THE PVT PLT & HIS INSTRUCTOR (CFI) DEPARTED OAKLAND ON A VFR INSTRUCTIONAL FLT TO HAYWARD IN A ROBINSON R22 HELICOPTER. THEY LANDED ON TAXIWAY (TWY) 2, THEN TOOK OFF FOR ANOTHER TRAFFIC PATTERN & LANDING. THE CFI THEN INSTRUCTED THE PVT PLT TO MAKE A RUNNING TAKEOFF. DRG THE TAKEOFF GROUND RUN, THE HELICOPTER'S LEFT SKID STRUCK AN ALIGNMENT DEVICE WHICH WAS PROTRUDING ABOVE THE TWY SURFACE. AFTER HITTING THE DEVICE, THE HELICOPTER ENTERED A VIOLENT LEFT YAW & BECAME AIRBORNE. THE CFI WAS ABLE TO ARREST THE YAW, BUT HE COULD NOT STOP A RAPID DESCENT THAT DEVELOPED. SUBSEQUENTLY, THE HELICOPTER'S UNDERCARRIAGE, VERTICAL STABILIZER, RIGHT DOOR & FUSELAGE SKIN WERE DAMAGED. AN INVESTIGATION REVEALED THAT CONTRACTORS HAD RECENTLY PAINTED THE TWY & HAD LEFT THE ALIGNMENT DEVICE PROTRUDING ABOUT 1/2 INCH ABOVE THE SURFACE OF THE TWY.
