAS PARKED IN THE HANGAR AND NO PERSONNEL WERE AROUND OR PRESENT WHEN THIS OCCURED. THE RT WING TIP CONTACTED THE HANGAR FLOOR WITH ENOUGH FORCE TO WRINKLE THE TOP OF THE WING AND DAMAGE THE RT AILERON.

IF THIS FAILURE WOULD HAVE OCCURED DURING TAXI, TAKEOFF OR LANDING IT COULD HAVE RESULTED IN LOSS OF LIFE.
